Selecting a Diagnostic or Maintenance Function
The tape drive can run diagnostics, test write and read functions, test a suspect tape cartridge, and perform other diagnostic and maintenance functions. The drive must
be in maintenance mode to perform these functions. To place the drive in maintenance mode and select a diagnostic or maintenance function, see
.
Table 3. Diagnostic and Maintenance Function Codes and Descriptions
NOTICE: When updating firmware, do not power off the tape drive until the update is complete, or the firmware may be lost.
NOTE: The host interface on this tape drive is Serial Attached SCSI (SAS). This interface presents SCSI protocol to the tape drive. In this User's Guide,
references to SCSI relate to SCSI protocol, not the serial interface that it is transmitted over.
NOTE: You cannot perform maintenance functions concurrently with read or write operations. While in maintenance mode, the tape drive does not accept
SCSI commands from the system. Close all tape drive applications before entering maintenance mode.

The diagnostic test takes approximately 5 minutes to run. The tape drive will unload and load the cartridge during the test. Do not try to remove the
cartridge when it unloads the first time. Wait for the test to complete.
¡
If the diagnostic completes successfully, the cartridge ejects, the single-character display flashes a
, then goes blank, and the drive exits maintenance
NOTE: If you wait longer than 60 seconds to load a cartridge, the drive automatically exits maintenance mode. If you insert a write-
protected cartridge, the tape drive displays a

removed, the tape drive exits maintenance mode.
