The desired fix is for SMF to be able to retry the CCBs.
However,
For an optimal solution, SMF would require an indication(callback) that a CCB
was aborted with possiblility to also provide the reason for the abort! In the
absence of such an indication(callback) the SMF would have to rely on a
solution that is based on indirect interpretaion of the error codes received
for AdminOwnerSet and the CCB APIs.
Shall prepare a patch that correlates the ERR_NOT_EXIST and ERR_TIMEOUT error
codes that would be returned to the AdminOwnerSet() and CCB APIs when a CCB is
aborted.
This is possible by Either modifying the modifyInformationModel() method to
retry the immUtil.doImmOperations() for say 3 times OR breaking down
modifyInformationModel into two functions OR...!
Having said that, in my opinion i think the long term solution is for SMF and
other services to start providing service(including modifying information
model) only after they receive a CLM indication (post cluster restart) that the
node/cluster is ready (and cluster information is synched up).

** [tickets:#973] SMF to retry CCB failures when executing AU lock activation
step**
**Status:** assigned
**Milestone:** 4.4.1

Post cluster reboot, a CCB can get aborted after create operation and before
apply operation, because of a synch request, say originating from a payload.
i.e. During modify information model and set maintenance status and while in
"Executing AU lock activation step" , there is a chance that CCB was aborted
after create, but before being applied.
SMF should retry the whole CCB in the above scenario.
