Cause and Solution
High probability of media error. An error occurred because of a faulty tape
cartridge.
 Ensure the tape cartridge is the correct media type:
 See LTO Read/Write Compatibility on page 494 for information about which
media is compatible with each LTO drive generation.
 Drive does not accept an expired cleaning cartridge.
 Drive does not accept a WORM cartridge when running diagnostic tests in
Maintenance Mode.
 Drive does not write over existing data sets on a WORM cartridge. Ensure
you are appending data sets on WORM media rather than attempting to
write over existing data sets.
 If another drive is available, insert the cartridge into the other drive and retry
the operation.
 If the operation fails, discard the defective cartridge.
 If the operation succeeds, use the Drive Health Verification wizard to test
the original drive (see Using DLM to Test a Drive on page 382).
 If the drive fails the DLM drive test, contact Spectra Logic Technical Support
(see Contacting Spectra Logic on page 7).
 If the diagnostics succeed, the error was temporary.
 If another drive is not available, use the Drive Health Verification wizard to
test the drive.
 If the drive fails the DLM drive test, contact Spectra Logic Technical Support.
 If the drive passes the DLM drive test, retry the operation to determine whether
the error was temporary. If the operation fails again, discard the cartridge.
Note: The error code clears when you reset or power cycle the drive or when
you place it in maintenance mode.
SCSI interface or Fibre Channel failure.
A failure occurred in the drive hardware or in the SCSI bus. The error code clears
after 10 seconds if the error does not recur. If the error persists, contact Spectra
Logic Technical Support (see Contacting Spectra Logic on page 7).
RS‐422 error.
The drive determined that a drive interface or library interface failure occurred.
The error code clears after 10 seconds if the error does not recur. If the error
persists, contact Spectra Logic Technical Support (see Contacting Spectra Logic
on page 7).
