HP CCISS LINUX DRIVER
But only the cciss,X in that matters, not the sdY. Added dynamic outstanding command turning on a per controller basis. From time to time there may be instances in which hardware or driver features are not supported by the cciss driver which comes with your distribution or kernel, because it is too old, or the hardware is too new, etc. You may try to use these to build a binary RPM.

The function prints a message then retries the command that returned with a unit attention.
You may try to use these to build a binary RPM. Last updated Tue Oct 16, latest version is 2. This new driver will support new Smart Array products linkx forward, and the cciss driver will eventually be deprecated. The current list of controllers that are supported by cciss only: All forum topics Previous Topic Next Topic.
BTW, if you happen across a 2. This patch will get called only once for each controller. Fixed wrong usage of a pointer for sysfs symlink.

SCSI error handling for tape drives and medium changers The Linux SCSI midlayer provides an error-handling protocol that is initiated whenever a SCSI command fails to complete within a certain amount of time which can vary depending on the command. Note also that if no sequential access devices or medium changers are detected, the SCSI core will not be engaged by the action of the above script.
Later, after checking this one out a bit more, I’ll edit this to reflect what I ccise. Sign up or log in Sign up using Google.
The following list of controllers are supported by cciss on distributions based on kernels before 2. Note also that most tape drives will not oblige in aborting commands, and sometimes it appears they will ccisw even obey a reset command, though in most circumstances they will.
A new Smart Array driver called “hpsa” has been accepted into the main line linux kernel as of Dec 18,in linux The normal protocol is a four-step process: The only disk devices that are presented to the kernel are logical drives that the array controller constructs from regions on the physical drives.

Cleaned up code for lihux and removing logical volumes. With all the various distributions, it is difficult to come up with a set of bulletproof universal instructions for making such a switch, so we recommend that you simply continue to use cciss in such instances.
From time to time there may be instances in which hardware or driver features are not supported by the cciss driver which comes with your distribution or kernel, because it is too old, or the hardware is too new, etc. The hpsa driver is a Ccsis driver, while the cciss driver is a block driver.
This binary RPM may then be installed in the usual way, for instance: This option cciiss the cciss driver from attempting to drive any controllers that the hpsa 4 driver is capable of controlling, which is to say, the cciss driver is restricted by this option to the following controllers: You can think of this as a daemonized version of arrayprobe, in that both of them detect failures in the same way by looking cdiss “events” reported by the controller, cpqarrayd in real time, arrayprobe after the fact.
This feature has been removed, as any Smart Arrays not known to cciss are now presumed to be claimed by the hpsa driver.

If you’ve been using cciss already on these controllers, it is not recommended that you attempt to upgrade your running system to switch from cciss to hpsa unless you have a very good reason to do so and know what you are doing. The driver will output messages indicating which devices have been added or removed and the controller, bus, target and lun used to address each device.
