NAME
       cpqary3	-  provides disk and SCSI tape support for HP Smart Array con‐
       trollers

DESCRIPTION
       The cpqary3 module provides low-level interface	routines  between  the
       common  disk  I/O  subsystem  and  the  HP SMART Array controllers. The
       cpqary3 driver provides disk and SCSI tape support  for	the  HP	 Smart
       Array controllers.

       Please  refer  to the cpqary3 Release Notes, for the supported HP Smart
       Array Controllers and Storage boxes.

       Each of the controller should be the sole initiator on a SCSI bus. Auto
       configuration  code determines if the adapter is present at the Config‐
       ured address and what types of devices are attached to it.

   Configuration
       Use the Array Configuration Utility to configure the controllers.  Each
       controller can support up to 32 logical volumes. In addition, each con‐
       troller supports up to a maximum of 28 connected SCSI tape drives. With
       1.90  and  later	 versions  of  cpqary3 driver, HP Smart Array SAS con‐
       trollers, having Firmware Revision 5.10 or later,  support  64  logical
       drives.	This  firmware	also supports Dual Domian Multipath configura‐
       tions.

       The driver attempts to initialize itself in accordance with the	infor‐
       mation found in the configuration file, /kernel/drv/cpqary3.conf.

   Driver Properties
       The following properties can be specified in /kernel/drv/cpqary3.conf:

       cpqary3-hbcheck-interval=seconds;

	   The time in seconds between checks of the controller heartbeat. The
	   default is 180 seconds. A value of 0 disables the heartbeat	check.
	   When	 a  controller	fault recovery method other than none is used,
	   reducing the heart beat check interval can reduce the time that  it
	   takes  for  the  driver  to detect a controller fault. The smallest
	   recommended interval is 5 seconds.

       cpqary3-hba-fault-recovery=method;

	   The controller fault recovery method to use. When the controller or
	   firmware  becomes unresponsive, the driver attempts to recover. The
	   following recovery methods are available:

	   none		 The driver does not attempt  recovery.	 This  is  the
			 default.

			 I/O requests pending at the controller at the time of
			 the fault does not complete.  Applications  or	 other
			 parts	of the system that are waiting on this I/O can
			 become unresponsive. Future I/O requests  fail.  This
			 is the historical behavior of the driver. A reboot is
			 required to recover user of  the  failed  controller.
			 This  method  must be used for controllers with RAID5
			 or above logical volumes.

	   quarantine	 The driver attempts to quarantine the controller.  If
			 quarantine  is	 successful,  pending I/O requests are
			 timed out. Applications or other parts of the	system
			 receive  I/O  errors. Future I/O requests to the con‐
			 troller continues to fail. Redundant controllers  can
			 be  used  with software RAID, such as ZFS, to provide
			 fault tolerance. A reboot is required to recover full
			 use of the failed controller.

			 Do  not  use this method with	controllers with RAID5
			 or above logical volumes. When using  quarantine,  HP
			 recommends  the  use  of a filesystem that can verify
			 data integrity, such as ZFS. This method is only sup‐
			 ported	 for P410 and P410i controllers,  and requires
			 firmware version 5.00 or higher.

       cpqary3 Release Notes

NOTES
       The  Smart  Array  controllers  supported by the current version of the
       cpqary3 driver do not support  format  unit  SCSI  command.  Therefore,
       selecting  the  format option under the format utility main menu is not
       supported. In addition, the repair option  under	 format	 utility  main
       menu  is	 not  supported as this operation is not applicable to Logical
       volumes connected to the supported Smart Array controllers.

       The names of the block files can be found in /dev/dsk. The names of the
       raw files can be found in /dev/rdsk.
