The first one is "robtest". This program is usually located in the c:\program files\netbackup\volmgr\bin folder and allows you to check various functionality of an attached tape library.
Here are some examples that you would type at the command line:
The above command should list the status of the tape drives with items such as tape number loaded in the drive.
The above command should show you the status of the tape library slots. Beware that if you have a large tape library the results may show on more than one screen.
m s1 d1
The above command should move a tape loaded in Slot 1 to Drive 1. For each of the numbers you can adjust for the slot and drive number accordingly.
The above command should unload a tape in Drive1 and prepare it for movement back to a slot or removal.
m d1 s1
The above command should move the unloaded tape from Drive 1 and put it back in Slot 1
I will try to add others as soon as I have time to put a few words together about each.
Please feel free to post your own.
