  12 DESCRIPTION
  13        To open a device without checking if the vtoc is valid, use the
  14        O_NDELAY flag.  When the device is opened using O_NDELAY, the first
  15        read or write to the device that happens after the open results in the
  16        label being read if the label is not currently valid. Once read, the
  17        label remains valid until the last close of the device. Except for
  18        reading the label, O_NDELAY has no impact on the driver.
  19 
  20    SPARC
  21        The sd SCSI and SCSI/ATAPI driver supports embedded SCSI-2 and
  22        CCS-compatible SCSI disk and CD-ROM drives, ATAPI  2.6
  23        (SFF-8020i)-compliant CD-ROM drives, SFF-8090-compliant SCSI/ATAPI DVD-
  24        ROM drives, IOMEGA SCSI/ATAPI ZIP drives, SCSI JAZ drives, and USB mass
  25        storage devices (refer to scsa2usb(7D)).
  26 
  27 
  28        To determine the disk drive type, use the SCSI/ATAPI inquiry command
  29        and read the volume label stored on block 0 of the drive. (The volume
  30        label describes the disk geometry and partitioning and must be present
  31        for the disk to be mounted by the system.) A volume label is not
  32        required for removable, re-writable or read-only media.
  33 
  34    x86 Only
  35        The sddriver supports embedded SCSI-2 and CCS-compatible SCSI disk and
  36        CD-ROM drives, ATAPI 2.6 (SFF-8020i)-compliant CD-ROM drives,
  37        SFF-8090-compliant SCSI/ATAPI DVD-ROM drives, IOMEGA SCSI/ATAPI ZIP
  38        drives, and SCSI JAZ drives.
  39 
  40 
  41        The x86 BIOS legacy requires a master boot record (MBR) and fdisk table
  42        in the first physical sector of the bootable media. If the x86 hard
  43        disk contains a Solaris disk label, it is located in the second
  44        512-byte sector of the FDISK partition.
  45 
  46 DEVICE SPECIAL FILES
  47        Block-files access the disk using normal buffering mechanism and are
  48        read-from and written-to without regard to physical disk records. A raw
  49        interface enables direct transmission between the disk and the user's
  50        read or write buffer. A single read or write call usually results in a
  51        single I/O operation, therefore raw I/O is more efficient when many
  52        bytes are transmitted.  Block files names are found in /dev/dsk; raw
  53        file names are found in /dev/rdsk.
  54 
  55 
  56        I/O requests to the raw device must be aligned on a 512-byte
  57        (DEV_BSIZE) boundary and all I/O request lengths must be in multiples
  58        of 512 bytes.  Requests that do not meet these requirements will
  59        trigger an EINVAL error. There are no alignment or length restrictions
  60        on I/O requests to the block device.
  61 
  62 CD-ROM DRIVE SUPPORT
  63        A CD-ROM disk is single-sided and contains approximately 640 megabytes
  64        of data or 74 minutes of audio. When the CD-ROM is opened, the eject
  65        button is disabled to prevent manual removal of the disk until the last
  66        close() is called.  No volume label is required for a CD-ROM. The disk
  67        geometry and partitioning information are constant and never change. If
  68        the CD-ROM contains data recorded in a Solaris-aware file system
  69        format, it can be mounted using the appropriate Solaris file system
  70        support.
  71 
  72 DVD-ROM DRIVE SUPPORT
  73        DVD-ROM media can be single or double-sided and can be recorded upon
  74        using a single or double layer structure. Double-layer media provides
  75        parallel or opposite track paths. A DVD-ROM can hold from between 4.5
  76        Gbytes and 17 Gbytes of data, depending on the layer structure used for
  77        recording and if the DVD-ROM is single or double-sided.
  78 
  79 
  80        When the DVD-ROM is opened, the eject button is disabled to prevent the
  81        manual removal of a disk until the last close() is called. No volume
  82        label is required for a DVD-ROM. If the DVD-ROM contains data recorded
  83        in a Solaris-aware file system format, it can be mounted using the
  84        appropriate Solaris file system support.
  85 
  86 ZIP/JAZ DRIVE SUPPORT
  87        ZIP/JAZ media provide varied data capacity points; a single JAZ drive
  88        can store up to 2 GBytes of data, while a ZIP-250 can store up to
  89        250MBytes of data. ZIP/JAZ drives can be read-from or written-to using
  90        the appropriate drive.
  91 
  92 
  93        When a ZIP/JAZ drive is opened, the eject button is disabled to prevent
  94        the manual removal of a disk until the last close() is called. No
  95        volume label is required for a ZIP/JAZ drive. If the ZIP/JAZ drive
  96        contains data recorded in a Solaris-aware file system format, it can be
  97        mounted using the appropriate Solaris file system support.
