Our environment is Netbackup 5.1 MP3 HP-UX 11.31 (11i v3).   I just removed our media server and am using the master as the media server.  I ran a script that did bpmedialist and bpmedia –movedb commands to move my media from the media server to the master server.  I have changed my bp.conf and vm.conf files so they no longer have anything from the old media server.  I used tpconfig to remove the robot and drives from the old media server.  Connected the drives to the master server and can see them via an ioscan.  I used the NBU gui to add the robot and drives to the master server.  I can see everything on the master server but when I kick off a job I'm getting "EXIT STATUS: 219 - the required storage unit is unavailable" .  I tried to run an inventory and am getting "robot number and robot host mismatch".  I found a document that says to select all the tapes in the library, click on Actions -> Move and uncheck the Volume is in a robotic library box and click OK.  There are about 300 tapes in the library, I did this and it's been sitting there for quite a while.
