The ECS CAS partition is configured in the EV VAC the same way that Centera partitions are configured. However, the different behavior between Centera and ECS CAS when handling connections using the Anonymous Profile will cause different results during configuration.
Both the ECS CAS and the Centera partitions are initially configured when a new Vault Store is created or when a new partition is added to an existing Vault Store.
To configure the IP connectivity for the partition, do the following.
At this point, test the connection by clicking Test.
Note that there is no PEA file detailed in this GUI so far. When you click the Test button, the EV VAC is using the Anonymous Profile to connect to the Centera/ECS.
This is just a network connectivity test which normally results in the following response from a Centera cluster.
With ECS, access with the anonymous profile is not allowed and results in an error.
This occurs because the EV VAC is not using a PEA file to authenticate with the EV Access Profile (ECS User). The ECS displays that the VAC managed to connect to the ECS system with the IPs specified, but is returning FP_OPERATION_NOT_ALLOWED because anonymous access is disabled.
The EV VAC interprets this error as Centera not found at IP Address… which is not correct. If the ECS was not accessible at all, the EV VAC would get the following error from the CAS SDK:
The FP_NO_POOL_ERR error means that the IP connectivity details are wrong, and the CAS SDK timed out on the connection attempt.
