5 LTO Drive Support
The SL3000 supports certain versions of LTO drives.
- HP LTO generations 3, 4, 5, and 6
- IBM LTO generations 3, 4, 5, 6, 7, 8 and 9
Note:
LTO-8 and above can read and write one generation back. LTO-7 and below can read two generations back and write one generation back. For best capacity and performance, always use cartridges of the same generation as your drives.

LTO SCSI Updates
The SL3000 includes SCSI updates for LTO drives.
Behavior During LTO-9 Cartridge Calibration
This update applies to the SL3000 SCSI Reference, Chapter 2, "SCSI Operation and Configuration".
The IBM LTO-9 drive performs a cartridge calibration process when a new LTO-9 tape is loaded in the drive. This calibration takes an extended length of time. In some cases, up to two hours.
- The SCSI interface returns
GOODstatus to the host as soon as the library determines that the IBM LTO-9 drive is calibrating the tape.- Normally, the library waits until the tape drive indicates the tape is loaded and the drive is ready to accept SCSI commands on the data path.
- During calibration, the drive interface returns Not Ready, Becoming Ready to SCSI commands on the data path: Sense Key = 02, ASC = 04h, ASCQ = 01h.
- If the host issues a
dismountcommand while the drive is calibrating, the library returns a Check Condition, Illegal Request, Medium Not Present, Drive Not Unloaded: Sense Key = 05h, ASC = 3Ah, ASCQ = 00h.
Read Element Status LTO Additions
This update applies to the SL3000 SCSI Reference, Chapter 3, "SL4000 SCSI Commands".
The Element Descriptor for Read Element Status (B8h) includes new Media Type and Transport Type values:
- Media Type additions:
If the Media Domain is 4Ch (L):
- 9 = The element contains a 18 TB Generation 9 LTO cartridge.
- *R = The element contains a 9 TB Generation LTO 7 cartridge with an M8 label. The cartridge is only compatible with an IBM LTO-8 tape drive. The SCSI interface returns LR for the domain and type rather than the M8 physically on the label.
- Z = The element contains a 18 TB Generation 9 LTO WORM cartridge.
- Transport Type additions:
If the Media Domain is 4Ch (L):
- 46h = IBM Generation 9 LTO drive.
