This is the Error Condition Signal. HP StorageWorks DAT drives
perform a comprehensive self-test during power-up. If a hard
error causes the self-test to fail, the clean light changes to
steady amber. Run HP Library & Tape Tools to help diagnose
the problem.

This is the Media Caution Signal.
1. Wait for the current operation to finish, then insert a
different tape and repeat the operation that was being
performed.
2. If the media caution signal does not show this time, it
indicates that the original cartridge was nearing the end
of its useful life. Copy any data you want to keep from the
original tape onto a new tape if possible, then discard
the old tape.
3. If the media caution signal appears again with the second
tape, the tape heads need cleaning.
4. If the media caution signal appears after using a cleaning
cartridge, the cleaning cartridge has probably expired and
should be discarded.

When the two LEDs flash alternately, the tape drive is in
disaster recovery mode, restoring the operating system (see
“ Running HP OBDR ” on page 52).
