  14 .TH CPQARY3 7D Aug 26, 2013"
  15 .SH NAME
  16 cpqary3 - provides disk and SCSI tape support for HP Smart Array controllers
  17 .SH DESCRIPTION
  18 .LP
  19 The cpqary3 module provides low-level interface routines between the common
  20 disk I/O subsystem and the HP SMART Array controllers. The cpqary3 driver
  21 provides disk and SCSI tape support for the HP Smart Array controllers.
  22 .LP
  23 Please refer to the cpqary3 release notes, for the supported HP Smart Array
  24 Controllers and Storage boxes.
  25 .LP
  26 Each controller should be the sole initiator on a SCSI bus. Auto
  27 configuration code determines if the adapter is present at the Configured
  28 address and what types of devices are attached to it.
  29 .SH CONFIGURATION
  30 Use the Array Configuration Utility to configure the controllers. Each
  31 controller can support up to 32 logical volumes. In addition, each controller
  32 supports up to a maximum of 28 connected SCSI tape drives.
  33 With 1.90 and later versions of cpqary3 driver, HP Smart Array SAS controllers,
  34 having Firmware Revision 5.10 or later, will support 64 logical drives. This
  35 firmware also supports Dual Domian Multipath configurations.
  36 .LP
  37 The driver attempts to initialize itself in accordance with the information
  38 found in the configuration file, /kernel/drv/cpqary3.conf.
  39 .LP
  40 New component - hmaeventd which logs the storage events onto console and to the
  41 Integrated Management Log is made a part of HPQhma 5.0.0 package, which is not
  42 part of the operating system.  Therefore, by default, notify on event
  43 functionality is disabled in the driver from 2.1.0 onwards.  Storage event
  44 logging may be enabled in the driver by modifying cpqary3.conf to set the
  45 cpqary3_noe property to "on".  Modification of driver properties requires
  46 reloading the driver, which in most cases will occur only following a reboot of
  47 the system.
  48 .LP
  49 The target driver's configuration file shall need entries if support is needed
  50 for targets numbering greater than the default number of targets supported by
  51 the corresponding target driver.
  52 .LP
  53 By default, entries for SCSI target numbers 0 to 15 are present in sd.conf.
  54 Entries for target numbers 16 and above must be added to the \&'scsi' class in
  55 sd.conf to support additional corresponding logical volumes.
  56 .LP
  57 If SCSI tape drives are connected to the supported controllers, entries for
  58 target IDs from 33 to 33+N must be added in the /kernel/drv/st.conf file under
  59 \&'scsi' class, where N is the total number of SCSI tape drives connected to the
  60 controller with largest number of tape drives connected to it, in the existing
  61 configuration. For example, two supported controller, c1 and c2 are present in
  62 the system. If controller c1 has two (2) tape drives and controller c2 has five
  63 (5) tape drives connected, then entries for target IDs 33 thru 38 are required
  64 under 'scsi' class in /kernel/drv/st.conf file. The maximum number of tape
  65 drives that can be connected to a controller is 28. With 1.90 and later versions
  66 of cpqary3 driver, if tape drives are connected to Smart Array SAS controllers,
  67 then target ID entries for tape drives from 65 to 65+N must be added in
  68 /kernel/drv/st.conf file under the \&'scsi' class.

  79 .SH NOTES
  80 .LP
  81 The Smart Array controllers supported by the current version of the
  82 cpqary3 driver do not support 'format unit' SCSI command. Hence, selecting
  83 \&'format' option under 'format' utility main menu is not supported. In addition,
  84 the 'repair' option under 'format' utility main menu is not supported as this
  85 operation is not applicable to Logical volumes connected to the supported Smart
  86 Array controllers.
