When configuring a Centera or ECS CAS partition, edit the partition to include the Process Entry Authentication file so that the Vault Store Partition can authenticate to the Centera or ECS cluster, as shown in the following VAC GUI figure.
Similarly for the connectivity test above, you will get an FP_OPERATION_NOT_ALLOWED error when you click the Test button if the IP details are correct, and you will get FP_NO_POOL_ERR if they are not.
Note: The Test button is not testing the validity of the PEA file for either the Centera or ECS system. At present, there is no way to test this except to restart the EV Storage Service and see if it logs an error in the Windows Event log.
