Hi,

afaik it should work when this fencing agent gets added to the engine as was done to drac7 from dell recently here:

https://bugzilla.redhat.com/show_bug.cgi?id=1046625

http://gerrit.ovirt.org/#/c/22833/

It seems to boil down to an sql command:

"select fn_db_add_config_value('FenceAgentMapping','drac7=ipmilan,ilo2=ilo,ilo3=ipmilan,ilo4=ipmilan' ,'general');"

I don't know if intelmodular has an ipmi compatible mode?

So I think you have 2 options:

1. You may hack the DB yourself.

Hi Here are detailed instructions how to add a custom agent: a) Add your new agent to VdsFenceType option_value in vdc_options table for the relevant cluster version b) Add agent options mappings to VdsFenceOptionMapping option_value in vdc_options table for the relevant cluster version c) If the agent maps actually to another agent , add that to FenceAgentMapping option_value in vdc_options Example : Adding zzz agent support for version 3.3 that maps internally to ipmi and have just port setting (from: port, slot, secure) that maps to the fencing script ipport a) VdsFenceType for 3.3 becomes "apc,apc_snmp,bladecenter,cisco_ucs,drac5,eps,ilo,ilo2,ilo3,ilo4,ipmilan,rsa,rsb,wti,zzz" b) VdsFenceOptionMapping for 3.3 becomes "apc:secure=secure,port=ipport,slot=port;apc_snmp:port=port;bladecenter:secure=secure,port=ipport,slot=port;cisco_ucs:secure=ssl,slot=port;drac5:secure=se cure,slot=port;eps:slot=port;ilo:secure=ssl,port=ipport;ipmilan:;ilo2:secure=ssl,port=ipport;ilo3:;ilo4:;rsa:secure=secure,port=ipport;rsb:;wti:secure=secure,port=ipport,slot=port;zzz:port=ipport" c) FenceAgentMapping becomes "ilo2=ilo,ilo3=ipmilan,ilo4=ipmilan,zzz=ipmilan" NOTES 1) Please backup your database 2) You should restart the engine for this to take place 3) Custom definitions will be overridden in your next upgrade , for the long run please fill RFE so it will be part of the supported agents Please let me know if that works for you.

2. File a BZ with an RFE to add your fencing agent.

The latter should be done regardless of the first.

Heho, we are using an intel modular server (IMS) as virtualization center in our university chair.

These systems should now be migrated to ovirt. However, apparently fencing/power management via /usr/sbin/fence_intelmodular can not be configured in ovirt 3.3.

Does anyone have an idea how to solve this issue? Is there maybe a simple way to add custom fence agents?
