You can configure multiple paths from the storage system to access tape drives in a tape library. If one path fails, then the storage system can use the other paths to access tape drives without having to immediately repair the failed path. This ensures that tape operations can be restarted.
Tape drives and media changers are assigned to LUN groups (set of LUNs that share the same initiator path set) in a tape library. All tape drives of a LUN group must be available for backup and restore operations on all multiple paths.
