SCSI Basics
Installation and Operation
157
If you have one tape drive installed, the library uses two SCSI IDs,
one for the library itself and one for the tape drive. If you have
two drives installed, the library uses three IDs. Separate IDs allow
the library and tape drives to operate as independent devices,
receiving different sets of SCSI commands from the host.
