-<message_key> = <message text>
-
-The message_key will become the #define or static final name of the message 
-definition with a module error prefix. The message_text will become a 
-inline comment depending on usage
-
-EXAMPLE resource input file. NOTE that only the %s format spec is supported
-for supplying supplemental data for ioctl status. If a line ends with "@@" it
-it indicates that a byte address and length will be supplied with the status
-code to provide arbitrary data for shipment to userspace (a "bytestream"). 
-Bytestreams are intended for asynchronous status output from coresw and are 
-not supported for ioctl status.
-
-NOMINOR = No more minor numbers available
-ARRBOUNDS = Array bounds check exceeded %s size limit
-INTERNALDUMP = Internal state dump @@
-
-EXAMPLE C header file generated with "errgen -c SV":
-
-#define SV_ENOMINOR   0x00030001 /* No more minor numbers available */
-#define SV_EARRBOUNDS 0x01030002 /*Array bounds over %s size limit */

- * read_config()
- *
- * DESCRIPTION: Read the lines in a configuration file and return the
- *		pairs of devices to be mirrored/enabled/disabled/updated.
- *		The format for the configuration file is as follows:
- *
- *		fromhost fromfile frombitmap tohost tofile tobitmap
- *
- *		where fromfile is the primary device which is local to the
- *		fromhost subsystem, tofile is the secondary device which is
- *		local to the tohost subsystem, and type is 1 if the device
- *		a simckd device or 0 otherwise.  Any line preceeded by a '#'
- *		is considered to be a comment.
- *
- * Inputs:
- *	char *config_file	Name of configuration file for rdcadm
- *
- * Outputs:
- *	int i			Number of pairs of devices
- *
- * Side Effects: The 0 to i-1 entries in the pair_list are filled.

-# NWS DataServices within SunCluster reconfiguration script.
-#
-# Description:
-#
-# This script is called from /usr/cluster/lib/sc/run_reserve at
-# appropriate times to start and stop the NWS DataServices as SunCluster
-# disk device groups are brought online or taken offline.
-#
-# SNDR configuration requires that a resource group to be configured.
-# 1. The resource group name should be same as device group name with -stor-rg
-#    added. e.g. if device group name is abc-dg then resource group name
-#    would be abc-dg-stor-rg. 
-# 2. It should have 2 resources in it, unless one of the resource types is the
-#    SUNW.GeoCtlAVS. One of type SUNW.LogicalHostname and either SUNW.HAStorage
-#    or SUNW.HAStoragePlus types. Resource type versioning is ignored.
-#    HAStorage type resource, should have ServicePaths property set to
-#    device group name. HAStoragePlus type resource, should have either the
-#    FilesystemMountPoints pointing to a files system associated with the
-#    device group name, or GlobalDevicePaths property set to device group name.
-#    LogicalHostname type resource should have a failoverIP address in it and
-#    it will be used by SNDR to communicate with the secondary side.
-#
-# As SNDR requires that the LogicalHost (failover) IP address which is a
-# part of resource group for SNDR, to be hosted on the same node where the 
-# device group is, it tries to move the resource group also alongwith the
-# device group, in become_primary case of run_reserve script. While
-# in primary_to_secondary case, it will try to kill the switchover function
-# if it is still running in background, after stopping NWS data services.
-# 
-# Usage:
-#
-# /usr/cluster/sbin/dscfg_reconfigure { start | stop } diskgroup
-#
-# Configuration:
-#
-# Scripts to be run should have been symlinked into $NWS_START_DIR and
-# $NWS_STOP_DIR.  Note that the scripts are processed in lexical order,
-# and that unlike /etc/rc?.d/ there is no leading S or K character.
-#

-#
-# 0 - success
-# 1 - error

-# This function calls switchfunc function in background, to switch the

-# out of switchover of resource group from within device group switchover.
-#
-# In run_reserve context, we are doing the device group switchover, trying to

-# the device group is online and the device group can not become online until the

-The error resource files in *.err of the subdirectories must only contain
-embedded "%s" format descriptors for info to be edited into messages returned
-from ioctls. Special "bytestream" data to be passed with status
-(implementation TBD) is signified by "@@@" as the last three characters of
-the  message text. Don't try to use this to pass a bytestream back via an
-ioctl: it will just trigger an error.
-
-After early development when the first creation of foreign language locale 
-files by the company for a product takes place you are NOT free to make edits
-to existing messages or their status code labels nor do any insertions. You
-may ONLY ONLY ONLY append new lines to the end of the file.

