NAME         top

       hpsa - HP Smart Array SCSI driver

SYNOPSIS         top

       modprobe hpsa [ hpsa_allow_any=1 ]

DESCRIPTION         top

       hpsa is a SCSI driver for HP Smart Array RAID controllers.

       hpsa_allow_any=1: This option allows the driver to attempt to
       operate on any HP Smart Array hardware RAID controller, even if
       it is not explicitly known to the driver.  This allows newer
       hardware to work with older drivers.  Typically this is used to
       allow installation of operating systems from media that predates
       the RAID controller, though it may also be used to enable hpsa to
       drive older controllers that would normally be handled by the
       cciss(4) driver.  These older boards have not been tested and are
       not supported with hpsa, and cciss(4) should still be used for

   Supported hardware
       The hpsa driver supports the following Smart Array boards:

           Smart Array P700M
           Smart Array P212
           Smart Array P410
           Smart Array P410i
           Smart Array P411
           Smart Array P812
           Smart Array P712m
           Smart Array P711m

           Smart Array E200
           Smart Array E200i
           Smart Array E200i
           Smart Array E200i
           Smart Array E200i
           Smart Array E500
           Smart Array P400
           Smart Array P400i
           Smart Array P600
           Smart Array P700m
           Smart Array P800

   Configuration details
       To configure HP Smart Array controllers, use the HP Array
       Configuration Utility (either hpacuxe(8) or hpacucli(8)) or the
       Offline ROM-based Configuration Utility (ORCA) run from the Smart
       Array's option ROM at boot time.

FILES         top

   Device nodes
       Logical drives are accessed via the SCSI disk driver (sd(4)),
       tape drives via the SCSI tape driver (st(4)), and the RAID
       controller via the SCSI generic driver (sg(4)), with device nodes
       named /dev/sd*, /dev/st*, and /dev/sg*, respectively.

   HPSA-specific host attribute files in /sys
              This is a write-only attribute.  Writing to this attribute
              will cause the driver to scan for new, changed, or removed
              devices (e.g., hot-plugged tape drives, or newly
              configured or deleted logical drives, etc.)  and notify
              the SCSI midlayer of any changes detected.  Normally a
              rescan is triggered automatically by HP's Array
              Configuration Utility (either the GUI or the command-line
              variety); thus, for logical drive changes, the user should
              not normally have to use this attribute.  This attribute
              may be useful when hot plugging devices like tape drives,
              or entire storage boxes containing preconfigured logical

              This attribute contains the firmware version of the Smart

              For example:

                  # cd /sys/class/scsi_host/host4
                  # cat firmware_revision

   HPSA-specific disk attribute files in /sys
              This attribute contains a 32 hex-digit unique ID for each
              logical drive.

              For example:

                  # cd /sys/class/scsi_disk/4:0:0:0/device
                  # cat unique_id

              This attribute contains the RAID level of each logical

              For example:

                  # cd /sys/class/scsi_disk/4:0:0:0/device
                  # cat raid_level
                  RAID 0

              This attribute contains the 16 hex-digit (8 byte) LUN ID
              by which a logical drive or physical device can be
              addressed.  c:b:t:l are the controller, bus, target, and
              lun of the device.

       For example:

                  # cd /sys/class/scsi_disk/4:0:0:0/device
                  # cat lunid

   Supported ioctl() operations
       For compatibility with applications written for the cciss(4)
       driver, many, but not all of the ioctls supported by the cciss(4)
       driver are also supported by the hpsa driver.  The data
       structures used by these ioctls are described in the Linux kernel
       source file include/linux/cciss_ioctl.h.

              These three ioctls all do exactly the same thing, which is
              to cause the driver to rescan for new devices.  This does
              exactly the same thing as writing to the hpsa-specific
              host "rescan" attribute.

              Returns PCI domain, bus, device, and function and "board
              ID" (PCI subsystem ID).

              Returns driver version in three bytes encoded as:

                  (major_version << 16) | (minor_version << 8) |

              Allows "BMIC" and "CISS" commands to be passed through to
              the Smart Array.  These are used extensively by the HP
              Array Configuration Utility, SNMP storage agents, and so
              on.  See cciss_vol_status at ⟨http://cciss.sf.net⟩ for
              some examples.
