The time that we received these errors was on a ADIC Scalar 10K. After trying
to get both ADIC and Symantec to work on the problem, ADIC finally came back
and said the library is misconfigured. The option we ended up changing was
"eject drive on move command". It was set to "software issues eject". Basically
the drive occasionally didn't receive the eject command from the software and
there was no retry. Now the library will issue an eject if the tape is still in
the drive when asked to move the tape. It's worked fine ever since.
