saAmfSgtDefCompRestartMax is SG level attribute and there is not
attribute in SaComp to configure SU restart.
From 4.4 onwards saAmfSUfailover is fully supported.
So if saAmfSUFailover=1 and saAmf SGAutoRepair=1 then:
1)For C1 saAmfCompDisableRestart=0 and recovery=2: if the component
faults, it will be restarted.
2) For C2 saAmfCompDisableRestart=1 and recovery=2 (or
saAmfCompDisableRestart=0 and recovery=3 ): if this component
faults then, fault will be escalated to SUFailover. In SU failover,
AMF will clean up both components C1 & C2 and SU will be disabled .
After successful
cleanup. AMF will repair the SU (saAmf SGAutoRepair=1) in which SU
will be enabled again. Now SU will reinstantiated and will be assigned
fresh assignments.
It is not same as surestart because AMF failovers the assignments
from the failed SU to another standby or spare SU. So please check if this
configuration can solve the problem.
