Button for ten seconds. A drive dump will be created.
Error Code Cause and Action
7
A high probability of media error. The tape drive determined that an error occurred because of a
faulty tape cartridge. Try another tape cartridge. If the problem occurs with multiple tape
cartridges, use the following procedure:
Attention: When you run the Test Cartridge & Media diagnostic, data on the suspect tape is
overwritten. Use only a scratch data cartridge to run the test.
1. If possible, run the tape cartridge in a different tape drive. If the operation in the other unit
fails and
6
or
7
displays, replace the media. If the operation succeeds, run “Function Code E: Test Cartridge &
Media” on page 22.
v If the diagnostic fails, replace the media.
v If the diagnostic succeeds, clean the drive head (see “Cleaning the Drive Head” on page 14)
and run “Function Code 1: Run Drive Diagnostics” on page 16.
– If the drive diagnostic fails, replace the drive.
– If the drive diagnostic succeeds, perform the operation that produced the initial media
error.
The error code clears when you remove the tape cartridge or place the tape drive in maintenance
mode.
8
Tape drive or SCSI bus failure. The tape drive determined that a failure occurred in the tape
drive’s hardware or in the SCSI bus. The error code clears 10 seconds after the drive detected the
error or when you place the drive in maintenance mode.
9
Tape drive or RS-422 error. The tape drive determined that a failure occurred in the tape drive’s
hardware or in the RS-422 connection. Replace the tape drive. The error code clears 10 seconds
after the drive detected the error or when you place the tape drive in maintenance mode.
A
Tape drive hardware problem. The tape drive determined that a problem occurred which
degraded the operation of the tape drive, but it did not restrict continued use. If the problem
persists, replace the drive. The drive is usable, though the Single-character Display continues to
indicate an error and the Status Light flashes amber.
The error code may clear when you cycle power to the tape drive or place it in maintenance
mode.
b
No error or message is assigned. See error code
8
in this table.
C
The tape drive needs to be cleaned. Clean the tape drive. See “Cleaning the Drive Head” on page
14.
The error code clears when you clean the tape drive or place it in maintenance mode.
d
No error or message assigned. See error code
0
in this table.
The Unload Button is depressed. Verify that the button pushes freely.
