Table 8. Codes for error conditions and informational messages for the IBM 200/400GB LTO-2 Tape
Drive (continued). The single-character display clears if you power-off the drive.
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, see "Resolving media-related problems" on page 55.
The error code clears when you remove the tape cartridge or place the drive in maintenance
mode.
8
For SCSI drive:
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. See "Fixing SCSI bus errors" on page 53. 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 LDI (RS-422) error. The tape drive determined that a failure occurred in the tape
drive hardware or in the LDI (RS-422) connection. Run the LDI or RS-422 wrap test (see Function
Code 7 in Table 5 on page 36):
v If the diagnostic fails, replace the tape drive.
v If the diagnostic runs successfully, the problem is with the enclosure or the cable to the
enclosure. Refer to your enclosure's documentation.
The error code clears when you place the drive in maintenance mode.
o, c, b, or h
No error or message assigned. There may be a problem with the single-character display. Turn the
power off, then on and determine whether all segments on the single-character display are lit. If
so, you may have a down-level version of both your enclosure's firmware and documentation (the
documentation may not describe all of the available error codes). Refer to the latest version of the
firmware or documentation.
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 tape 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 35.
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.