-.SH DESCRIPTION
-.LP
-Point-in-Time Copy software is a point-in-time snapshot feature of the Solaris
-operating system.
-.sp
-.LP
-A Point-in-Time Copy snapshot is an instantly-available, time-fixed, replicated
-view of a momentarily quiesced volume. Once a snapshot is taken, Point-in-Time
-Copy software allows immediate read/write access to both the master and shadow
-volume data.
-.sp
-.LP
-Point-in-Time Copy software tracks the differences between the master and
-shadow volumes (caused by writes) from the moment that the snapshot was
-established. This capability allows applications accessing the master volume's
-data to move forward in time independently of applications accessing the shadow
-volume's data, and vice-versa.
-.sp
-.LP
-The Point-in-Time Copy software's tracking of differences between the master
-and shadow volumes facilitates a fast resynchronization or a full copy at a
-later time. The volume resynchronization can occur from either shadow to master
-or master to shadow.
-.sp
-.LP
-Instantly after the point-in-time is (re-)established (either when the CLI
-prompt returns or the next shell script command is read), the master volume can
-be remounted or the applications using them can be resumed. Also, the shadow
-volume can be mounted and immediately accessed.
-.sp
-.LP
-The \fBiiadm\fR command line utility performs only one action per command
-invocation. Because of this, you cannot combine multiple options, except in
-combination with the following overall command modifiers:
-.RS +4
-.TP
-.ie t \(bu
-.el o
-If no action item is entered, \fBiiadm\fR displays the list of Point-in-Time
-Copy sets (non-suspended) currently configured. If more than one action item,
-or an incorrectly specified action item is entered, \fBiiadm\fR displays the
-specific error message to stderr, followed by a brief usage summary.
-.RE
-.RS +4
-.TP
-.ie t \(bu
-.el o
-For the Point-in-Time Copy options ENABLE (\fB-e\fR), COPY (\fB-c\fR) and
-UPDATE (\fB-u\fR), there are two associated shadow volume selection qualifiers,
-\fB{ind|dep}\fR, that are used to specify the type of Point-in-Time Copy volume
-set to create.
-.RE
-.sp
-.LP
-An independent (\fBind\fR) snapshot causes Point-in-Time Copy software to
-perform a full volume copy operation from the master to the shadow. When the
-copy completes, the shadow volume data is identical to the master volume data
-at the moment that it was established. Create an independent shadow if you
-require two physical copies of the data. An independent shadow volume must be
-the same size or greater than the size of the master volume. Sun recommends
-that the master and shadow volumes be the same size for environments where
-resynchronization from shadow to master is a consideration.
-.sp
-.LP
-A dependent (\fBdep\fR) snapshot causes Point-in-Time Copy software not to
-perform a full volume copy. The resulting shadow volume relies on the master
-volume for all unmodified data blocks, which are not copied until requested.
-Create a dependent shadow when you do not require two physical copies of the
-data. A dependent shadow volume can be either the same size or smaller than the
-master volume. A smaller shadow volume is called a \fBCompact Dependent Shadow
-Volume\fR, and is typically used when the amount of change that occurs to a
-Point-in-Time Copy volume set is small compared to the entire size of the
-master volume.
-.sp
-.LP
-The following syntax allows you to create an exportable independent shadow
-volume in a Sun Cluster environment:
-.sp
-.in +2
-.nf
-# iiadm -ne ind master shadow bitmap
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-An issue arises when using a Compact Dependent Shadow Volume in that its size
-is established at the time that the Point-in-Time Copy volume set is enabled.
-If the amount of change to the entire volume set over the duration of its usage
-exceeds the space allocated for the shadow volume, the shadow volume is marked
-as out of space. It is possible to read from the shadow volume even after it is
-out of space, until a portion of the data for which there was no room is
-requested. Once that happens, the read fails and the shadow volume is marked
-offline.
-.sp
-.LP
-To address this issue, Point-in-Time Copy supports the ability to associate an
-\fBoverflow\fR volume to an existing Point-in-Time Copy dependent volume set.
-Thus, if the size of the Compact Dependent Shadow Volume is too small, or an
-unscheduled amount of change occurs to the volume set, changed data can be
-redirected to the associated overflow volume. To facilitate efficient usage of
-this overflow volume, it can be associated with multiple Point-in-Time Copy
-volume sets on an as-needed basis.
-.SS "Considerations"
-.LP
-Prior to invoking an Point-in-Time Copy \fBenable\fR, \fBcopy\fR or
-\fBupdate\fR operation, Point-in-Time Copy assures that the shadow volume is
-not mounted, to prevent a file system panic from occurring. Also, it is
-suggested that you either unmount or suspend (quiesce) all applications using
-the master volume, for only the instant when the point-in-time snapshot is
-taken. This assures that an atomically consistent point-in-time snapshot is
-taken.
-.sp
-.LP
-It is suggested that, if the master volume was suspended rather than unmounted,
-the new point-in-time shadow volume's integrity be validated using volume
-validation utilities, such as \fBfsck\fR(1M). The reason is that Point-in-Time
-Copy has made a point-in-time copy of a \fBmounted\fR master volume to an
-\fBunmounted\fR shadow volume. During the mounting of the shadow volume, the
-file system detects that it is in the \fBmounted\fR state. Typically this state
-occurs only when a system crashes, so the file system attempts to validate the
-integrity of the volume assuming a system failure occurred, not an
-Point-in-Time Copy.
-.SS "ENVIRONMENT OPTIONS"
-.LP
-The \fBii_bitmap\fR variable in the \fB/usr/kernel/drv/ii.conf\fR configuration
-file determines the bitmap volume operational semantics as follows:
-.sp
-.ne 2
-.na
-\fB\fB0\fR\fR
-.ad
-.RS 13n
-Indicates that the bitmap is maintained in memory only or resume operation.
-.RE
-
-.sp

-.na
-\fB\fB1\fR\fR
-.ad
-.RS 13n
-Indicates that the bitmap is maintained in memory and on disk. This is the
-default value.
-.RE
-
-.sp
-.LP
-If a system failure occurs while using \fBii_bitmap=0\fR, the shadow volume
-might be inconsistent and fast resynchronization would not be possible.
-.sp
-.LP
-If Point-in-Time Copy is used in conjunction with the Network Storage component
-Remote Mirror or in a Sun Cluster, set \fBii_bitmap=1\fR.
-.sp
-.LP
-The \fBii_debug\fR variable in the \fB/usr/kernel/drv/ii.conf\fR configuration
-file determines the amount of information logging that is output to the system
-console \fB/dev/console\fR during Point-in-Time Copy processing.
-.sp

-.RS 4n
-Enable Point-in-Time Copy for the specified master, shadow, and bitmap volumes.
-.sp
-The enable shadow set processing assures that the specified volumes are
-accessible, that the \fIshadow_vol\fR is not mounted, and that the
-\fIbitmap_vol\fR is correctly sized for the type of shadow set being created.
-Additionally, it assures that the volumes are under control of the SV driver (
-if they are not, it puts them there), initializes the bitmap volume, and, if
-the volume set is an independent shadow set, a full copy operation is
-initiated.
-.sp
-On a successful enable, Point-in-Time Copy stores the specified
-\fImaster_vol\fR, \fIshadow_vol\fR and \fIbitmap_vol\fR names, plus the
-enabling type (\fBind\fR or \fBdep\fR), into the Point-in-Time Copy
-configuration store. The configuration store contains all currently configured
-Point-in-Time Copy Volume Sets and their associated configuration attributes.
-(See discussion above on independent and dependent shadow volume semantics.)
-.sp
-\fImaster_vol\fR is the volume from which a point-in-time snapshot is made.
-.sp
-\fIshadow_vol\fR is the volume that contains the point-in-time snapshot.
-.sp
-\fIbitmap_vol\fR is used for tracking differences between the shadow and master
-volumes. When Point-in-Time Copy shadow operations are suspended or resumed,
-the bitmap volume (maintained in kernel memory) can be stored in or retrieved
-from permanent storage. The storage associated with the bitmap volume should be
-as redundant as that of the shadow volume storage.
-.sp
-The \fIshadow_vol\fR name is the name that the Point-in-Time Copy Shadow Set is
-known by for all \fBiiadm\fR options requiring specification of a
-\fIvolume_set\fR name.

-.SH DESCRIPTION
-.sp
-.LP
-The \fB/usr/sbin/sndradm\fR command is the administrative command line
-interface for the Sun StorageTek Availability Suite Remote Mirror software.
-Remote Mirror enables you to replicate disks between different
-physically-separate Sun servers in real time. Remote Mirror is conceptually
-similar to the local disk mirroring scheme of RAID 1 but it performs its
-replication operations over longer distances.
-.sp
-.LP
-If you do not specify a Remote Mirror set (\fIsndr_set\fR) on the command line,
-\fBsndradm\fR operates on all configured Remote Mirror sets.
-.sp
-.LP
-The \fBsndradm\fR command generates an entry in the Availability Suite log
-file, \fB/var/adm/ds.log\fR (see \fBds.log\fR(4)), for all operations except
-print (\fB-p\fR, \fB-P\fR and \fB-i\fR), help (\fB-h\fR), and version
-(\fB-v\fR).
-.SH OPTIONS

-.nf
-\fB/usr/lib/sndrsyncd\fR
-.fi
-
-.SH DESCRIPTION
-.LP
-The \fBsndrsyncd\fR daemon automates update resynchronization after a network
-or machine failure and invokes Point-in-Time Copy copies when needed to protect
-the data volumes being updated during a resynchronization.
-.sp
-.LP
-The daemon is notified by the kernel when a network link being used by Remote
-Mirror goes down and invokes the \fBsndradm\fR(1M) command with the \fB-u\fR
-option to resynchronize all Remote Mirror sets which have autosync switched on
-and are using the network link. See \fBsndradm\fR(1M) for details on how to
-configure autosync for a Remote Mirror set.
-.sp
-.LP
-The daemon is also notified when any Remote Mirror resynchronization starts or
-completes. The daemon takes Point-in-Time Copy snapshots, if configured in the
-Availability Suite configuration file. On a secondary server, the daemon checks
-if a file system is currently mounted on the secondary volume and informs the
-kernel not to allow the synchronization to start if the file system is
-currently mounted.

