In order to speed up jukebox operations, NetWorker maintains a cache, or a map, if you will, of the current expected jukebox state based on the operations that have happened since it was last fully queried. This avoids having to do (time) costly SCSI probes before every operation.
(This, for what it’s worth, is why you [...]

Getting around this behaviour is [...]
Having a strong support background, and having a preference for working in software rather than hardware, when I use NetWorker’s nsrjb utility with tape libraries I like to get as much feedback as possible on operations.
When performing command line operations with nsrjb, this is relatively straight forward – just add on a few “-v” options [...]
