Cause and Solution
Drive hardware problem.
Do not force a dump; one already exists.
The drive determined that a tape path or read/write error occurred. To prevent
damage to the drive or tape cartridge, the drive does not allow you to insert a
cartridge if the current cartridge was successfully ejected. Perform the following:
If possible, use ITDT to collect the existing drive dump (see Use the IBM Tape
1.
Diagnostic Tool (ITDT) to Retrieve a Drive Dump on page 362).
If you cannot use ITDT, use the BlueScale Retrieve Drive Dump utility (see Use
the BlueScale Retrieve Drive Dump Utility on page 363).
2. Reset the drive (see Resetting a Drive on page 354), then retry the operation
that produced the error.
3. If the problem persists, contact Spectra Logic Technical Support and send the
drive dump to them, if requested (see Contacting Spectra Logic on page 7).
Note: The error code clears when you reset or power cycle the drive or when
you place it in maintenance mode.
Drive or media error.
See Chapter 9 – Configuring and Using Media Lifecycle Management, beginning
on page 245 for information about using MLM to determine the health of the
cartridge. See Chapter 10 – Using Drive Lifecycle Management, beginning on
page 290 for information about using DLM to determine the health of the drive.
The drive determined that an error occurred, but it cannot isolate the cause.
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.
