Has this problem been seen at an OST version higher than 2.2.1.1? We are seeing skewed numbers at version 2.2.2.0, we are not getting the error 129 because HWM is already at 99%
You can use the standard binaries to install NetBackup in a virtual environment. The following 2 documents detail NetBackup's support in a virtual environment:
NBU 6.x: http://seer.entsupport.symantec.com/docs/312604.htm
NBU 7.0: http://seer.entsup...
I think the easiest way to do this would be to re-install NetBackup on that media server and choose the master server option. Once you have the software installed, configure your robots/drives, and perform a catalog restore
