Single choice
Backups to a storage device fail with the following error message:
Disk storage server is down (2106)
The storage server is an OpenStorage (OST) host, and the master server and media server are both
acting as media servers under Credentials > Storage Servers in the NetBackup Administration Console.
The disk pool is in an Up state and the storage server is in a Down state. Troubleshooting confirmed the OST plug-ins on the servers are mismatched.
Which command should an administrator use to check the plug-in version installed on the servers?
