For information on the latest versions of firmware, see the Dell support website at support.dell.com. 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. 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. Table 3. Diagnostic and Maintenance Function Codes and Descriptions Function Code 1 - Run Tape Drive Diagnostics Causes the tape drive to run self tests. Attention: Insert only a scratch data cartridge for this test. Data on the cartridge will be overwritten. 1. Ensure that there is no cartridge in the drive. 2. Press the eject button three times within an interval of 2 seconds. The fault LED becomes solid amber, which means that the drive is in maintenance mode. 3.

To select the function, press and hold the eject button for 3 seconds. After you select the function, flashes, the drive runs diagnostics for approximately 90 seconds, then flashes. When flashes, the drive is waiting for a cartridge. 5. Within 60 seconds, insert a scratch data cartridge that is not write-protected. NOTE: If you wait longer than 60 seconds to load a cartridge, the drive automatically exits maintenance mode. If you insert a writeprotected cartridge, the tape drive displays a and retains the cartridge until it is manually ejected. When the cartridge is ejected and removed, the tape drive exits maintenance mode. After you insert the cartridge, flashes and the test begins. ¡ 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
