NAME
hpsa - HP Smart Array SCSI driver
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 ex‐
plicitly known to the driver. This allows newer hardware to work with
older drivers. Typically this is used to allow installation of operat‐
ing systems from media that predates the RAID controller, though it may
also be used to enable hpsa to drive older controllers that would nor‐
mally 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
Since Linux 4.14, the following Smart Array boards are also supported:
Smart Array 5300
Smart Array 5312
Smart Array 532
Smart Array 5i
Smart Array 6400
Smart Array 6400 EM
Smart Array 641
Smart Array 642
Smart Array 6i
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
Device nodes
Logical drives are accessed via the SCSI disk driver (sd(4)), tape dri‐
ves 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
should not normally have to use this attribute. This attribute
may be useful when hot plugging devices like tape drives, or en‐
tire storage boxes containing preconfigured logical drives.
/sys/class/scsi_host/host*/firmware_revision
This attribute contains the firmware version of the Smart Array.
For example:
# cd /sys/class/scsi_host/host4
# cat firmware_revision
7.14
HPSA-specific disk attribute files in /sys
/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 in‐
clude/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" at‐
tribute.
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)
CCISS_PASSTHRU, CCISS_BIG_PASSTHRU
Allows "BMIC" and "CISS" commands to be passed through to the
Smart Array. These are used extensively by the HP Array Config‐
uration Utility, SNMP storage agents, and so on. See
cciss_vol_status at ⟨http://cciss.sf.net⟩ for some examples.
