Member shows alert while in STARTED state, all hosts are in ACTIVE state with no alerts

This symptom observed occurs as a follow on from the scenario "Member WAITING_FOR_FAILBACK, alert, corresponding host(s) is in INACTIVE state with alert". The output of the db2instance -list command shows a member with an alert while its state is STARTED. All hosts are in ACTIVE state with no alerts.

This is a sample output from the db2instance -list command showing a three member, two cluster caching facility environment:

Member 0 still has its alert flagged as an indicator to the administrator to investigate the problem that occurred on hostB that prevented the member from performing a restart light.
Note: The hostB problem is detailed in the parent topic Member WAITING_FOR_FAILBACK, alert, corresponding host(s) is in INACTIVE state with alert.
