Symantec recommends that you get and save the storage server configuration file.

If you get the configuration of a storage server that is down or unavailable because of a disaster, NetBackup returns a template configuration file.

See About the deduplication storage server configuration file.

install_path\NetBackup\bin\admincmd\nbdevconfig -getconfig -storage_server sshostname -stype PureDisk -configlist file.txt

For sshostname, use the name of the storage server. For file.txt, use a file name that indicates its purpose.
