Table 8. 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 is overwritten.
Note: If you inserted an invalid tape cartridge (see “Data cartridges” on page 21), error code
J
or
7
displays
in the SCD. If you inserted a write-protected cartridge, or the media has read-only compatibility (see “Loading,
unloading, and write-protecting cartridges” on page 23), error code
P
displays in the SCD. In either case, the
tape drive unloads the cartridge and exits Maintenance mode after the cartridge is removed.
1. Ensure that no cartridge is in the drive.
2. Press Eject 3 times within an interval of 2 seconds. The fault LED becomes solid amber, which means that
the drive is in maintenance mode.
3. Press Eject once per second until
1
appears in the single-character display. If you cycle past
1
, continue
to press Eject until it reappears.
4. To select the function, press and hold Eject for 3 seconds. After you select the function,
1
flashes, then
C
flashes. When
C
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 write-protected cartridge, the tape drive displays a
P
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,
1
flashes and the test begins.
• The diagnostic test takes approximately 5 minutes to run. The tape drive unloads and loads 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
0
,
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 Eject twice anytime during the test. The drive
acknowledges the request by slowing the flash rate of the
F
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.
