Which backup device did you have, and what do you have now? Is Library and Tape Tools able to detect and operate the drive? If you're on Windows, is it able to see the drive in device manager and operate the drive using NTbackup?

However the new drive appears as offline and initializing the library does not work.<BR /> <BR /> It appears to me as if the license is still attached to the old drive.....how can I release the license back to to license pool?<BR /> <BR /> <BR /> <BR /> thanks <BR /> <BR /> jorge Mon, 15 Mar 2010 12:32:18 GMT https://community.hpe.com/t5/automated-backup/error-131-instance-is-not-licensed/m-p/1142602#M1144 jorgelopez 2010-03-15T12:32:18Z https://community.hpe.com/t5/automated-backup/error-131-instance-is-not-licensed/m-p/1142603#M1145 It might help to know a bit about your environment.
