The ralus.cfg format contains three components. The first component (A) is a required string.
The second component is a unique identifier followed by an equal sign (=). A unique identifier can consist of sequential numbers, letters or alpha-numeric characters. For example: 1, 2, 3 or A, B, C. You can also use AA, BB, CC, or A1, A2, B1, B2. Whatever unique identifier you decide to use must be unique if you list multiple Backup Exec media servers in the ralus.cfg file.
The third component of the ralus.cfg format is the actual Backup Exec media server IP address or its naming-service accessible name. For example, a DNS name, computers file name, or NIS name). When entering this information, do not use spaces.
Editing a ralus.cfg file can be done using any UNIX text editor.
