then: Ultrium Tape Drive Drive Empty v If an error is detected the test stops, 6 or 7 appears in the single-character display (another code could appear), and the following message displays: ERROR! Drive/Media Error To determine the error, locate 6 or 7 in Table 8 on page 55. The drive unloads the tape cartridge, exits maintenance mode, and displays the following message: Ultrium Tape Drive Drive Empty To clear the error, turn the power off, then on again. Function Code F: Fast Read/Write Test Function Code F performs tests to ensure that the drive can read from and write to tape. The diagnostic takes approximately 5 minutes to complete and loops continually until you halt it. To halt the diagnostic, press the unload button. The diagnostic will continue to the end of its loop, then stop. The drive then exits maintenance mode. The Fast Read/Write Test performs fewer tests than the Run Tape Drive Diagnostics test (Function Code 1). Attention: For this test, insert only a scratch (blank) data cartridge or a cartridge that may be overwritten. During the test, the drive overwrites the data on the cartridge. 1. Make sure that no cartridge is in the drive. 2. Make sure that the following message appears on the message display (you may need to turn the power off, then on again for the message to appear): Ultrium Tape Drive Drive Empty 3. Within two seconds, press the unload button 3 times. The status light becomes solid amber and the following message displays (indicating that the tape drive is in maintenance mode): Maint Mode: Select Exit Maint Mode Note: If a cartridge is in the tape drive, it will eject the first time that you press the unload button and the drive will not be placed in maintenance mode. To continue placing the drive in maintenance mode, perform the preceding step. 4. Press the unload button once per second until F appears in the single-character display and the following message displays. (If you cycle past the desired code, press the unload button once per second until the code redisplays.) Appendix B. Diagnostic and Maintenance Functions 77

v
If an error is detected the test stops,
6
or
7
appears in the single-character
display (another code could appear), and the following message displays:
ERROR!
Drive/Media Error
To determine the error, locate
6
or
7
in Table 8 on page 55. The drive unloads
the tape cartridge, exits maintenance mode, and displays the following
message:
Ultrium Tape Drive
Drive Empty
To clear the error, turn the power off, then on again.
Function Code F: Fast Read/Write Test
Function Code F performs tests to ensure that the drive can read from and write to
tape. The diagnostic takes approximately 5 minutes to complete and loops
continually until you halt it. To halt the diagnostic, press the unload button. The
diagnostic will continue to the end of its loop, then stop. The drive then exits
maintenance mode. The Fast Read/Write Test performs fewer tests than the Run
Tape Drive Diagnostics test (Function Code 1).
Attention:
For this test, insert only a scratch (blank) data cartridge or a
cartridge that may be overwritten. During the test, the drive overwrites the data
on the cartridge.
1.
Make sure that no cartridge is in the drive.
2.
Make sure that the following message appears on the message display (you
may need to turn the power off, then on again for the message to appear):
Ultrium Tape Drive
Drive Empty
3.
Within two seconds, press the unload button 3 times. The status light becomes
solid amber and the following message displays (indicating that the tape drive
is in maintenance mode):
Maint Mode: Select
Exit Maint Mode
Note:
If a cartridge is in the tape drive, it will eject the first time that you press
the unload button and the drive will not be placed in maintenance
mode. To continue placing the drive in maintenance mode, perform the
preceding step.
4.
Press the unload button once per second until
F
appears in the single-character
display and the following message displays. (If you cycle past the desired code,
press the unload button once per second until the code redisplays.)