-.SH DESCRIPTION
-.LP
-The \fBsvadm\fR command controls the Storage Volume (SV) driver by providing
-facilities to enable and disable the SV driver for specified volumes, and to
-dynamically reconfigure the system.
-.SH OPTIONS
-.LP
-If you specify no arguments to an \fBsvadm\fR command, the utility displays the
-list of volumes currently under SV control. \fBsvadm\fR supports the following
-options:
-.sp
-.ne 2
-.na
-\fB\fB-C\fR \fItag\fR\fR
-.ad
-.sp .6
-.RS 4n
-On a clustered node, limits operations to only those volumes belonging to the
-cluster resource group, or disk group name, specified by tag. This option is
-illegal on a system that is not clustered. The special \fItag\fR, \fBlocal\fR,
-can be used to limit operations to only those volumes that cannot switch over
-to other nodes in the cluster.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-d\fR\fR
-.ad
-.sp .6
-.RS 4n
-Disables the SV devices specified on the command line or in the configuration
-file. If \fB-C\fR tag is specified with this option, then the volume should be
-in this cluster disk group.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-e\fR\fR
-.ad
-.sp .6
-.RS 4n
-Enables the SV devices specified on the command line or in the configuration
-file. Details of the volume are saved in the current configuration. See
-\fBdscfg\fR(1M). If \fB-C\fR tag is specified with this option, then the volume
-should be in this cluster disk group.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-f\fR \fIconfig_file\fR\fR
-.ad
-.sp .6
-.RS 4n
-Specifies a configuration file that contains a list of volumes. A command reads
-this volume list and then perform the operation. The format of the
-\fIconfig_file\fR is a simple list of volume pathnames, one per line. Blank
-lines and lines starting with the comment character (#) are ignored.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-h\fR\fR
-.ad
-.sp .6
-.RS 4n
-Displays the \fBsvadm\fR usage summary.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-i\fR\fR
-.ad
-.sp .6
-.RS 4n
-Displays extended status for the volumes currently under SV control.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-r\fR\fR
-.ad
-.sp .6
-.RS 4n
-When a \fIconfig_file\fR is specified, reconfigure the running system to match
-the configuration specified in the \fIconfig_file\fR. When the \fB-C\fR option
-is specified, compare the cluster tag for each volume and change it to
-\fIcluster_tag\fR. If a volume is specified with this option, it is valid only
-to reconfigure the cluster tag associated with the volume. The \fB-e\fR or
-\fB-d\fR options should be used to enable or disable single volumes.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-v\fR\fR
-.ad
-.sp .6
-.RS 4n
-Displays the SV version number.
-.RE
-
-.SH USAGE
-.LP
-When an SV volume is enabled, normal system call access to the device (see
-\fBIntro\fR(2)) is redirected into the StoreEdge architecture software. This
-allows standard applications to use StorageTek features such as Sun StorageTek
-Point-in-Time Copy and Remote Mirror Software.
-.sp
-.LP
-The \fBsvadm\fR command generates an entry in the Availability Suite log file,
-\fB/var/adm/ds.log\fR (see \fBds.log\fR(4)), when performing enable (\fB-e\fR)
-and disable (\fB-d\fR) operations.

-The \fBii\fR device is a control interface for Instant Image devices and
-controls the Instant Image module through the \fBioctl\fR(2) interface.
-.sp
-.LP
-Instant Image is a point-in-time volume copy facility for the Solaris operating
-environment that is administered through the \fBiiadm\fR(1M) command. With
-Instant Image, you can create an independent point-in-time copy of a volume or
-a master volume-dependent point-in-time view.  You can also independently
-access the master and shadow volume for read and write operations. Instant
-Image also lets you update the shadow volume from the master volume or restore
-the master volume from the shadow. (Restore operations to volumes can be full
-or incremental). Instant Image supports fast volume re-synchronization, letting
-you create a new point-in-time volume copy by updating the specified volume
-with only changed data.
-.sp
-.LP
-To create a shadow volume you need a:
-.RS +4
-.TP
-1.
-Master volume to be shadowed.
-.RE
-.RS +4
-.TP
-2.
-Shadow volume where the copy will reside. This volume must be equal to or
-larger than the master volume.
-.RE
-.RS +4
-.TP
-3.
-Administrative bitmap volume or file for tracking differences between the
-shadow and master volumes. The administrative bitmap volume or file must be at
-least 24Kbytes in size and requires 8KBytes for each GByte (or part thereof) of
-master volume size, plus an additional 8KBytes overhead. For example, to shadow
-a 3GByte master volume, the administration volume must be 8KBytes + (3 *
-8KBytes) =32KBytes in size.
-.RE
-.sp
-.LP
-The Instant Image module uses services provided by the SDBC and SD_GEN modules.
-The SV module is required to present a conventional block device interface to
-the storage product interface of the Instant Image, SDBC and SD_GEN modules.
-.sp
-.LP
-When a shadow operation is suspended or resumed, the administration volumes may
-be stored in permanent SDBC storage or loaded and saved to and from kernel
-memory. The ii_bitmap variable in the \fB/kernel/drv/ii.conf\fR configuration
-file determines the administration volume storage type. A value of 0 indicates
-kernel memory, while a value of 1 indicates permanent SDBC storage.  If the
-system is part of a storage products cluster, use the 1 value (permanent
-storage), otherwise use kernel memory (0 value).

