(See > http://man7.org/linux/man-pages/licenses.html) Hi Steve, So, in the end, I didn't put this page out with the recent man-pages-3.33 release, since I hadn't finished processing it. Thank you also for this page. As with the ccis(4) page, the fundamental content is great. I did some editing as follows: 1. I removed the AUTHORS section, since that's not used in man-pages. 2. I did some formatting fixes (to be consistent with man-pages conventions) and some copyediting, rewording some long sentences, etc. Hopefully, I did not change the meaning anywhere, but you should carefully read the entire page to check. Because of 2, could I ask you to please take a look at the revised page, and send me back any fixes that are required (or an ACK if none are required).

This allows newer hardware to work with older drivers. Typically this is used to allow installation of operating systems from media which predates the RAID controller, though it may also be used to enable .B hpsa to drive older controllers that would normally be handled by the .BR cciss (4) driver. These older boards have not been tested and are not supported with .BR hpsa , and .BR cciss (4) should still be used for these. .SS Supported Hardware The .B hpsa driver supports the following Smart Array boards: .nf 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 .fi .SS Configuration Details To configure HP Smart Array controllers, use the HP Array Configuration Utility (either .BR hpacuxe (8) or .BR hpacucli (8)) or the Offline ROM-based Configuration Utility (ORCA) run from the Smart Array's option ROM at boot time. .SH FILES .SS Device Nodes Logical drives are accessed via the SCSI disk driver .RB ( sd (4)), tape drives via the SCSI tape driver .RB ( st (4)), and the RAID controller via the SCSI generic driver .RB ( sg (4)), with device nodes named .IR /dev/sd*, .IR /dev/st* , and .IR /dev/sg* , respectively. .SS HPSA-Specific Host Attribute Files in /sys .TP .I /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 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 pre-configured logical drives. .TP .I /sys/class/scsi_host/host*/firmware_revision This attribute contains the firmware version of the Smart Array. For example: .nf # \fBcd /sys/class/scsi_host/host4\fP # \fBcat firmware_revision\fP 7.14 .fi .SS HPSA-Specific Disk Attribute Files in /sys .TP .I /sys/class/scsi_disk/c:b:t:l/device/unique_id This attribute contains a 32 hex-digit unique ID for each logical drive .nf For example: # \fBcd /sys/class/scsi_disk/4:0:0:0/device\fP # \fBcat unique_id\fP 600508B1001044395355323037570F77 .fi .TP .I /sys/class/scsi_disk/c:b:t:l/device/raid_level This attribute contains the RAID level of each logical drive. .nf For example: # \fBcd /sys/class/scsi_disk/4:0:0:0/device\fP # \fBcat raid_level\fP RAID 0 .fi .TP .I /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. .IR c : b : t : l are the controller, bus, target and lun of the device. .nf For example: # \fBcd /sys/class/scsi_disk/4:0:0:0/device\fP # \fBcat lunid\fP 0x0000004000000000 .fi .SS Supported ioctl() operations For compatibility with applications written for the .BR cciss (4) driver, many, but not all of the ioctls supported by the .BR cciss (4) driver are also supported by the .B hpsa driver. The data structures used by these ioctls are described in the kernel source file .IR include/linux/cciss_ioctl.h . .TP .BR 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. .TP .B CCISS_GETPCIINFO Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID). .TP .B CCISS_GETDRIVVER Returns driver version in three bytes encoded as: .sp (major_version << 16) | (minor_version << 8) | (subminor_version) .TP .BR 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 Configuration Utility, SNMP storage agents, etc. See .I cciss_vol_status at .I http://cciss.sf.net for some examples. .SH "SEE ALSO" .BR cciss (4), .BR sd (4), .BR st (4), .BR cciss_vol_status (8), .BR hpacucli (8), .BR hpacuxe (8), .IR http://cciss.sf.net , and the Linux kernel source files .I Documentation/scsi/hpsa.txt and .I Documentation/ABI/testing/sysfs-bus-pci-devices-cciss .\" .SH AUTHORS .\" Don Brace, Steve Cameron, Tom Lawler, Mike Miller, Scott Teel .\" and probably some other people.
