When saAmfSIPrefActiveAssignments is reduced, AMFD removes assignments from higher ranked SU when siranked su is not configured.
Steps to reproduce:
1) Bring attached application up on one controller.
2) The only SI is assigned to three SUs. Three SUs have different SURanks. Pref active assignments for SI is 3.
3) Reduce pref active assignment for the SI by running following command:
immcfg -a saAmfSIPrefActiveAssignments=2 safSi=NWay_Active,safApp=NWay_Active
4)Since pref active assignments is reduced by 1, AMFD sends quiesced and removal of assignment to SU2.
5)SU2 has rank2. Assignments should be removed from SU3 which has rank 3.
Assignments before reducing pref active assignmets:
safSISU=safSu=SU1\,safSg=NWay_Active\,safApp=NWay_Active,safSi=NWay_Active,safApp=NWay_Active
saAmfSISUHAState=ACTIVE(1)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
safSISU=safSu=SU2\,safSg=NWay_Active\,safApp=NWay_Active,safSi=NWay_Active,safApp=NWay_Active
saAmfSISUHAState=ACTIVE(1)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
safSISU=safSu=SU3\,safSg=NWay_Active\,safApp=NWay_Active,safSi=NWay_Active,safApp=NWay_Active
saAmfSISUHAState=ACTIVE(1)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
Assignments after reducing pre active assignments:
safSISU=safSu=SU1\,safSg=NWay_Active\,safApp=NWay_Active,safSi=NWay_Active,safApp=NWay_Active
saAmfSISUHAState=ACTIVE(1)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
safSISU=safSu=SU3\,safSg=NWay_Active\,safApp=NWay_Active,safSi=NWay_Active,safApp=NWay_Active
saAmfSISUHAState=ACTIVE(1)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
Similar issue in N-Way model also when SiPrefStandbyAssignment is reduced. Also AMFD is not checking the HA state of the susi and tries to delete active susi and crashes:
