NAME
     cpqary3 - provides disk and SCSI tape support for  HP  Smart
     Array controllers

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 Configured address and what types of  dev-
     ices are attached to it.

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


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


     The target driver's configuration file need entries if  sup-
     port  is  needed  for  targets  numbering  greater  than the
     default number of targets  supported  by  the  corresponding
     target driver.


     By default, entries for SCSI target  numbers  0  to  15  are
     present  in sd.conf. Entries for target numbers 16 and above
     are added in SCSI class in the sd.conf file  for  supporting
     corresponding logical volumes.


     If SCSI tape drives are connected to the supported controll-
     ers, entries for target IDs from 33 to 33+n must be added in
     the /kernel/drv/st.conf file under scsi class,  where  n  is
     the  total  number  of  SCSI  tape  drives  connected to the

     controller with largest number of tape drives  connected  to
     it,  in  the  existing  configuration. For example, two sup-
     ported controllers, c1 and c2 are present in the system.  If
     controller c1 has two tape drives and controller c2 has five
     tape drives connected, entries for target IDs 33 through  38
     are  required  under scsi class in /kernel/drv/st.conf file.
     The maximum number of tape drives that can be connected to a
     controller  is  28.  With  1.90  and  later  versions of the
     cpqary3 driver, if tape drives are connected  to  the  Smart
     Array  SAS  controllers,  target  ID entries for tape drives
     from 65 to 65+n must be  added  in  the  /kernel/drv/st.conf
     file under the scsi class.

     cpqary3 Release Notes

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