To be added to the PMAC hardware inventory, OA hardware must be physically installed and in service. Then OAs are added to the enclosure configuration. PMAC is provisioned with the OA IP address of the active OA and the standby OA. If a failure occurs, the standby OA automatically takes over the role of active OA and PMAC automatically uses the new OA.
Caution:
Both OA IP addresses must be installed, the OA IP address must be configured in PMAC using the Add Enclosure or the Edit Enclosure command. If this configuration is not performed, PMAC does not have a connection to the newly active OA after an OA failover, and consequently, has no knowledge of the system hardware.Any changes to the configuration cause the enclosure to be rediscovered by PMAC.
