Appendix A. SCSI Element Types, SCSI Addresses, and
Physical Configurations
For an overview of library partitioning and element addressing, see “Library
Partitioning and Element Addressing” on page A-3.
The following tables contain element addresses for the 2U library and the 4U
library.
Table A-1. 2U library SCSI Element Types and Element Addresses
Element Type Element Address Range
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-3.
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
librarylibrary configured with one drive and one logical partition. If a second drive
were installed, it would be located at address 257 (0x101).
With two drives installed, the library can be configured as one partition (with two
drives) or as two partitions (with one drive per partition).
When configured with two drives and one logical partition, the Element Address
assignments will be as follows: DTE assignments
v
Drive 1: 256 (0x100)
v Drive 2: 257 (0x101)
The STE assignments will be as shown in Table A-3 on page A-2.
When configured with two drives and one logical partition, the Element Address
assignments will be as follows:
