IBM TS2900 - Media Overview; Logical Unit Number (LUN) Scanning

Media
The TS2900 Tape Autoloader uses Ultrium tape cartridges that provide up to 12 TB native capacity (up to
30 TB with 2.5:1 hardware data compression) for Ultrium 8 tape drives.
For more information on native data capacity, see Table 3 on page 2.

Library Firmware must be at 0080 or greater to support the LTO M8 media feature. Drive firmware must be at
HB82 or greater to support the LTO M8 media feature. Ensure that any IBM device drivers are at the minimum
level that is required to support the library.
Note: The TS2900 Tape Autoloader supports the Ultrium 3 (3572-S3H) and laterTape Drives only.
For more information about media compatibility, see “Media” on page 107.
Logical Unit Number (LUN) scanning
The TS2900 Tape Autoloader uses a single SCSI ID and dual LUNs to control the tape drive (LUN 0) and
library accessor (LUN 1). The library requires a Host Bus adapter (HBA) that supports LUN scanning. If
it is not enabled, your host system cannot scan beyond LUN 0 and fails to detect the library. It sees only
the tape drive.
Important: Some HBAs, such as RAID controllers, do not support LUN scanning.
Location coordinates and element addresses
The TS2900 Tape Autoloader incorporates IBM’s patented high-density (HD) slot technology, which
allows multiple cartridges to be stored in a tiered architecture. The depth of a cartridge location in a
high-density slot is known as a tier. High-density slots are designed to contain multiple cartridges in
Tiers 1 and 2.