  98 
  99 DEVICE STATISTICS SUPPORT
 100        Each device maintains I/O statistics for the device and for partitions
 101        allocated for that device. For each device/partition, the driver
 102        accumulates reads, writes, bytes read, and bytes written. The driver
 103        also initiates hi-resolution time stamps at queue entry and exit points
 104        to enable monitoring of residence time and cumulative residence-length
 105        product for each queue.
 106 
 107 
 108        Not all device drivers make per-partition IO statistics available for
 109        reporting. sd and ssd(7D) per-partition statistics are enabled by
 110        default but may disabled in their configuration files.

 167 CONFIGURATION
 168        The sd driver can be configured by defining properties in the sd.conf
 169        file. The sd driver supports the following properties:
 170 
 171        enable-partition-kstats
 172                                   The default value is 1, which causes
 173                                   partition IO statistics to be maintained.
 174                                   Set this value to zero to prevent the driver
 175                                   from recording partition statistics. This
 176                                   slightly reduces the CPU overhead for IO,
 177                                   mimimizes the amount of sar(1) data
 178                                   collected and makes these statistics
 179                                   unavailable for reporting by iostat(1M) even
 180                                   though the -p/-P option is specified.
 181                                   Regardless of this setting, disk IO
 182                                   statistics are always maintained.
 183 
 184 
 185        qfull-retries
 186                                   The supplied value is passed as the qfull-
 187                                   retries capability value of the HBA driver.
 188                                   See scsi_ifsetcap(9F) for details.
 189 
 190 
 191        qfull-retry-interval
 192                                   The supplied value is passed as the qfull-
 193                                   retry interval capability value of the HBA
 194                                   driver. See scsi_ifsetcap(9F) for details.
 195 
 196 
 197        allow-bus-device-reset
 198                                   The default value is 1, which allows
 199                                   resetting to occur. Set this value to 0
 200                                   (zero) to prevent the sd driver from calling
 201                                   scsi_reset(9F) with a second argument of
 202                                   RESET_TARGET when in error-recovery mode.
 203                                   This scsi_reset(9F) call may prompt the HBA
 204                                   driver to send a SCSI Bus Device Reset
 205                                   message. The scsi_reset(9F) call with a
 206                                   second argument of RESET_TARGET may result
 207                                   from an explicit request via the USCSICMD
 208                                   ioctl. Some high-availability multi-
 209                                   initiator systems may wish to prohibit the
 210                                   Bus Device Reset message; to do this, set
 211                                   the allow-bus-device-reset property to 0.
 212 
 213 
 214        optical-device-bind
 215                                   Controls the binding of the driver to non
 216                                   self-identifying SCSI target optical
 217                                   devices. (See scsi(4)). The default value is
 218                                   1, which causes sd to bind to DTYPE_OPTICAL
 219                                   devices (as noted in scsi(4)).  Setting this
 220                                   value to 0 prevents automatic binding. The
 221                                   default behavior for the SPARC-based sd
 222                                   driver prior to Solaris 9 was not to bind to
 223                                   optical devices.
 224 
 225 
 226        power-condition
 227                                   Boolean type, when set to False, it
 228                                   indicates that the disk does not support
 229                                   power condition field in the START STOP UNIT
 230                                   command.
 231 
 232 
 233 
 234        In addition to the above properties, some device-specific tunables can
 235        be configured in sd.conf using the sd-config-list global property. The
 236        value of this property is a list of duplets. The formal syntax is:
 237 
 238          sd-config-list = <duplet> [, <duplet> ]* ;
 239 
 240          where
 241 
 242          <duplet>:= "<vid+pid>"     , "<tunable-list>"
 243 
 244          and
 245 
 246          <tunable-list>:= <tunable>  [,     <tunable> ]*;
 247          <tunable> = <name> : <value>
 248 
 249          The <vid+pid> is the string that is returned by the target device
 250          on a SCSI inquiry command.
 251 
 252          The <tunable-list> contains one or more tunables to apply to
 253          all target devices with the specified <vid+pid>.
 254 
 255          Each <tunable>   is a <name> : <value> pair. Supported
 256          tunable names are:
 257 
 258             delay-busy: when busy, nsecs of delay before retry.
 259 
 260             retries-timeout: retries to perform on an IO timeout.
 261 
 262 
 263        mmc-gesn-polling
 264                            For optical drives compliant with MMC-3 and
 265                            supporting the GET EVENT STATUS NOTIFICATION
 266                            command, this command is used for periodic media
 267                            state polling, usually initiated by the DKIOCSTATE
 268                            dkio(7I) ioctl. To disable the use of this command,
 269                            set this boolean property to false. In that case,
 270                            either the TEST UNIT READY or zero-length WRITE(10)
 271                            command is used instead.
 272
