Configuring the NetBackup Media Server
Step 2: Add Credentials for the Data Domain System
When you add the credentials, NetBackup:
• Saves the credentials so the media server can log onto the storage server.
• Configures the media server as a data mover. A data mover is an entity that moves data
between the primary storage (the NetBackup client) and the storage server.
NetBackup does not monitor connectivity between data movers and storage servers. However,
when you add the credentials on each media server, NetBackup configures and maintains an access
path between the media server and the storage server.
Add credentials for each registered Data Domain storage server with which this media server needs
to communicate using the tpconfig command:
Important Run the tpconfig command on each media server that needs to access a Data
Domain storage server.
# tpconfig
-add -storage_server dd22
-stype DataDomain
-sts_user_id username
-password password
If the add credentials operation fails, do the following:
1. Look for authentication messages in the ddfs.info file on the Data Domain system.
2. Ensure that the username and password match the ones on the Data Domain system.
Use the ost show user-name command on the Data Domain system to check the
username.
3. To change the username and password, enter a command line such as this:
# tpconfig -update
-storage_server dd22
-stype DataDomain -sts_user_id username
-password password
4. Restart the nbrmms process:
# nbrmms
