Since Spec is not very clear about saAmfSGNumPrefInserviceSUs, here is the
implementation specifics:
1. Amf should instantiate SUs(locked or unlocked) as per
saAmfSGNumPrefInserviceSUs.
2. Amf should give preference to instantiate to unlocked SU than locked SU. For
example:
Consider the below configuration:
2N, 3 SUs, saAmfSGNumPrefInserviceSUs as 2. SU1 Act, SU2 Std and SU3 is also
unlocked, but it is uninstantiated.
2.1 When SU1 is locked,
a.) SU1 assignments are removed and SU2 becomes Act.
b.) Since SU1 is now Out of service, Amf should start SU3 as it is
unlocked. But
it can't exceeds more than 2 SUs. So, it prefers to terminate
SU1 and instantiate SU3.
c.) After SU3 becomes instantiated, Amf assigns Standby role.
So, as of now, SU2 and SU3 are instantiated and assigned. SU1 is locked and
uninstantiated.
Now, even if SU1 is unlocked, Amf will not instantiate SU1 as there are
already 2 Sus instantiated.
If possible, Amf should try to pick higher rank SU to instantiate and lower
rank SU to terminate.
More example of such cases has been provided in the patch review email.

Reference to Devel Ticket #2794, is in Fixed state but still reproducible.
Change Set:4241 with patches 2794, 3117, 367, 43,161, 222, 273, 236
Configuration: 2N redundency model.
4SU, 1 COMP each,2SI
saAmfSGNumPrefInserviceSUs=2
Steps to Reproduce:-
1.Unlock-in and Unlock all the SUs.
SU1 UNLOCKED| ENABLE| IN-SERVICE| INSTANTIATED
SU2 UNLOCKED| ENABLE| IN-SERVICE| INSTANTIATED
SU3 UNLOCKED| ENABLE| OUT-OF-SERVICE| UNINSTANTIATED
SU4 UNLOCKED| ENABLE| OUT-OF-SERVICE| UNINSTANTIATED
2.SU1 got Active assignment and SU2 got STANDBY .
3.LOCK SU1 with ADMIN operation .
4.SU2 became ACTIVE But SU3 didnot INSTANTIATE,And No STANDBY assignment to any
SU.
