Description Gary Smith 2011-02-09 05:58:25 EST
Description of problem:

A new "-o diag" option is on target to be added to the RHEL6.1 fence_ipmilan which sends the IPMI "diag" message to a system in order to trigger system dumps for diagnostic purposes.

Currently stonith action only allows "reboot" and "poweroff". The action is set globally based the stonith-action cluster property but it would be very useful to set this per device to assist with fault analysis.


Actual results:
With fence_ipmilan executed manually with "-o diag" it works fine.


Additional info:

In pacemaker, set action="diag" instead of action="reboot" :

primitive restofencenode1 stonith:*fence_ipmilan* \
   params ipaddr="<my ipaddr>" login="<mylogin>" passwd="<mypasswd>"
pcmk_host_check="static-list" pcmk_host_list="node1" *action="diag"* \
