Physical and logical addresses of drives
The library assigns each tape drive a unique address to indicate its physical and logical location.
The library assigns each tape drive a unique address to indicate its physical location, which is shown in
Figure 22 on page 15. The physical numbering is bottom up on all drives. This information is shown on
the Drives page of the Management GUI.
Figure 22. Physical numbering of drives
The library assigns each tape drive a SCSI element address that consists of a value that defines a logical
location in the library to the SCSI interface. It is assigned and used by the application when the host
server processes SCSI commands. The SCSI element address for a drive is unique to the location of the
drive. It does not vary based on other drives in the library. See “Library partitioning” on page 59.
