Why won't my software communicate with the tape library, and why am I getting SCSI sense errors KEY = 02 ASC = 04 ASCQ = 8E?

Version 1

    Cause: If your backup software is not communicating with the tape library and you are getting SCSI sense errors KEY = 02 ASC = 04 ASCQ = 8E, it might be because the library is in Sequential mode instead of Random mode. Most software manufacturers require the tape library to be in Random mode.

    Solution: Check with the manufacturer of your backup software to verify the best mode of operation. If applicable, change the mode to Random.