-	"sd" cache layer
-	----------------
-#include <sys/sd/sd.h>
-
-The "sd" layer provides a common interface to the functionality
-described below.  It will also allow switching to a direct to disk
-version, so that a new cache module could be loaded.
-The functions are basically the same as those below,
-but named without the leading underscore.
-(ie sd_alloc_buf instead of _sd_alloc_buf)
-
-
-	"sdbc" -- storage device block cache (aka blkc)
-	-----------------------------------------------
-
-#include "uts/sd/sdbc/sd_cache.h"	/* for SDBC interface */
-#include "sys/sd/sd.h"			/* for generic SD interface */
-
-(all interaction is in terms of the buf_handle.
-
-Currently buf_handle is declared as:
-
-#define _SD_MAX_BLKS	64
-#define _SD_MAX_FBAS	(_SD_MAX_BLKS << FBA_SHFT)
-
-typedef struct _sd_buf_handle {
-	int bh_cd;		/* actually bh_buf.sb_cd */
-	int bh_fba_pos;		/* bh_buf.sb_pos */
-	int bh_fba_len;		/* bh_buf.sb_len */
-	int bh_flag;		/* bh_buf.sb_flag */
-	int bh_error;		/* bh_buf.sb_error */
-	_sd_vec_t bh_bufvec[_SD_MAX_BLKS]; /* bh_buf.sb_vec */
-	void (*bh_disconnect_cb)();
-	void (*bh_read_cb)();
-	void (*bh_write_cb)();
-	......
-} _sd_buf_handle_t;
-
-
-typedef struct sd_vec_s {		/* Scatter gather element */
-	unsigned char	*sv_addr;	/* Virtual address of data */
-	unsigned int	sv_vme;		/* VME address of data */
-	int		sv_len;		/* Data length in bytes */
-} sd_vec_t;
-
-The upper level routines should reference only: handle->bh_error,
-handle->bh_bufvec The bh_bufvec is an array of _sd_vec_t with the
-last item in the array having a NULL bufaddr. 
-
-IMPORTANT: The handle should be treated read-only and never be modified.
-
-	1) Multiple accesses to a single file will be supported. 
-	(Side effect: If a process owning cache blocks of a files attempts 
-	to allocate overlapping cache blocks, it will be a 
-	deadlock condition.)
-
-	2) Multiple writes to an allocated block will be supported. It
-	is no longer necessary to free and re-allocate between writes.
-
-	3) _SD_NOBLOCK is equivalent of async_io -- the io will be initiated
-	if required with the call returning _SD_PENDING. A callback 
-	(read or write) will be called at io end action.
-
-	4) Disconnect hints to ckd will be provided by the use of
-	either psema or thread_bind() when io needs to be initiated.
-
-
-NOTE:
-	fba_pos = disk block number, each block being 512 bytes.
-	fba_len = len in disk blocks, each block being 512 bytes.
-		Thus, 512 bytes = 1 fba_len, 1024 = 2 fba_len etc...
-
-Hints:
-	_SD_WRTHRU: write through mode. 
-		This hint can be set on a node, a device or per access.
-	_SD_FORCED_WRTHRU: forced write through (node down or flow control)
-		If this hint is cleared,  when only one node is up, 
-		_sd_uncommit() will not work properly, and a second
-		failure could result in lost data.
-		This is a node hint.
-	_SD_NOCACHE: reuse cache blocks immediately instead of keeping
-		in lru order.
-		This hint can be set on a device or per access.
-
-Interface:
-
-_sd_buf_handle_t *
-_sd_alloc_handle(discon_cb, read_cb, write_cb)
-	void (*discon_cb)();
-	void (*read_cb)();
-	void (*write_cb)();
-
-	The callbacks can be NULL if you do not want any callbacks.
-	Else, the callbacks will be stored in the handle, and will be 
-	called at specific points in the cache. (Its up to  the
-	callback to do what is necessary, including disconnecting
-	from the channel)
-
-	Usage: for better performance, an application could allocate
-	a handle (or as many handles as is required)  upfront and
-	use it later on in the cache calls.
-
-	Not allocating and managing the handles would mean a new
-	handle will be allocated and freed during _sd_alloc_buf
-	and _sd_freebuf.
-	
-int	
-_sd_free_handle(handle)
-	_sd_buf_handle_t *handle;
-
-	Only handles that are allocated through _sd_alloc_handle
-	should be freed with this call.
-	
-int 
-_sd_alloc_buf (cd, fba_pos, fba_len, flag, handle_p)
-	int cd;
-	int fba_pos;
-	int fba_len;
-	int flag;
-	_sd_buf_handle_t **handle_p;  
- 
-	cd = cache descriptor. Results in an error if this node does
-		not own this disk and the other node has not crashed.
-		(ie. requests must be routed to the correct node)
-		(see fault tolerant aspects discussed elsewhere)
- 
-	fba_pos = disk position in multiples of 512 byte blocks.
-	fba_len = length in multiples of 512 bytes blocks.
-		(NOTE: This cannot exceed _SD_MAX_FBAS)
- 
-	flag = None, one or more of the following (described below):
-		_SD_RDBUF | SD_WRBUF | _SD_RDWRBUF | _SD_PINNABLE |
-		_SD_NOBLOCK | _SD_NOCACHE | _SD_WRTHRU
- 
-	handle_p = (*handle_p = handle to be used for this call)
-		If *handle_p == NULL, a new handle will be
-		allocated. _sd_free_buf will free up any handles
-                    allocated in this fashion.
-		NOTE: Handles allocated in this fashion will not have
-			any callbacks registered in them. As such, 
-			_SD_NOBLOCK flag along with a NULL handle would
-			result in the io being lost.
-	
-	return: Error number if > 0
-		possible errors:
-			EINVAL if arguments are incorrect or
-				cache not initialized or
-				device not open.
-			E2BIG if this request is a read and such a large
-			request cannot be currently satisfied. (break up
-			the io or re-issue at a later point)
-			EIO or any other errno that the driver might return.
-		Note: on error, the handle is not active,
-		and also is freed if *handle_p was NULL.
- 
-	if 0 or less, status will be one of:
-	   _SD_DONE: buffer is ready, and ready to be used.
-		(with the blocks valid if _SD_RDBUF is set)
-	   _SD_PENDING: 
-		read callback, if one has been registered in the handle, 
-		will be called to complete this request.
-	   _SD_HIT:  Same as _SD_DONE, read was satisfied by cache,
-		or no blocking required for write buffer.
-
-	Note:	_SD_RDBUF will issue the read if necessary.
-		_SD_WRBUF allocates a network address to reflect to
-			mirror node on _sd_write().
-		~_SD_RDBUF allocates buffers but does NOT pre-read;
-			use _sd_read() to fill in (portions) as req'd.
-
-	Note:	flag == (_SD_RDBUF|_SD_WRTHRU|_SD_NOCACHE) will
-		clear valid bits (that are not dirty) thus read direct
-		from disk, without requiring a hash invalidate.

-
-	returns 0 (_SD_DONE) else errno;
-
-_sd_open(filename, flag)
-	char *filename;
-	int flag;
-
-	returns a cache descriptor, or negative error number.
-	Typically use _sd_attach_cd(cd) before accessing the device.
-	Note: if devices is already open, it returns the same cache descriptor.
-	Currently there is no reference count; so one _sd_close() closes
-	the cache descriptor (in all contexts).
-
-_sd_close(cd)
-	int cd;
-	Similar to _sd_detach_cd below.
-	Note: intended to be called when terminating the cache; and not during
-	normal operation.  No reference count (see above).
-	Returns: 0 success, EIO.
-
-_sd_detach_cd(cd)
-	re-reflect any pinned blocks to the other side,
-	or wait for writes to flush; and invalidate that device's hash entries,
-	and relinquish device responsibility.
-	Returns: 0 success, EIO, EAGAIN.
-
-_sd_attach_cd(cd)
-	If device has pinned blocks then scan for and re-pin those blocks
-	(same idea as "node recovery" process, but per-device);
-	and assert device responsibility.
-
-_sd_notify_all_pin(cd)
-	rescan list of failed blocks and re-issue the pinned callback to
-	simulation. 
-
-
-_sd_register_pinned(func)
-	void (*func)();
-    callback (*func)(cd, fba_pos, fba_len) when disk write fails,
-    and _SD_PENDING was specified on alloc. 
-
-_sd_register_unpinned(func)
-	void (*func)();
-    callback (*func)(cd, fba_pos, fba_len) when data previously pinned
-    is successfully written to disk.
-
-_sd_register_down(func)
-	void (*func)();
-    callback (*func)() when health monitor detects the other node went down.
-
-_sd_set_hint(cd, hint) 
-_sd_clear_hint(cd, hint)
-_sd_get_cd_hint(cd, &hint)
-_sd_set_node_hint(hint)
-_sd_clear_node_hint(hint)
-_sd_get_node_hint(&hint)
-
-    where hint is _SD_NOCACHE and _SD_WRTHRU. (Write through being synchronous
-	write and will be the default if the second node dies.)
-
-   _SD_NOCACHE: hint indicating that the current access need not be 
-	cached for later consumption.
-
-
-_sd_discard_pinned(cd, fba_pos, fba_len)
-	call from ckd into cache, called when data that was earlier 
-	on pinned can be discarded from the cache.
-
-	returns: 0 or error.
-	(error = EINVAL if the discard could not be done)
-
-(note: there is an inherent race between the unpinned callback and 
-_sd_discard_pinned which could put the data on disk in an inconsistent
-state)
-
-
-Failover support:
-
-The Nodedown callback will be called, if one has been registered. This 
-will happen as soon as the other node has been detected to have gone down, 
-or when the cache is disabled on the other node.
-
-The amount of time to for this callback to happen after the node goes down
-is not deterministic.
-
-Access to a mirror node's devices is only valid from the point the 
-nodedown callback is called till the other node is determined to be back
-in operation.
-
-Access to mirror node's devices while recovery is in progress will 
-block the access till the recovery is complete.

