The disk appliance storage server may require logon credentials. The NetBackup media servers that function as data movers require the credentials for storage access.
When you configure a storage server, you also configure the credentials in the Storage Server Configuration Wizard. If the storage server does not require logon credentials, you must enter dummy credentials so that NetBackup configures the media servers as a data mover.
When you configure the credentials, NetBackup does the following:
Saves the credentials so the media server can log into the storage server.
If the storage server is also an NDMP FSE host for direct to tape operations, they both must have the same logon credentials.
Configures the media server as a data mover.
NetBackup does not monitor connectivity between data movers and storage servers. However, when you configure the credentials, NetBackup configures and maintains an access path between the media server and the storage server.
