My question is, how do i verify which tape that is finished. Also I wanted to verify which tape that is currently being used and to be used.

In all honesty the best place would be the GUI - throwing commands at a 'noob', as you describe yourself, would possibly be a little unfair (initially)!

"finished" - do you mean full, can no longer be written to until all images have expired?

• in GUI under Media & Device Management/Media/Robots/your_robot(s) any media with a Status of 'Full' or 'Full MPX' is a candidate to be ejected & taken offsite (following your actual business requirements). Any that are 'Active' or 'Active MPX' are potentially available to be written to. There are also 'Frozen' & 'Suspended' statuses which cannot be written to, but we'll leave them for now.

"currently being used" - do you mean actively being used at that moment, actually being written to?

• best place would probably be in the GUIs Activity Monitor/Drives tab

"to be used"

• any 'active' media that is in the library has the potential to be used next.

Your business requirements/procedures should be dictating what media is ejected from your library to go offsite & when - could be that even some 'active' media are also candidates for ejection - thus freeing up slots in your library.....
