Fence agent with support for HMC v3
You have to enter '-H 3' to set HMC version.
fence_lpar -a hmc-tucks -x -s pseries -n ibm-p4-01 -l <snip> -p <snip> -o
status
Failed: You have to enter valid version number: 3 or 4
Please use '-h' for usage
fence_lpar -h
<snip>
-H, --hmc-version=<version> Force HMC version to use: 3, 4 (default)
</snip>
A bug? It should work without specifying hmc version. Other way it could break
lots of existing setups.
I also changed sys.path.append("@FENCEAGENTSLIBDIR@") to
sys.path.append("/usr/share/fence") for it to work.

Patched fence library
Grr, -H should be optional but python distincts between 4 and "4" :(
It should not broke anything as only v4+ was supported before.
Changing of path is acceptable as I put there a devel code not a deployment where such things are handled but I should warn you :)
Any ideas?
I looks like it can't get the power status correctly...
$ ./fence_lpar.py -a hmc-tucks.englab.brq.redhat.com -l <snip> -p <snip> -H 3 -x -s pseries -n ibm-ps-01 -o off

You have to enter existing name of machine (-n). Error message should be more clear - I will open a new bugzilla for it as this can be problem for several agents. Thanks Marek, Works great. You should probably do error handlers for this, and other type of messages... An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2009-1050.html |