-TITLE:	Kstats Specification for SDBC
-
-DATE:	10-28-2002
-
-AUTHOR:	Chris Juhasz (chris.juhasz@sun.com)
-
-LOCATION: src/uts/common/ns/sdbc/cache_kstats_readme.txt
-================================================================================
-
-The existing sd_stat cache statistical reporting mechanism has been expanded  
-with the kstat library reporting mechanism. The existing mechanism will probably
-eventually be phased out.  In general the statistics have fallen 
-into two general categories - "global" and "cd." The global stats reflect gross 
-behavior over all cached volumes, while "cd" stats reflect behavior particular 
-to each cached volume (or cache descriptor).
-
-The sdbc module makes use of two types of kstats.  For generic statistic
-reporting, "regular" kstat_named_t type kstats are used.  For timing-specific
-reporting, sdbc relies on the kstat_io_t type.
-
-For more information on kstats, see [1] in the References section.
-
-1.0 NAMING:
-===========
-The names for the sdbc kstats are defined in src/uts/common/ns/sdbc/sd_misc.h
-
-2.0 REGULAR KSTATS:
-===================
-The following are kstats of type kstat_named_t, used to gather generic
-statistics.
-
-These make use of the original statistics gathering mechanism for sdbc, 
-_sd_stats_t and _sd_shared_t structs, defined in 
-src/uts/common/ns/sdbc/sd_bcache.h.  The _sd_stats_t structure tracks 
-statistics that are global to the entire cache, while the _sd_shared_t struct 
-is used to track statistics particular to a cache descriptor (cd). 
-
-2.1 GLOBAL KSTATS:
-~~~~~~~~~~~~~~~~~~
-This global kstat represents statistics which reflect the state of the entire
-cache, summed over all cache descriptors.
-
-2.1.1 Field Definitions:
-------------------------
-The "global" kstat corresponds to fields in the _sd_stats_t structure.  The
-following table maps the name of the kstat field to its equivalent field in
-the _sd_stats_t structure, also providing a description where appropriate.
- 
-KSTAT FIELD		_sd_stats_t	DESCRIPTION
------------		-----------	-----------
-sdbc_count		st_count	- number of opens for device
-sdbc_loc_count		st_loc_count	- number of open devices
-sdbc_rdhits		st_rdhits	- number of read hits
-sdbc_rdmiss		st_rdmiss	- number of read misses
-sdbc_wrhits		st_wrhits	- number of write hits
-sdbc_wrmiss		st_wrmiss	- number of write misses
-sdbc_blksize		st_blksize	- cache block size (in bytes)

-sdbc_lru_req		st_lru_req
-
-sdbc_wlru_inq		st_wlru_inq	- number of write blocks
-sdbc_cachesize		st_cachesize	- cache size (in bytes)
-sdbc_numblocks		st_numblocks	- cache blocks
-sdbc_num_shared		MAXFILES*2	- number of shared structures (one for
-					  each cached volume)
-					  This number dictates the maximum 
-					  index size for shared stats and 
-					  names given below.
-sdbc_destaged		st_destaged	- number of bytes destaged to disk
-					  (flushed from the cache to disk).
-sdbc_wrcancelns		st_wrcancelns	- number of write cancellations
-					  (writes to cached blocks that are 
-					  already dirty).
-sdbc_nodehints		---		- node hints (such as wrthru/nowrthru)
-
-All fields are read-only and are of type KSTAT_DATA_ULONG. Note that the
-"sdbc_wrcancelns" and "sdbc_destaged" are new, and have also been added to the
-_sd_stats_t struct.
-
-2.1.2 Naming characteristics:
------------------------------
-module:		SDBC_KSTAT_MODULE	"sdbc"  
-class:		SDBC_KSTAT_CLASS	"storedge"
-name:		SDBC_KSTAT_GSTATS	"global"

-
-
-2.2 KSTATS (PER CACHE DESCRIPTOR):
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-These "cd" kstats present statistics which reflect the state of a single cache 
-descriptor.  One of these kstats exists for each open cache descriptor.
-
-2.2.1 Field Definitions:
-------------------------
-The "cd" kstats correspond to fields in the _sd_shared_t structure.  The
-following table maps the name of the kstat field to its equivalent field in
-the _sd_shared_t structure, also providing a description where appropriate.
-

