Sense data

When a drive encounters an error, it provides sense data as a response to the host. Refer to the Dell Model
ML3 Tape Library SCSI Reference?? for library sense data information. Refer to the Dell LTO Ultrium Tape
Drive SCSI Reference?? for tape drive sense data information.
In addition, you can use the Tape Diagnostic Tool (ITDT) to further examine data and determine errors.
See "The ITDT firmware update, dump retrieval and drive test tool " on page 77.

Drive Error Codes: Single-character display (SCD)

If you encounter problems while the tape drive is running, refer to "Finding event information" on page
