If you’re using identical physical disks you won’t notice any “difference” as smartmontools is focused on monitoring physical disks and not controllers or logical disks you can and will not find any information of those in smartmontools. The driver then notifies the SCSI midlayer of these changes. 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. That is, there are some kernels which have overlapping sets of controllers supported by both hpsa and cciss. The binary RPMs created by the source RPMs here do not do these things, they only build the driver module and initrd image.

Install the hpssacli tool:. The cciss driver previously contained a feature which would enable it by default to run on Smart Array controllers which it did not explicitly recognize except so far as to be able to determine that they were some sort of Smart Array.
So far, I haven’t had any luck duplicating this problem. Debian package only builds binary cciss module. OS distros with warnings.

Here’s the man page. Without this fix the system will panic on reboot when the HP cciss rpm has been uninstalled.
One long-haired git at your service Fixed sysfs link issue. Added a procfs interface so users can tell the driver to rescan our devices. But running cciss,1 on sdb gives different results from cciss,0 on sdb. This is on Ubuntu Linux Some models of Smart Array are not able to honor this parameter.

cciss(4): HP Smart Array block driver – Linux man page
Rory 14k 53 A pretty good alternative is cpqarrayd which you can find here: It neither modifies bootloader grub or lilo. Initially, there was some overlap in the boards which these two drivers support.
The hpsa driver is a SCSI driver, while the cciss driver is a block driver. Arrayprobe which may need modifications to work with the hpsa driver. This occurs for all drive pairs. 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.
Last updated Tue Oct 16, latest version is 2. BTW, if you happen across a 2.

To enable this feature of hpsa, the module parameter hpsa. You can use these if you have a supported distribution running a supported kernel. Post as a guest Name. The normal protocol is a four-step process: I have 6 SSD disks.
I have a ML G2 with a array controller. It reports any status changes, like failing disks, to the syslog and optionally to a remote host using SNMP traps. Running cciss,0 on sdbsdcsdd or sde gives the same results.
