This allows newer hardware to work with older drivers. ProLiant Management Component Pack. 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. Worked fine, no firmware required. Removed unneeded lock in sysfs code. 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.

Installation report in Installation report in Daily Builds Daily builds are available from the d-i devel page. On booting I found the message “modprobe: If there is anything else I can do to clarify, I am more than happy to accommodate. See post 3 in this thread at linuxquestions which is a rough howto for CentOS.
HP/ProLiant – Debian Wiki
See full activity log. I also tried using 16MB of read ahead cache, but it didn’t really yield significant gains, so I decided that 8MB was enough.
Use ‘simple mode’ rather than ‘performant mode’ int top output when hanging top – Changed in linux Ubuntu: The hpsa driver is a SCSI driver, while the cciss driver is a block driver. If you would like to run hpsa instead, there is a new module parameter to cciss, “cciss. Tablets Laptops and Netbooks Phones.
The earlier fix would be called anytime something changed. Ho issue where ACU would hang after several operations. llnux
HP ProLiant Servers
Yesterday by doing tests on different processes, I disabled postfix and the server stopped hanging. To get it working for me, I installed the kernel from experimental 2.
Logs to syslog, and optionally, sends SNMP traps. 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.
Ubuntu Manpage: hpsa – HP Smart Array SCSI driver
In the kernel documentation linux-source Allow hpsa driver to access unknown HP Smart Array hardware int parm: Fixed bug where deleting logical volumes could hang the system.
Information on official HP support offerings for Debian can be found on http: More details are available in this HP-provided document. This change has been made by an automated script, maintained by the Ubuntu Kernel Team. If you’re already running cciss on these devices, and upgrade to a kernel containing the hpsa driver, you shouldn’t have to do anything, as cciss will continue to claim these devices.
Tuning a HP Smart Array P400 with Linux – why tuning really matters…
Disabled Wait for Cache Room: Create a directory and unpack the tarball. Fix firmware version not being printed in procfs.
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 yp determine that they were some sort of Smart Array. Fixed “out of memory” error introduced in the 2. Since weeks now, my main server is hanging for no apparent reasons.
In the case of kernels with cciss and hpsa drivers which do have overlapping sets of supported controllers, by default, cciss will claim these devices if it is loaded prior to hpsa which it normally will be. Cleaned up code for adding and removing logical volumes.
Initially, there was some overlap in the boards which these two drivers support.