-
-All fields are read-only kstat_named_t kstats, with data type KSTAT_DATA_ULONG.
-The instance number of the kstat corresponds to the cache descriptor number.   
-Note that the "sdbc_wrcancelns" and "sdbc_destaged" are new, and have also 
-been added to the _sd_shared_t struct.
-
-2.2.2 Naming characteristics:
------------------------------
-module:		SDBC_KSTAT_MODULE	"sdbc"  
-class:		SDBC_KSTAT_CLASS	"storedge"
-name:		SDBC_KSTAT_CDSTATS	"cd%d"	(%d = < cd number >)
-instance #:	< cache descriptor number > 
-
-3.0 I/O KSTATS:
-===============
-The sdbc module now contains kstats of type kstat_io_t.  These are used to
-track timing through the cache.  As with the "regular" kstats, sdbc tracks
-global statistics, as well as those per cache descriptor.  Since kstat_io_t
-is a built-in kstat type, all are defined the same way. 
-
-3.0.1 Time-Gathering:
----------------------
-These kstat_io_t types provide two built-in time-gathering mechanisms, which it 
-refers to as "waitq" and "runq," where "waitq" is intended to be interpreted 
-as the amount of time a request spends in its pre-service state, and "runq" the 
-amount of time a request spends in its service state.  Transitions to the
-runq and the waitq must be  made via built-in functions, such as
-kstat_runq_enter() and kstat_runq_exit().  The relevant fields in the 
-kstat_io_t structure should not be considered explicitly.  (See comment below).
-The iostat(1M) utility may be used to gather timing-related information
-collected through this mechanism.
-
-Please note that sdbc does not use waitq.
-sdbc uses runq as follows:
-
-An I/O request transitions to the runq (both global, and per-cd) upon entering 
-the cache through _sd_read(), _sd_write(), or _sd_alloc_buf().  It
-transitions off the runq after the request has been serviced, either by the 
-cache, or as the result of disk I/O.  Thus, this allows a user to track the
-total time spent in the cache, which includes disk I/O time.
-
- 
-3.0.2 kstat_io_t Fields:
-------------------------
-These I/O kstats include the following fields:
-
-        u_longlong_t    nread;          /* number of bytes read */
-        u_longlong_t    nwritten;       /* number of bytes written */
-        uint_t          reads;          /* number of read operations */
-        uint_t          writes;         /* number of write operations */
-
-# The following fields are automatically updated by the built-in
-# kstat_waitq_enter(), kstat_waitq_exit(), kstat_runq_enter() and
-# kstat_runq_exit() functions.
-
-	hrtime_t wtime;		/* cumulative wait (pre-service) time */
-	hrtime_t wlentime;	/* cumulative wait length*time product */
-	hrtime_t wlastupdate;	/* last time wait queue changed */
-	hrtime_t rtime;		/* cumulative run (service) time */
-	hrtime_t rlentime;	/* cumulative run length*time product */
-	hrtime_t rlastupdate;	/* last time run queue changed */
-
-	uint_t	wcnt;		/* count of elements in wait state */
-	uint_t	rcnt;		/* count of elements in run state */
-
-For more information, refer to [2] in the References section. 
-
-3.1 GLOBAL IO KSTATS:
-~~~~~~~~~~~~~~~~~~~~~
-sdbc includes "global" I/O kstats which track the timings through the cache as 
-a whole, taking into account all cache descriptors.  The fields definitions
-are built-in, as explained above.
-
-3.1.1 Naming characteristics:
------------------------------
-module:		SDBC_KSTAT_MODULE	"sdbc"  
-class:					"disk"
-name:		SDBC_IOKSTAT_GSTATS	"gsdbc"
-instance #:	0
-
-3.2 IO KSTATS (PER CACHE DESCRIPTOR):
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-These "cd" I/O kstats present statistics which reflect the state of a single 
-cache descriptor.  One of these I/O kstats exists for each open cache 
-descriptor. The fields definitions are built-in, as explained above.
-
-3.2.1 Naming characteristics:
------------------------------
-module:		SDBC_KSTAT_MODULE	"sdbc"  
-class:					"disk"
-name:		SDBC_IOKSTAT_STATS	"sdbc%d" (%d = < cd number >) 
-instance #:	< cache descriptor number > 
-
-4.0 DYNMEM KSTATS:
-==================
-The sdbc module also a "regular" kstat to track dynamic memory
-allocation in the cache.  These are "global" statistics.
-
-Its fields can be divided logically between behavior variables, and statistical 
-variable
-
-4.1 Field Definitions: 
-~~~~~~~~~~~~~~~~~~~~~~
-
-4.1.1 Behavior Variables:
--------------------------
-sdbc_monitor_dynmem --- D0=monitor thread shutdown in the console window
-                        D1=print deallocation thread stats to the console 
-                        window
-                        D2=print more deallocation thread stats to the console 
-                        window
-                        (usage: setting a value of 6 = 2+4 sets D1 and D2)
-sdbc_max_dyn_list ----- 1 to ?: sets the maximum host/parasite list length
-                        (A length of 1 prevents any multipage allocations from 
-                        occuring and effectively removes the concept of 
-                        host/parasite.)
-sdbc_cache_aging_ct1 -- 1 to 255: fully aged count (everything but meta and 
-			holdover)

