#1 I have applied patches #1 to #4 only. With this patches(not having patch #6), I thought to have passed most of the following tests, but they got failed(Listed below).
I could not test other scenarios (including alarms and notifications), because
I haven't applied patch #6. I think there should be a simple patch replacing
patch #6, which handles transient state as 'reboot the node' if Amf finds SUSI
in transient state on that node.
I am attaching a concept patch(assignment_recovery.patch), which pass some of
the scenarios and we are testing and enhancing it.
As Praveen has suggested that we need to reboot the node which is undergoing in
transient state to make it simple.
This patch reduces complexity and maintainability.
So, ACK for patch #1-#4 along with the attached patch.
Please note that the attached patch has been created on patch #6 of yours, so
please apply #1 to #4 and then #6 and then the attached patch.
Currently the patch is for 2N red model. We are working to make for Nway Act
and No red model (and possibly for Nway and NpM), we will publish it tomorrow.
TC #1:
Configuration(Comp recovery is comp failover, saAmfSutDefSUFailover as false)
and logs attached(TC 1) in the ticket.
1. Start SC-1, PL-3 and PL-4. SU1 Act on PL-3 and SU2 Standby on SC-2.
2. Stop SC-1 and kill demo. It goes for comp failover as configured. Ideally,
node should reboot.
3. Start SC-1. After cluster timer expires, PL-4 got the following error
messages:
Mar 2 08:01:15 PM_PL-4 osafamfnd[20050]: CR SU-SI record addition failed, SU=
safSu=SU2,safSg=AmfDemo,safApp=AmfDemo1 : SI=safSi=AmfDemo,safApp=AmfDemo1
Mar 2 08:01:15 PM_PL-4 osafamfnd[20050]: CR SU-SI record addition failed, SU=
safSu=SU2,safSg=AmfDemo,safApp=AmfDemo1 : SI=safSi=AmfDemo1,safApp=AmfDemo1
There is no assignment given for SU1. SU2 has Standby assignments:
safSISU=safSu=SU2\,safSg=AmfDemo\,safApp=AmfDemo1,safSi=AmfDemo,safApp=AmfDemo1
saAmfSISUHAState=STANDBY(2)
saAmfSISUHAReadinessState=READY_FOR_ASSIGNMENT(1)
safSISU=safSu=SU2\,safSg=AmfDemo\,safApp=AmfDemo1,safSi=AmfDemo1,safApp=AmfDemo1
saAmfSISUHAState=STANDBY(2)
Other problems: a.) Further command for locking SU1/SU2 fails in SG unstable
error.
b.) Immlist if SU2 gives the below result,
Standby assignment it prints as 4, which is wrong:
saAmfSUNumCurrStandbySIs
SA_UINT32_T 4 (0x4)
saAmfSUNumCurrActiveSIs
SA_UINT32_T 0 (0x0)
c.) Even if SC-2 joins, and you do
failover/switchover of SC-1, still same as above.
TC #2: After execution of TC #1, stop PL-3. In worst case, SU2 assignment
should change to Act, which is not happening. After stopping of PL-4 also, the
same problems as TC #1. logs attached(TC 2).
TC #3: After TC #2, start PL-3 and start SC-2.
SU1 is instantiated, but no assignment and the same problem as
above.
When stop PL-4, SU1 gets assignments, the following logs comes
at SC-2:

Start PL-4, SU2 gets Standby assignments and everything works fine after that.
TC #4: Similar problems exist in the following test cases:
a.) Configuration same as TC #1 except saAmfSutDefSUFailover as true.
After killing demo, PL-3 went for reboot.
But the problem is the same as shown in TC #1, TC #2 and TC #3.
b.) Configuration same as TC #1 except with saAmfCtDefRecoveryOnError as 2
and saAmfCtDefDisableRestart as 1.
But the problem is the same as shown in TC #1, TC #2 and TC #3.
c.) Configuration same as TC #1 except with saAmfCtDefRecoveryOnError as 2
and saAmfCtDefDisableRestart as 1 and saAmfSutDefSUFailover as 1.
After killing demo, PL-3 went for reboot.
But the problem is the same as shown in TC #1, TC #2 and TC #3.
TC #5: Configuration same as TC #1 except with saAmfCtDefRecoveryOnError as
2. Configuration and logs(TC 5) attached in ticket.
1. Start SC-1, PL-3 and PL-4. SU1 Act on PL-3 and SU2 Standby on SC-2.
2. Stop SC-1 and kill demo. It goes for comp restart as configured.
3. Start SC-1. After SC-1 comes up and before cluster timer expires, stop PL-3:
Even if PL-3 is stopped(see below PL-3 is not available), SU1 is still having
Act assignment and SU2 is having Standby assignment:

TC #6: After TC #5, start PL-3:
SU1 is not given any assignment (may be because it exists in Amfd db):

This is obvious because, Amfnd doesn't have any assignment.
SU1 admin state is locked, but SUSI is being shown on SU1.
TC #8: After TC #7:
Lock SU1, it throws error:
Admin operation is already going on (su'safSu=SU1,safSg=AmfDemo,safApp=AmfDemo1
TC #9: Same as TC #6 except Configure saAmfCtDefRecoveryOnError as Node
Switchover/Failover/Failfast.
The problem reported in TC #4 exists.
