Analysis:
1)AMFD sends quiesced assignment for all SIs to SU1.
2)AMFD received SU level quiesced response for SU1, SU level
active sent to SU2.
status of counters:

3)AMFD received disabled event for Su2 , AMF sent SU level delete in SU1. Also
SUSIs are
deleted in SU2.
For deletion counters are updated only for active and standby states after
receving the
response.
Since all the SUSIs are in modeify state in SU2, counters are not updated for
any SIs
while deleting SUSIs in SU2. Relevent AMF code
if (susi->fsm == AVD_SU_SI_STATE_MODIFY) {
/* Dont delete here, if i am in modify state.
only happens when active -> qsd and standby rebooted
*/
} else if ((susi->fsm == AVD_SU_SI_STATE_ASGND) || (susi->fsm
==
AVD_SU_SI_STATE_ASGN)){
if (SA_AMF_HA_STANDBY == susi->state) {
avd_su_dec_curr_stdby_si(susi->su);
avd_si_dec_curr_stdby_ass(susi->si);
} else if ((SA_AMF_HA_ACTIVE == susi->state) ||
(SA_AMF_HA_QUIESCING == susi->state)) {
avd_su_dec_curr_act_si(susi->su);
avd_si_dec_curr_act_ass(susi->si);
}
}
}
4)AMF received enabled event for SU2, AMF sends instantiation event to SU2.
5)AMFD received delete response for SU1, SUSIs are deleted and SG made stable.
6)AMFD received enabled event for instantiation for SU2, freshly assigned
active for all
SIs in SU2.
In this case status of active counters for all SIs:
Dec 19 12:33:36.727995 osafamfd [6180:si.cc:1295] TR safSi=SI1,safApp=test2nApp
saAmfSINumCurrActiveAssignments=2
Dec 19 12:33:36.730463 osafamfd [6180:si.cc:1295] TR safSi=SI2,safApp=test2nApp
saAmfSINumCurrActiveAssignments=2
Dec 19 12:33:36.732337 osafamfd [6180:si.cc:1295] TR safSi=SI3,safApp=test2nApp
saAmfSINumCurrActiveAssignments=2
Dec 19 12:33:36.734698 osafamfd [6180:si.cc:1295] TR safSi=SI4,safApp=test2nApp
saAmfSINumCurrActiveAssignments=2
Here counters went beyond their 2N model limit for all the SIs
7)AMFD received active assignments for SIs.
8)Unlock of Su1 leads to successful standby assignment in SU1 for all SIs.
The issue is same as #666 with the difference that in #666 SI dep is configured
and
shutdown operation was performed instead of lock. In both the cases quiescing
or quiesced
assignments were successful, which means SUSIs are quiesced and thus SU is now
in locked state.
After this both shutdown and lock operation behaves similarly i.e active
assignment in SU2 and removal of assignment in Su1. Also in both the issues
fault occurred during active assignment.
This makes both of these issue similar and thus fix for #666 will also be
applicable for #678.
Based on this analysis, marking #678 ticket as duplicate of #666.
Also #666 will be updated to be reproducible without SI dependency and with
lock operation.
