    hpsa

    
    
    

    SYNOPSIS

           modprobe hpsa [ hpsa_allow_any=1 ]
    
    
    

    DESCRIPTION

           hpsa is a SCSI driver for HP Smart Array RAID controllers.
    
       Options
           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 these.
    
       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
               StorageWorks P1210m
    
       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

       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
           /sys/class/scsi_host/host*/rescan
                  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  com-
                  mand-line  variety);  thus,  for logical drive changes, the user
    
           /sys/class/scsi_disk/c:b:t:l/device/unique_id
                  This  attribute contains a 32 hex-digit unique ID for each logi-
                  cal drive.
    
                  For example:
    
                      # cd /sys/class/scsi_disk/4:0:0:0/device
                      # cat unique_id
                      600508B1001044395355323037570F77
    
           /sys/class/scsi_disk/c:b:t:l/device/raid_level
                  This attribute contains the RAID level of each logical drive.
    
                  For example:
    
                      # cd /sys/class/scsi_disk/4:0:0:0/device
                      # cat raid_level
                      RAID 0
    
           /sys/class/scsi_disk/c:b:t:l/device/lunid
                  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
                      0x0000004000000000
    
       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.
    
           CCISS_DEREGDISK, CCISS_REGNEWDISK, CCISS_REGNEWD
                  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.
    
           CCISS_GETPCIINFO
                  Returns PCI domain, bus, device and function and "board ID" (PCI
                  subsystem ID).
    
           CCISS_GETDRIVVER
                  Returns driver version in three bytes encoded as:
    
                      (major_version << 16) | (minor_version << 8) |
                          (subminor_version)
