HP Instant Capacity Version 10.x Release Notes (5900-2363, September 2012)

Connection is lost between GM and Member, in case of OA failover
During OA failover (if ENCLOSURE_IP_MODE is not enabled on the member OA), GM does not
know the hostname or the IP Address of the new Active OA. To resolve this issue:
1. Delete the certificate from cimtrust (in AGM, SGM).
2. Add a member (active OA) with new IP or hostname.
3. Execute icapmanage -s on the GM to check for member reachability.
