For an overview of library partitioning and element addressing, see “Library
Partitioning and Element Addressing” on page A-2.
The following tables contain element addresses for the 2U library and the 4U
library.

Media Transport (Accessor) Element (MTE) 1 (0x01)
I/O Station Element (IEE) 16 (0x10)
Data Transfer (Drive) Element (DTE) 256 (0x100), 257 (0x101)
Storage Elements (STE) 4096 (0x1000) - 4117 (0x1015)
Table A-2. 4U library SCSI Element Types and Element Addresses
Element Type Element Address Range
Media Transport (Accessor) Element (MTE) 1 (0x01)
I/O Station Elements (IEE) 16 (0x10), 17 (0x11), 18 (0x12)
Data Transfer (Drives) Elements (DTE) 256 (0x100), 257 (0x101), 258 (0x102, 259
(0x103)
Storage Elements (STE) 4096 (0x1000) - 4139 (0x102B)
2U Library I/O Slot, Storage Slots and Drive Slot Element Addresses
and Physical Locations
For an overview of library partitioning and element addressing, see “Library
Partitioning and Element Addressing” on page A-2.
The following table contains the physical location and SCSI element address
(decimal and hexadecimal) of the I/O slot, storage slots, and drive slot in the 2U
library containing only one drive. If a second drive were installed, it would be
located at address 257 (0x101).
