Deleting an MSDP storage server

If you delete a deduplication storage server, NetBackup deletes the host as a storage server and disables the deduplication storage server functionality on that media server.

NetBackup does not delete the media server from your configuration. To delete the media server, use the NetBackup nbemmcmd command.

Deleting the deduplication storage server does not alter the contents of the storage on physical disk. To protect against inadvertent data loss, NetBackup does not automatically delete the storage when you delete the storage server.

If a disk pool is configured from the disk volume that the deduplication storage server manages, you cannot delete the deduplication storage server.

Warning:

Do not delete a deduplication storage server if its storage contains unexpired NetBackup images; if you do, data loss may occur.

To delete an MSDP storage server

  1. In the NetBackup Administration Console, expand Media and Device Management > Credentials > Storage Server
  2. On the Edit menu, select Delete.
  3. Click Yes in the confirmation dialog box.