-TITLE: Dynamic Memory Implementation Overview
-
-DATE:  10/13/2000
-
-AUTHOR: Jim Guerrera (james.guerrera@east)
-
-
-1.0 Dynamic Memory Implementation in the SCM Module
-
-The system memory allocation required by the Storage Cache Manager (SCM)
-has been modified to more fully conform to the requirements of the Solaris
-OS. The previous implementation required that the total memory requirements
-of the package be allocated 'up front' during bootup and was never released. 
-The current implementation performs 'on demand' allocations at the time
-memory is required in a piecemeal manner. In addition the requisitioned
-memory will be released back to the system at some later time.
-
-2.0 Implementation
-
-2.1 Memory Allocation
-
-The memory allocation involves modifications primarily to sd_alloc_buf()
-in module sd_bcache.c. When a request is received for cache and system 
-resources it is broken down and each piece catagorized both as an
-independent entity and as a member of a group with close neighbors. Cache
-resources comprise cache control entries (ccent), write control entries 
-(wctrl for FWC support) and system memory. The current allocation algorithim
-for ccent and wrctl remains the same. The memory allocation has been modified
-and falls into two general catagories - single page and multi-page 
-allocations.
-
-2.1.1 A single page allocation means exactly that  - the ccent points to and
-owns one page of system memory. If two or more ccent are requisitioned to 
-support the caching request then only the first entry in the group actually 
-owns the the allocated memory of two or more pages. The secondary entries 
-simply point to page boundaries within this larger piece of contiguous memory.
-The first entry is termed a host and the secondaries are termed parasites. 
-
-The process for determining what is a host, a parasite or anything else is 
-done in three phases. Phase one simply determines whether the caching request
-references a disk area already in cache and  marks it as such. If it is not
-in cache it is typed as eligible - i.e. needing memory allocation. Phase
-two scans this list of typed cache entries and based on immediate neighbors
-is catagorized as host, pest or downgraded to other. A host can only exist 
-if there is one or more eligible entries immediately following it and it 
-itself either starts the list or immediately follows a non-eligible entry. 
-If either condition proves false the catagory remains as eligible (i.e. 
-needs memory allocation) but the type is cleared to not host (i.e. other). 
-The next phase is simply a matter of scanning the cache entry list and 
-allocating multipage memory for hosts, single page entries for others or 
-simply setting up pointers in the parasitic entries into it's corresponding
-host multipage memory allocation block.
-
-2.1.2 The maximum number of parasitic entries following a host memory 
-allocation is adjustable by the system administrator. The details of this 
-are under the description of the KSTAT interface (Sec 3.0).
-
-2.2 Memory Deallocation
-
-Memory deallocation is implemented in  sd_dealloc_dm() in module sd_io.c. 
-This possibly overly complicated routine works as follows:
-
-In general the routine sleeps a specified amount of time then wakes and 
-examines the entire centry list. If an entry is available (i.e. not in use 
-by another thread and has memory which may be deallocated) it takes 
-possession and ages the centry by one tick. It then determines if the 
-centry has aged sufficiently to have its memory deallocated and for it to 
-be placed at the top of the lru.
-
-2.3 There are two general deallocation schemes in place depending on 
-whether the centry is a single page allocation centry or it is a member 
-of a host/parasite multipage allocation chain.
-
-2.3.1 The behavior for a single page allocation centry is as follows:
-
-If the given centry is selected as a 'holdover' it will age normally 
-however at full aging it will only be placed at the head of the lru. 
-It's memory will not be deallocated until a further aging level has 
-been reached. The entries selected for this behavior are governed by 
-counting the number of these holdovers in existence on each wakeup 
-and comparing it to a specified percentage. This comparision is always 
-one cycle out of date and will float in the relative vicinity of the 
-specified number.
-
-In addition there is a placeholder for centries identified as 'sticky 
-meta-data' with its own aging counter. It operates exactly as the holdover 
-entries as regards to aging but is absolute - i.e. no percentage governs 
-the number of such entries. 
-
-2.3.2 The percentage and additional aging count are adjustable by the 
-system administrator. The details of this are under the description of 
-the KSTAT interface (Sec. 3.0).
-
-2.3.3 The behavior for a host/parasite chain is as follows:
-
-The host/parasite subchain is examined. If all entries are fully aged the 
-entire chain is removed - i.e memory is deallocated from the host centry 
-and all centry fields are cleared and each entry requeued on to the lru.
-
-There are three sleep times and two percentage levels specifiable by the 
-system administrator. A meaningful relationship between these variables 
-is:
-
-sleeptime1 >= sleeptime2 >= sleeptime2 and
-100% >= pcntfree1 >= pcntfree2 >= 0%
-
-sleeptime1 is honored between 100% free and pcntfree1. sleeptime2 is 
-honored between pcntfree1 and pcntfree2. sleeptime3 is honored between 
-pcntfree2 and 0% free. The general thrust here is to automatically 
-adjust sleep time to centry load. 
-
-In addition  there exist an accelerated aging flag which mimics hysterisis 
-behavior. If the available centrys fall between pcntfree1 and pcntfree2 
-an 8 bit counter is switched on. The effect is to keep the timer value 
-at sleeptime2 for 8 cycles even if the number available cache entries 
-drifts above pcntfree1. If it falls below pcntfree2 an additional 8 bit 
-counter is switched on. This causes the sleep timer to remain at sleeptime3 
-for at least 8 cycles even if it floats above pcntfree2 or even pcntfree1. 
-The overall effect of this is to accelerate the release of system resources
-under what the thread thinks is a heavy load as measured by the number of 
-used cache entries.
-
-3.0 Dynamic Memory Tuning
-
-A number of behavior modification variables are accessible via system calls 
-to the kstat library. A sample program exercising the various features can 
-be found in ./src/cmd/ns/sdbc/sdbc_dynmem.c. In addition the behavior variable 
-identifiers can be placed in the sdbc.conf file and will take effect on bootup.
-There is also a 
-number of dynamic memory statistics available to gauge its current state.
-
-3.1 Behavior Variables
-
-sdbc_monitor_dynmem --- D0=monitor thread shutdown in the console window
-                        D1=print deallocation thread stats to the console 
-                        window
-                        D2=print more deallocation thread stats to the console 
-                        window
-                        (usage: setting a value of 6 = 2+4 sets D1 and D2)
-sdbc_max_dyn_list ----- 1 to ?: sets the maximum host/parasite list length
-                        (A length of 1 prevents any multipage allocations from 
-                        occuring and effectively removes the concept of 
-                        host/parasite.)
-sdbc_cache_aging_ct1 -- 1 to 255: fully aged count (everything but meta and 
-			holdover)
-sdbc_cache_aging_ct2 -- 1 to 255: fully aged count for meta-data entries
-sdbc_cache_aging_ct3 -- 1 to 255: fully aged count for holdovers
-sdbc_cache_aging_sec1 - 1 to 255: sleep level 1 for 100% to pcnt1 free cache 
-			entries
-sdbc_cache_aging_sec2 - 1 to 255: sleep level 2 for pcnt1 to pcnt2 free cache 
-			entries
-sdbc_cache_aging_sec3 - 1 to 255: sleep level 3 for pcnt2 to 0% free cache 
-			entries
-sdbc_cache_aging_pcnt1- 0 to 100: cache free percent for transition from 
-			sleep1 to sleep2
-sdbc_cache_aging_pcnt2- 0 to 100: cache free percent for transition from 
-			sleep2 to sleep3
-sdbc_max_holds_pcnt --- 0 to 100: max percent of cache entries to be maintained 
-			as holdovers
-
-3.2 Statistical Variables
-
-Cache Stats (per wake cycle) (r/w):
-sdbc_alloc_ct --------- total allocations performed
-sdbc_dealloc_ct ------- total deallocations performed
-sdbc_history ---------- current hysterisis flag setting
-sdbc_nodatas ---------- cache entries w/o memory assigned
-sdbc_candidates ------- cache entries ready to be aged or released
-sdbc_deallocs --------- cache entries w/memory deallocated and requeued
-sdbc_hosts ------------ number of host cache entries
-sdbc_pests ------------ number of parasitic cache entries
-sdbc_metas ------------ number of meta-data cache entries
-sdbc_holds ------------ number of holdovers (fully aged w/memory and requeued)
-sdbc_others ----------- number of not [host, pests or metas]
-sdbc_notavail --------- number of cache entries to bypass (nodatas+'in use by 
-                        other processes')
-sdbc_process_directive- D0=1 wake thread
-                        D1=1 temporaily accelerate aging (set the hysterisis
-                        flag)
-sdbc_simplect --------- simple count of the number of times the kstat update 
-			routine has been called          
-
-
-3.3 Range Checks and Limits
-
-Only range limits are checked. Internal inconsistencies are not checked 
-(e.g. pcnt2 > pcnt1). Inconsistencies won't break the system you just won't 
-get meaningful behavior. 
-
-The aging counter and sleep timer limits are arbitrarily limited to a byte 
-wide counter. This can be expanded. However max'ing the values under the 
-current implementation yields about 18 hours for full aging.
-
-3.4 Kstat Lookup Name
-
-The kstat_lookup() module name is "sdbc:dynmem" with an instance of 0.
-
-3.5 Defaults
-
-Default values are:
-sdbc_max_dyn_list = 8
-sdbc_monitor_dynmem = 0
-sdbc_cache_aging_ct1 = 3
-sdbc_cache_aging_ct2 = 3
-sdbc_cache_aging_ct3 = 3
-sdbc_cache_aging_sec1 = 10
-sdbc_cache_aging_sec2 = 5
-sdbc_cache_aging_sec3 = 1
-sdbc_cache_aging_pcnt1 = 50
-sdbc_cache_aging_pcnt2 = 25
-sdbc_max_holds_pcnt = 0
-
-To make the dynmem act for all intents and purposes like the static model 
-beyond the inital startup the appropriate values are:
-sdbc_max_dyn_list = 1,
-sdbc_cache_aging_ct1/2/3=255,
-sdbc_cache_aging_sec1/2/3=255
-The remaining variables are irrelevant.
-
-4.0 KSTAT Implementation for Existing Statistics
-
-The existing cache statistical reporting mechanism has been replaced by 
-the kstat library reporting mechanism. In general the statistics fall into 
-two general catagories - global and shared. The global stats reflect gross 
-behavior over all cached volumes and shared reflects behavior particular 
-to each cached volume.
-
-4.1 Global KSTAT lookup_name
-
-The kstat_lookup() module name is "sdbc:gstats" with an instance of 0. The 
-identifying ascii strings and associated values matching the sd_stats driver 
-structure are:
-
-sdbc_dirty -------- net_dirty
-sdbc_pending ------ net_pending
-sdbc_free --------- net_free
-sdbc_count -------- st_count		- number of opens for device
-sdbc_loc_count ---- st_loc_count	- number of open devices
-sdbc_rdhits ------- st_rdhits		- number of read hits
-sdbc_rdmiss ------- st_rdmiss		- number of read misses
-sdbc_wrhits ------- st_wrhits		- number of write hits
-sdbc_wrmiss ------- st_wrmiss		- number of write misses
-sdbc_blksize ------ st_blksize		- cache block size
-sdbc_num_memsize -- SD_MAX_MEM		- number of defined blocks 
-					  (currently 6)
-To find the size of each memory blocks append the numbers 0 to 5 to 
-'sdbc_memsize'.
-sdbc_memsize0 ----- local memory
-sdbc_memsize1 ----- cache memory
-sdbc_memsize2 ----- iobuf memory
-sdbc_memsize3 ----- hash memory
-sdbc_memsize4 ----- global memory
-sdbc_memsize5 ----- stats memory
-sdbc_total_cmem --- st_total_cmem	- memory used by cache structs
-sdbc_total_smem --- st_total_smem	- memory used by stat  structs 
-sdbc_lru_blocks --- st_lru_blocks
-sdbc_lru_noreq ---- st_lru_noreq
-sdbc_lru_req ------ st_lru_req
-sdbc_num_wlru_inq - MAX_CACHE_NET	- number of net (currently 4)
-To find the size of the least recently used write cache per net append 
-the numbers 0-3 to sdbc_wlru_inq
-sdbc_wlru_inq0 ---- net 0
-sdbc_wlru_inq1 ---- net 1
-sdbc_wlru_inq2 ---- net 2
-sdbc_wlru_inq3 ---- net 3
-sdbc_cachesize ---- st_cachesize	- cache size
-sdbc_numblocks ---- st_numblocks	- cache blocks
-sdbc_num_shared --- MAXFILES*2		- number of shared structures (one for
-					  each cached volume)
-					  This number dictates the maximum 
-					  index size for shared stats and 
-					  names given below.
-sdbc_simplect ----- simple count of the number of times the kstat update routine
-		    has been called
-
-All fields are read only.
-
-
-4.2 Shared Structures KSTAT lookup_name
-
-The kstat_lookup() module name is "sdbc:shstats" and "sdbc:shname" both with 
-an instance of 0. The identifying ascii strings and associated values matching 
-the sd_shared driver structure are:
-
-sdbc:shstats module
-sdbc_index ------- structure index number 
-sdbc_alloc ------- sh_alloc		- is this allocated?
-sdbc_failed ------ sh_failed		- Disk failure status (0=ok,1= /o error
-						,2= open failed)
-sdbc_cd ---------- sh_cd		- the cache descriptor. (for stats)
-sdbc_cache_read -- sh_cache_read	- Number of bytes read from cache
-sdbc_cache_write - sh_cache_write	- Number of bytes written  to cache
-sdbc_disk_read --- sh_disk_read		- Number of bytes read from disk 
-sdbc_disk_write -- sh_disk_write	- Number of bytes written  to disk
-sdbc_filesize ---- sh_filesize		- Filesize
-sdbc_numdirty ---- sh_numdirty		- Number of dirty blocks
-sdbc_numio ------- sh_numio		- Number of blocks on way to disk
-sdbc_numfail ----- sh_numfail		- Number of blocks failed
-sdbc_flushloop --- sh_flushloop		- Loops delayed so far
-sdbc_flag -------- sh_flag		- Flags visible to user programs 
-sdbc_simplect ---- simple count of the number of times the kstat update routine
-		   has been called
-
-sdbc:shname module
-read in as raw bytes and interpreted as a nul terminated assci string.
-
-These two modules operate hand in hand based on information obtained from the
-"sdbc:gstats" module. "sdbc:gstats - sdbc_num_shared" gives the maximum number
-possible of shared devices. It does not tell how many devices are actually 
-cached - just the maximum possible. In order to determine the number present 
-and retrieve the statistics for each device the user must:
-
-1. open and read "sdbc:shstats" 
-2. set the index "sdbc_index" to a starting value (presumably 0)
-3. write the kstat module ( the only item in the module is sdbc_index)
-
-What this does is set a starting index for all subsequent reads. 
-
-4. to get the device count and associated statistics the user now simply 
-reads each module "sdbc:shstats" and "sdbc:shname" as a group repeatedly - 
-the index will auto increment
-
-To reset the index set "sdbc:shstats - sdbc_index" to the required value 
-and write the module.
-
-The first entry returning a nul string to "sdbc:shname" signifies no more 
-configured devices.

