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"* \
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: When using the fence_ipmilan fencing agent, Pacemaker now accepts "diag" as a valid per-device stonith action. With this action enabled, a fenced node receives the "DIAG" signal and creates a dump for diagnostic purposes.
