Is the module in some other package which needs to be installed? A new Smart Array driver called “hpsa” has been accepted into the main line linux kernel as of Dec 18, , in linux See the “st” man page for more details. It can no longer find the rhel5 base media cciss driver following an uninstalled of an HP cciss rpm. The only disk devices that are presented to the kernel are logical drives that the array controller constructs from regions on the physical drives. The monitor threads allow the driver to detect such.

One would have expected a more professional approach from the kernel team than just “meh, it probably works”. This is because at driver init time, the SCSI core may not yet be initialized because the driver is a block driver and attempting to register it with the SCSI core in such a case would cause a hang.

Everything is fine up until the when the root filesystem should be mounted. Hpsa should be fine for new installs on these controllers, however.

The earlier fix would be called anytime something changed.

This leads me to think that someone has been tinkering and clobbering when preparing the ccisz update for OpenSUSE? For multipath configurations acheived via kerneel higher level driver, such. The system root partition did not appear, and eventually i ended up in the emergency shell. The hpsa driver is a SCSI driver, while the cciss driver is a block driver. Added dynamic outstanding command turning on a per controller basis. There may be other software designed to work with cciss e.

This should not affect.

Or someone that wants to entirely avoid the booting problem when updating their Linux kernel. There are no changes in the cciss modified driver that can affect performance.

Once you have this, you need to create device nodes in. If a failure occurs. May 6th, 5. Then the system can be booted to the previous kernel version by selecting it in the GRUB2 boot menu.


On a server I have running Some models of Smart Array are not able to honor this parameter.
