CLI Script: Manual detailed inventory of unknown tapes

The following script runs detailed inventory on all unknown tapes in all the libraries attached to the specified DPM server. Save this script as a .ps1 file and run it. Usage and examples of scripts can be found by calling them with ‘-?’ or ‘-help’ from inside DPM Management Shell.

This is for manually running the detailed inventory job. Btw, for running the inventory on a regular scheduled basis, then use Get/Set-MaintenanceJobStartTime and DPM will automatically run the inventory at the specified time.
