Dell PowerVault 110T LTO2 (Tape Drive) - Manual (Page 21)

To view the drive error log:
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval press the eject button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.
3. Press the eject button once per 1.5 seconds until 9 appears in the single-character display.
4. Press and hold the eject button for 3 seconds to view the most recent error code.
5. Refer to Descriptions and Corrective Actions to determine the meaning of the code and the action to take.
6. Press the eject button to view the next error code. (The codes are ordered; the most recent is presented first and the oldest (tenth) is presented last.)
7. Continue to press the eject button until "0" appears, indicating that no more error codes exist. If no errors have been encountered or the log has just been cleared, a
"0" will appear immediately and the drive will exit maintenance mode. A maximum of ten error codes are stored.
To redisplay the error codes, repeat steps 1 through 7.
Function Code A - Clear Error Code Log
Causes the tape drive to erase the contents of the error code log.
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the eject button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.
3. Press the eject button once per 1.5 seconds until A appears in the single-character display. If you cycle past A, continue to press the eject button until it
redisplays.
4. To select the function, press and hold the eject button for 3 seconds. After you select the function, the tape drive erases all errors from the error code log, displays
0, then exits maintenance mode.
Function Code C - Insert Cartridge into Tape Drive
This function cannot be selected by itself. It relates to other maintenance functions (such as Run Tape Drive Diagnostics) that require a scratch tape cartridge that is not
write protected.
Function Code E - Test Cartridge & Media
Causes the tape drive to perform a Write/Read test (on the edge bands) to ensure that a suspect cartridge and its magnetic tape are acceptable. The tape drive takes
approximately 10 minutes to run the test.
Attention: Data on the suspect tape will be overwritten.
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the eject button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.
3. Press the eject button once per 1.5 seconds until E appears in the single-character display. If you cycle past E, continue to press the eject button until it redisplays.
4. To select the function, press and hold the eject button for 3 seconds. After you select the function, C flashes. When C flashes, the drive is waiting for a cartridge.
Within 60 seconds, insert the suspect data cartridge (or the tape drive exits maintenance mode). After you insert the cartridge, E flashes and the test begins:
¡ If no error is detected, the test begins again and runs for a maximum of 10 times. After the tenth loop, the test stops and the drive automatically exits
maintenance mode. To halt the test, press the eject button. The drive acknowledges the request by slowing the length of time that the currently displayed
character flashes on the single-character display (from twice per second to once per second). The test continues to the end of its loop and then stops. The
tape drive then rewinds and unloads the cartridge, displays 0, and exits maintenance mode.
¡ If an error is detected, the tape drive displays 7, unloads the tape cartridge, and exits maintenance mode.
Function Code F - Fast Read/Write Test
Causes the tape drive to perform tests to ensure that the drive can read from and write to tape. This diagnostic performs fewer tests than the Run Tape Drive Diagnostics
test (Function Code 1). The tape drive takes approximately three minutes to run the test. The Fast Read/Write Test is not as comprehensive a test and is not
recommended for isolating errors between the drive and the media.
Attention: Data on the suspect tape will be overwritten.
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the eject button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.
3. Press the eject button once per 1.5 seconds until F appears in the single-character display. If you cycle past F, continue to press the eject button until it redisplays.
4. To select the function, press and hold the eject button for 3 seconds. After you select the function, C flashes. When C flashes, the drive is waiting for a cartridge.
Within 60 seconds, insert the suspect data cartridge (or the tape drive exits maintenance mode). After you insert the cartridge, F flashes and the test begins.
¡ If no error is detected, the test begins again and runs for a maximum of 10 times. Each loop takes approximately 3 minutes to run. After the tenth loop, the
test stops and the drive automatically exits maintenance mode. To halt the test, press the eject button. The drive acknowledges the request by slowing the
length of time that the currently displayed character flashes on the single-character display (from twice per second to once per second). The test continues to
the end of its loop and then stops. The tape drive then rewinds and unloads the cartridge, displays 0, and exits maintenance mode.
¡ If an error is detected, the tape drive displays an error code, unloads the tape cartridge, and exits maintenance mode.
Function Code H - Test Head
Causes the tape drive to perform the Head Resistance Measurements test and a Write/Read test (on the center of the tape). The drive runs these tests to ensure that the
tape drive's head and tape-carriage mechanics are working correctly. The tape drive takes approximately 10 minutes to run the test.
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the eject button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.
