cciss - HP Smart Array block driverSYNOPSIS
DESCRIPTION
Note:This obsolete driver was removed from the kernel in version 4.14,as it is superseded by thehpsa(4)driver in newer kernels.ccissis a block driver for older HP Smart Array RAID controllers.
Options
cciss_allow_hpsa=1:This option prevents theccissdriver from attempting to drive any controllers that thehpsa(4)driver is capable of controlling, which is to say, theccissdriver is restricted by this option to the following controllers:Supported hardware
Theccissdriver supports the following Smart Array boards:Configuration details
To configure HP Smart Array controllers,use the HP Array Configuration Utility(eitherhpacuxe(8)orhpacucli(8))or the Offline ROM-based Configuration Utility (ORCA)run from the Smart Array's option ROM at boot time.FILES
Device nodes
The device naming scheme is as follows:Files in /proc
The files/proc/driver/cciss/cciss[0-9]+contain information aboutthe configuration of each controller.For example:$ cd /proc/driver/cciss$ ls -ltotal 0-rw-r--r-- 1 root root 0 2010-09-10 10:38 cciss0-rw-r--r-- 1 root root 0 2010-09-10 10:38 cciss1-rw-r--r-- 1 root root 0 2010-09-10 10:38 cciss2$ cat cciss2cciss2: HP Smart Array P800 ControllerBoard ID: 0x3223103cFirmware Version: 7.14IRQ: 16Logical drives: 1Current Q depth: 0Current # commands on controller: 0Max Q depth since init: 1Max # commands on controller since init: 2Max SG entries since init: 32Sequential access devices: 0

SCSI tape drive and medium changer support
SCSI sequential access devices and medium changer devices are supported andappropriate device nodes are automatically created (e.g.,Hp Smart Array P410 Driver
/dev/st0,/dev/st1,etc.; seest(4)for more details.)You must enable 'SCSI tape drive support for Smart Array 5xxx' and'SCSI support' in your kernel configuration to be able to use SCSItape drives with your Smart Array 5xxx controller.Additionally, note that the driver will not engage the SCSI core atinit time.The driver must be directed to dynamically engage the SCSI core via the/procfilesystem entry,which the 'block' side of the driver creates as/proc/driver/cciss/cciss*at run time.This is because at driver init time,the SCSI core may not yet be initialized (because the driver is a blockdriver) and attempting to register it with the SCSI core in such a casewould cause a hang.This is best done via an initialization script(typically in/etc/init.d,but could vary depending on distribution).For example:
for x in /proc/driver/cciss/cciss[0-9]*do
echo 'engage scsi' > $xdone
Once the SCSI core is engaged by the driver, it cannot be disengaged(except by unloading the driver, if it happens to be linked as a module.)
Note also that if no sequential access devices or medium changers aredetected, the SCSI core will not be engaged by the action of the abovescript.
Hot plug support for SCSI tape drives
Hot plugging of SCSI tape drives is supported, with some caveats.Theccissdriver must be informed that changes to the SCSI bushave been made.This may be done via the/procfilesystem.For example:
echo 'rescan' > /proc/scsi/cciss0/1
This causes the driver to:
Hp Smart Array P400 Controller Driver Server 2016
- 1.
- query the adapter about changes to thephysical SCSI buses and/or fibre channel arbitrated loop, and
- 2.
- make note of any new or removed sequential access devicesor medium changers.
The driver will output messages indicating whichdevices have been added or removed and the controller, bus, target, andlun used to address each device.The driver then notifies the SCSI midlayerof these changes.
Note that the naming convention of the/procfilesystem entriescontains a number in addition to the driver name(e.g., 'cciss0'instead of just 'cciss', which you might expect).
Note:Onlysequential access devices and medium changers are presentedas SCSI devices to the SCSI midlayer by theccissdriver.Specifically, physical SCSI disk drives arenotpresented to the SCSI midlayer.The only disk devices that are presented to the kernel are logicaldrives that the array controller constructs from regions onthe physical drives.The logical drives are presented to the block layer(not to the SCSI midlayer).It is important for the driver to prevent the kernel from accessing thephysical drives directly, since these drives are used by the arraycontroller to construct the logical drives.
SCSI error handling for tape drives and medium changers
Hp Smart Array P400 Driver Windows 7
The Linux SCSI midlayer provides an error-handling protocol thatis initiated whenever a SCSI command fails to complete within acertain amount of time (which can vary depending on the command).Theccissdriver participates in this protocol to some extent.The normal protocol is a four-step process:Theccissdriver is a blockdriver as well as a SCSI driver and only the tape drives and mediumchangers are presented to the SCSI midlayer.Furthermore, unlike morestraightforward SCSI drivers, disk I/O continues through the blockside during the SCSI error-recovery process.Therefore, theccissdriver implements only the first two of these actions,aborting the command, and resetting the device.Note also that most tape drives will not obligein aborting commands, and sometimes it appears they will not evenobey a reset command, though in most circumstances they will.If the command cannot be aborted and the device cannot bereset, the device will be set offline.
In the event that the error-handling code is triggered and a tape drive issuccessfully reset or the tardy command is successfully aborted, thetape drive may still not allow I/O to continue until some commandis issued that positions the tape to a known position.Typically you must rewind the tape (by issuingmt -f /dev/st0 rewindfor example) before I/O can proceed again to a tape drive that was reset.
