This property specifies the media ID prefix to use in media IDs when the unlabeled media is in nonrobotic drives. The prefix must be one to three alpha-numeric characters. NetBackup appends numeric characters. By default, NetBackup uses A and assigns media IDs such as A00000, A00001, and so on.

For example, if FEB is specified, NetBackup appends the remaining numeric characters. The assigned media IDs become FEB000, FEB001, and so on. (Note that this numbering does not work with the Configure Volumes wizard).
