Based on the current implementation (functional) scope holding by different
services of OpenSAF, introducing such functional behaviour into FM module seems
more appropriate to handle the scenario. FM is been already in MDS subscription
with AMFD, AMFND etc.
However, this proposal is introducing a new behaviour in OpenSAF startup, hence
this ticket shall need categorize as enhancement rather than as defect and can
target for 5.2 release.

** [tickets:#2151] osaf: system in not in correct state during Act controller
comming up**
**Status:** unassigned
**Milestone:** 5.2.FC
**Created:** Mon Oct 31, 2016 10:54 AM UTC by Nagendra Kumar
**Last Updated:** Tue Nov 08, 2016 05:03 PM UTC
**Owner:** nobody
Steps to reproduce:
1. Start two controllers(SC-1 Act, SC-2 Standby) and two paylods. Configure 50
components on SC-2 and unlock them. Keep 1 sec delay in each component stop
script.
2. Stop SC-1 and after that, stop SC-2.
3. During SC-2 is going down, start SC-1.
Observed behaviour:
Since components are taking time in stopping all components during 'opensad
stop' of SC-2, Amfnd hasn't exited. But, all middleware components assignments
are stopped. Only Amfnd and Amfd is alive with few more components to stop.
But SC-1 has come up till Amfd and since two Amfd is Act now, so SC-2 Amfd
exits by saying "Duplicate ACTIVE detected, exiting".
Till this time, services states including Amfd is in bad state as they couldn't
differentiate whether it is headless state or failover. This is true also as
the system is in half middle of headless and failover.
Expected behaviour
In my view:
FMS should stop and shouldn't proceed if peer is going down. i.e. FMS should
figure out on SC-1 that the peer system is going down. And should allow SC-1
only if all services are down i.e. it gets node down (may be cb->immd_down &&
cb->immnd_down && cb->amfnd_down && cb->amfd_down && cb->fm_down).
