Logical Unit Number (LUN) scanning

The TL1000 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 TL1000 Tape Autoloader incorporates 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.
Note: Each column has a spring-loaded mechanism that pushes a tape cartridge into Tier 1 when it is the
only cartridge in that column. A single cartridge in a column takes on the Tier 2 element address even
though it is physically in Tier 1.
