About resolving multiple names for a single server
For every media server, you should add an entry on the Alternate Media Server Names tab of the Vault Management Properties dialog box. At a minimum, there should be, for each media server, an entry that contains both the abbreviated name and the fully qualified name. Also add any other names by which a media server has ever been known. Taking this action avoids a number of problems. For example, if you do not list alternate names for media servers, some images may not be recognized as a match for the criteria entered in the Choose Backups tab of the Profile dialog box and may therefore not get vaulted.
If you have multiple NIC cards in your server, make sure that the server name associated with each NIC card is listed in the Alternate Media Server Names tab when you configure a profile.
See Alternate Media Server Names tab (Vault Management Properties).
Note:
Alternate media servers apply to NetBackup Enterprise Server only.
