Tape Drives - (no Media)

When the be15 services start my tape drives show a tape inside of them (see pic 1)

Then a few mins later all of the drives go to status (No Media) from there any backups to tape just queue forever. Any backups to disk flow through just fine and complete. 

I have rebooted and resyned the server and drives. i have done my updates to BE. Rescanned the Drives, Inventory Slots, cleaned the drives. The Actual Robotic library doesnt show any issues on Drive 2-4. 

Errros in the ADAMM.log show the following when i attempted to do a backup and it was queued.

I was thinking about removing the drivers from windows, rebooting letting it reinstall. what is everyone elses thoughts?

  • I would suggest that you run the manufacturer's tape diagnostics first.  Stop all BE services before doing so.

  • When the BE services start, they will unload any occupied robotic tape drives and return the tape cartridge to an empty storage slot.  This is done as an error recovery process because the tape drives should be empty when BE services start cleanly.  Basically, unless you crash BE or crash the server, BE always unloads tape drives when it is done with an operation.
