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 .
Table 3. Diagnostic and Maintenance Function Codes and Descriptions
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.
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. Press the eject button once per second until appears in the single-character display. If you cycle past , continue to press the eject button until
it reappears.
4. 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.
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 mode.
¡ If the diagnostic fails, the fault LED flashes and an error code displays. When the cartridge is manually ejected and removed, the tape drive
automatically exits maintenance mode.
¡ To halt the diagnostic and terminate the test, press the eject button twice anytime during the test. The drive acknowledges the request by
slowing the flash rate of the on the single-character display from twice per second to once per second. The tape drive rewinds and unloads
the cartridge and then exits maintenance mode.
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 and retains the cartridge until it is manually ejected. When the cartridge is
ejected and removed, the tape drive exits maintenance mode.
Function Code 2 — RESERVED (Service Function)
Function Code 3 — RESERVED (Service Function)
Function Code 4 — Force a Dump of Vital Data to Tape Drive Memory
Causes the tape drive to perform a collection (or dump) of vital technical data and save it to drive memory. (A drive dump is also known as a save of the
firmware trace.)
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. Press the eject button once per second until appears in the single-character display. If you cycle past , continue to press the eject button until
it reappears.
4. To select the function, press and hold the eject button for 3 seconds. After you select the function, displays, followed by . The single-character
display then goes blank, and the tape drive exits maintenance mode.
You can also perform this operation when the tape drive is in normal operating mode. Simply press and hold the eject button for 10 seconds.
NOTICE: When an error code is displayed in maintenance mode, the tape drive also displays a dot to remind you that a dump already exists. If
you perform Function Code 4, it will overwrite the dump and cause the error information to be lost.
Function Code 5 — RESERVED (Service Function)
Function Code 6 — RESERVED (Service Function)
Function Code 7 — RESERVED (Service Function)
Function Code 8 — RESERVED (Service Function)
Function Code 9 — Display Error Code Log
Causes the tape drive to display the last ten error codes, one at a time. (The codes are ordered; the most recent is presented first and the oldest (tenth) is
presented last.)
To view the drive error log:
1. Ensure that there is no cartridge is in the drive.
2. Within a 2 second interval press the eject button three times. The fault LED becomes solid amber, which means that the drive is in maintenance
mode.
3. Press the eject button once per second until appears in the single-character display.
4. Press and hold the eject button for 3 seconds to view the most recent error code.
