You're point is valid, but I guess my concern was that it could accidentally happen because someone forgets to exclude them from the specified slot range. I just find it odd that NetWorker would actually work with those slots via the GUI but not
the CLI. I wonder if this is some kind of bug.

My experience in the past was that once a slot was set for cleaning, inventorying the slot effected no action.

I just realized that the cause of the problem is that 'Bar code reader' was set to 'No' and not 'Yes'. I changed it to 'Yes' and now NetWorker doesn't inventory those slots when performing an inventory from the GUI. Also checked again from the CLI via nsrjb and ditto, not that I would have expected nsrjb to do anything since it wasn't before. Now, according to the help page for the jukebox window under nwadmin, it shows the following for Default Cleanings:

Default Cleanings - Displays the number of times a new cleaning
cartridge added to a jukebox can be used. A cleaning cartridge is
considered new if, during the inventory of a jukebox, a slot set
aside for cleaning cartridges is now occupied, whereas before the
slot was empty. Volumes from slots set aside for cleaning
cartridges are not loaded during an inventory of a jukebox.
Therefore, a jukebox must support element status or a bar code
reader to determine the state of a slot set aside for cleaning
cartridges during inventory. This field can only be set for
jukeboxes that contain tape devices.

Perhaps, when doing things from the GUI, NetWorker could not determine the state of the slot set aside for cleaning without the bar code reader on, but it could do this from the CLI? Who knows. Anyway, I really have to have 'Bar code reader' turned off, though, because we don't have any custom bar codes yet, only generic ones which I keep reusing to make operations on the library faster. It's slow without them. I'll switch once we have them. I guess I just need to be careful not to inventory those slots from the GUI if 'Bar code reader' is set to 'No'.

George;

What's the point of inventorying cleaning slots? That makes no sense to do either via the GUI or CLI. My solution to your inventory problem is simple; don't bother. Or am I missing something?
