Library Firmware must be at 0080 or greater to support the LTO M8 media feature. Drive rmware must be at
HB82 or greater to support the LTO M8 media feature. Ensure that any device drivers are at the minimum level
that is required to support the library.
Note: The TL1000 Tape Autoloader supports the and later tape drives only.
For more information about media compatibility, see Chapter 5, “Media,” on page 91.
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.
