Tape drive shows no media. Inventory doesn't work.
After working perfectly for many months, Backup Exec 2012 shows no media in the tape drive. We have an IBM Ultrium-HH3 single drive device. I have rotated several tapes through it and they all show as no media. When I run an inventory three things happen: 1. the drive name changes to red on the All Storage tab. 2. the drive goes offline. I then have to right-click on the tape drive name to uncheck offline. 3. I get errors related to the inventory. The two inventory errors are: "Inventory Drive 00030 - The job failed with the following error: Physical Volume Library Drive or Robot paused, offline, or disabled." The second error is: "The drive hardware is offline. Please confirm that the drive hardware is powered on an properly cabled."
How can I get it to recognize the tapes again? I checked Device Manager and everything looks normal there. This was suggested in a Knowledgebase article.