- * This complicated - possibly overly complicated routine works as follows:
- * In general the routine sleeps a specified amount of time then wakes and
- * examines the entire centry list. If an entry is avail. it ages it by one
- * tick else it clears the aging flag completely. It then determines if the
- * centry has aged sufficiently to have its memory deallocated and for it to
- * be placed at the top of the lru.
- *
- * There are two deallocation schemes in place depending on whether the
- * centry is a standalone entry or it is a member of a host/parasite chain.
- *
- * The behavior for a standalone entry is as follows:
- * If the given centry is selected it will age normally however at full
- * aging it will only be placed at the head of the lru. It's memory will
- * not be deallocated until a further aging level has been reached. The
- * entries selected for this behavior are goverend by counting the number
- * of these holdovers in existence on each wakeup and and comparing it
- * to a specified percentage. This comparision is always one cycle out of
- * date and will float in the relative vicinity of the specified number.
- *
- * The behavior for a host/parasite chain is as follows:
- * The chain is examined. If all entries are fully aged the entire chain
- * is removed - ie mem is dealloc. from the host entry and all memory ref.
- * removed from the parasitic entries and each entry requeued on to the lru.
- *
- * There are three delay timeouts and two percentage levels specified. Timeout
- * level 1 is honored between 100% free and pcnt level 1. Timeout level 2 is
- * honored between pcnt level 1 and pcnt level 2, Timeout level 3 is
- * honored between pcnt level 2 and 0% free. In addition there exist an
- * accelerated
- * aging flag which mimics hysterisis behavior. If the available centrys fall
- * between pcnt1 and pcnt2 an 8 bit counter is switched on. The effect is to
- * keep the timer value at timer level 2 for 8 cycles even if the number
- * available cache entries drifts above pcnt1. If it falls below pcnt2 an
- * additional 8 bit counter is switched on. This causes the sleep timer to
- * remain at timer level 3 for at least 8 cycles even if it floats above
- * pcnt2 or even pcnt1. The effect of all this is to accelerate the release
- * of system resources under a heavy load.
- *
- * All of the footwork can be stubbed out by a judicious selection of values
- * for the times, aging counts and pcnts.
- *
- * All of these behavior parameters are adjustable on the fly via the kstat
- * mechanism. In addition there is a thread wakeup msg available through the
- * same mechanism.

- * Storage Volume Character and Block Driver (SV)
- *
- * This driver implements a simplistic /dev/{r}dsk/ interface to a
- * specified disk volume that is otherwise managed by the Prism
- * software.  The SV driver layers itself onto the underlying disk
- * device driver by changing function pointers in the cb_ops
- * structure.
- *
- * CONFIGURATION:
- *
- * 1. Configure the driver using the svadm utility.
- * 2. Access the device as before through /dev/rdsk/c?t?d?s?
- *
- * LIMITATIONS:
- *
- * This driver should NOT be used to share a device between another
- * DataServices user interface module (e.g., STE) and a user accessing
- * the device through the block device in O_WRITE mode.  This is because
- * writes through the block device are asynchronous (due to the page
- * cache) and so consistency between the block device user and the
- * STE user cannot be guaranteed.
- *
- * Data is copied between system struct buf(9s) and nsc_vec_t.  This is
- * wasteful and slow.
