I assume I have set up them up incorrectly or am missing a library or dependency. When I log into the OMSA web interface I can't see anything omsa

Also, omreport tells me nothing;

root@box:~# omreport storage controller
No controllers found

I assume these two will use the same source of information so what ever is wrong will fix them both.

I set up OMSA as per these instructions.

Also I have compiled MegaCLI (as this is a PowerEdge 2950 with a Perc 6/i controller) and I have used that to update the RAID firmware, so that works, but the Dell tools aren't.

What have I missed during set up?

root@box:~# cat /etc/issue
Debian GNU/Linux 6.0 \n \l

root@box:~# uname -a
Linux box 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux

This is what I have done under Debian 6 x86_64, Kernel 3.4.9, to get OMSA working although the storage controller isn't showing up. I have MegaCLI working now which is a better in my opinion so I am happy with this;

# Kernel modules
sudo modprobe ipmi_msghandler
sudo modprobe ipmi_devintf
sudo modprobe ipmi_s
# Sometimes this is `sudo modprobe ipmi_si` on 64bit machines

sudo -i
echo "ipmi_msghandler" >> /etc/modules
echo "ipmi_devintf" >> /etc/modules
echo "ipmi_si" >> /etc/modules

# To use a repo stop here and perform add to /etc/apt/sources.list

# then run;
# wget http://ftp.sara.nl/debian_sara.asc
# sudo apt-key add debian_sara.asc
# sudo apt-get update 
# Now there is no need to download the debian packages below

#Install IPMI tools;
sudo apt-get install openipmi

# If not use the deb packages below but the repo above, at this point you can execute;
# sudo apt-get install dellomsa 

#Grab OMSA and debian package (can be http): ONLY IF NOT USING REPO ABOVE

You might try to follow the steps at


to install the latest version. Works for me on recent machines (R620, R720), but I didn't test it on 3.4 kernels yet...

  • I know of this site, but it likely won't work installing the newest OMSA on PE2950, the hardware is too old for the latest OMSA and has compatibility issues (some features don't work). This was more of an exercise in matching the OMSA version to the hardware version, not the OS version (although we can't rule out that the OS version will play some part in it!) – jwbensley Jan 8 '13 at 15:36
