Shall float a patch that does the following:
1) Bring this new behaviour under the already existing OPENSAF_MANAGE_TIPC
variable, such that the default staging behaviour is not altered. The behaviour
was not put under this flag originally (when this change was made) was to
ensure this goes through testing, as a default behaviour.
i.e.
/* This Variable controls whether FM will trigger failover immediately
* upon recieving down event of critical services or will wait
* for node_downevent. By default, OPENSAF_MANAGE_TIPC = yes,
* If this variable is set to yes, OpenSAF rmmods tipc which means
* NODE_down will happen immediately and there is no need to act on
service down.
* If this variable is set to no, user would have done only do
/etc/init.d/opensafd stop to trigger failover,
* and no rmmod is done, which means no NODE_DOWN event will arrive, and
* therefore FM has to act on service down events of critical service,
* In the short term, FM will use service down events of AMFND, IMMD
and IMMND
* to trigger failover.
*/
2) When this variable is set to false, FM will postpone failover till IMMD and
IMMND downs are recieved. This is for the short term, and will ensure further
testing to uncover all further issues. Most importantly if/when the issue gets
reproduced, MDS traces would also be important to analyze.

** [tickets:#721] IMMD asserted when trying to become active during failover**
**Status:** assigned
**Created:** Thu Jan 16, 2014 07:32 AM UTC by Sirisha Alla
**Last Updated:** Wed Jan 22, 2014 09:51 AM UTC
**Owner:** Mathi Naickan
The issue is seen on changeset 4733 + patches of CLM corresponding to
changesets of #220. Continuous failovers are happening when some api
invocations of IMM application are ongoing. The IMMD has asserted on the new
active leading to cluster reset.
