Analyses:
1) As already commented, AMF responds to imm as soon as it sends quiesing
assignment to active SU1. the SI to locked state, before receving removal
response from amfnd.

2)Also admin state of SI state is updated before receving removal response
from amfnd.

Here it sets the admin state:

Now delete in other SU2:

'safSi=SI1,safApp=test2nApp', SU 'safSu=SU2,safSg=SG,safApp=test2nApp'
Dec 18 14:07:31.064671 osafamfd [19840:
So before removal of assignments, SI becomes locked though SG FSM is still
unstable.
So an application/admin will see TRY_AGAIN since SG is unstable for admin
operation on the SG,SU or any related entity of this SG/APP.
Marking this ticket as duplicate of #505.

** [tickets:#670] SI state is moved to locked, before assignments are removed.**
**Status:** duplicate
**Created:** Wed Dec 18, 2013 08:48 AM UTC by surender khetavath
**Last Updated:** Thu Dec 26, 2013 06:35 AM UTC
**Owner:** Praveen
changeset : 4733
model : 2n
configuration : 1App,1SG,2SUs with 4comps each, 4SIs with 1 CSI each
si-si deps configured as SI1 sponsor for SI2,3,4 resp
SU1 is active, SU2 is standby.
SU1 is mapped to pl-3 and SU2 to pl-4
saAmfSGAutoRepair=1(True)
SuFailover=1(True)
Test:
1. shutdown the SI1 ( sponsor)
2. time out in CSI RemoveCbk
SI admin state is moved to LOCKED even before the assignments are cleared.
states:
safSi=SI1,safApp=test2nApp
saAmfSIAdminState=LOCKED(2)
