I updated using Live Update. Rebooted. Under Devices it had the library offline. Changed that back to online and then i get messages that the library is not found. I've diabled and enabled the device. Nothing works.

I also get this when i try to inventory now....

Inventory Library 00048 -- The job failed with the following error: Physical Volume Library Drive or Robot paused, offline, or disabled.

It is not paused.....offline....or disabled....????????????

TIA!

Check in device manager and make sure that the tape library is listed in device manager.  It should be listed under Medium Changers.  Also verify that the tape drives are still listed as well.

If both are listed, check the application/system event logs for any hardware errors.
