If a NetBackup site has multiple master servers, you can configure the systems so that multiple servers can be accessed from one NetBackup Administration Console.
A host running NetBackup Enterprise Server or NetBackup Server may use the Change Server command to access another host. The other host must run either NetBackup Enterprise Server or NetBackup Server.
