I/O error when no tape in drive

Hi

I have been getting a series of I/O errors with TSM 6.1.2 and an IBM LTO5 drive.

I use lin_tape 2.5.

After doing some lin_tape debugging, I have found that the I/O errors occur whenever TSM tries to access the drive, and there is no tape in the drive.

The lin_tape error codes mean no medium found...

If I move a tape into the drive, TSM happily interacts with the drive - no I/O errors.

Has anyone come across something similar?

For interest, I attach the lin_tape log below...

Best regards!
