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?
With best Regards,
Tobias

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.
2. File a BZ with an RFE to add your fencing agent.
The latter should be done regardless of the first.

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.
