It is not necessary to develop a fencing agent for SUN. Just use the ipmi
agent, it works, as SUN supports IPMI 2.0 on the X4x00.
How to do it:
Create a user for fencing through the SUN Remote Service Board Web Management,
give this user full rights.
Install if not already done: OpenIPMI and OpenIPMI-tools
Test the fencing with the following command:
fence_ipmilan -l username -p password -a IPAddresse-management -o status -v
This should give you back something like:
Getting status of IPMI:192.168.160.12...Spawning: '/usr/bin/ipmitool -I lan -H
IPaddress -U username -P password -v chassis power status'...
Chassis power = On
Done
For SUN Fire V40Z servers fencing will also work with IPMI, but it is a little
bit different, as it only support IPMI 1.5:
Log in through ssh to the Remote Service board, enable ipmi:
ipmi enable channel lan
(uhh, you should give ipmi a password, but don't ask how, look into the
documentation)
The fencing command looks like the following:
fence_ipmilan -p password -a IPAddresse-management -o status -v
Note that there is no Username!
Sincerly,
Klaus
