Cause and Solution
Drive or media error.
See Chapter 9 – Configuring and Using Media Lifecycle Management, beginning
on page 284 for information about using MLM to determine the health of the
cartridge. See Chapter 10 – Using Drive Lifecycle Management, beginning on
page 330 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 550 for information about which
media is compatible with each LTO drive generation.
 Drive will not accept an expired cleaning cartridge.
 Drive will not accept a WORM cartridge when running diagnostic tests in
Maintenance Mode.
 Drive will 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.
Confirm that the cartridge is the correct media type. If it is, determine whether
the problem is associated with writing or reading data to a single cartridge or
multiple cartridges.
Problems Writing Data on a Cartridge with a Known Volume Serial Number
Retry the operation with a different cartridge.
 If the operation succeeds, the original cartridge was defective. If possible, copy
data from the defective cartridge and set the original cartridge aside. If
additional tests confirm that the cartridge was the source of the error, you can
discard it.
 If the operation fails and another drive is available, insert the original
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 430).
 If the drive fails the DLM drive test, contact Spectra Logic Technical Support
(see Contacting Spectra Logic on page 7).
 If the drive passes the DLM drive test, the error was temporary.
 If the operation fails and 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.
