About OpenStorage server credentials
When you configure a storage server in the Storage Server Configuration Wizard, you configure its credentials.
NetBackup does the following:
Saves the credentials so the media servers 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 each media server you select as a data mover.
NetBackup does not monitor connectivity between data movers and the storage server. However, when you configure the credentials, NetBackup configures and maintains an access path between the media server and the storage server.
If the storage server does not require logon credentials, you must enter dummy credentials so that NetBackup configures the media servers as data movers.
