Error Message

In versions prior to EV 12.1 it was required that a NetApp FSA target was configured in a specific way. NetApp C-Mode allows the separation of data and management traffic to be configured on separate Logical Interfaces (LIFs), however, Enterprise Vault (EV) mandated that the LIF needed to have both data and management roles enabled on it. In version 12.1 this is no longer a restriction and it can now support a configuration where the LIF does not have both management and data roles. As part of this new feature it is necessary to perform checks when upgrading to 12.1 to ensure that an administrator cannot add the same NetApp target using a different management LIF. This is achieved by using the UUID value from NetApp which is a unique value assigned to every Storage Virtual Machine (SVM).

After the upgrade, the FPolicy Server populates the Vserver UUIDs on initialization. If, for any reason, the Vserver UUID of any of the NetApp C-mode targets is not populated the VAC displays the warning message in the VAC when one tries to add an additional NetApp C-Mode File Server. These UUID values can be obtained via the command:

vserver -show -fields -uuid

This is an example output:

There could be multiple reasons why the UUID value cannot be obtained, such as a communication problem or the Vserver was off line when the NetApp placeholder service was initializing. To assist in finding the root cause, the following advice is given:

1. Firstly identify which UUID or UUIDs have not been populated. These values are stored in the EnterpriseVaultDirectory SQL database, within the NetAppClusterModeFileServerConfig table.
2. Open the NetAppClusterModeFileServerConfig table.
3. Identify which Vservers do not have a value within the VserverUUID column. This is the reason why the warning is appearing.
4. Check that the Vserver is up and running.
5. If the Vserver is up and running, restart the Enterprise Vault Admin Service which will trigger the initialization process.

When adding a NetApp FSA target in the Vault Administration Console the following Warning is shown:-

Cannot find the Vserver UUID for one or more C-Mode Vservers, Addition of a NetApp C-Mode Vserver that has already been configured can result in inconsistencies in File System Archiving
