accessing RSM information from powershell or command line

I am trying to get information on Tape Mount Counts to determine when tapes are nearing their life expectancy.

I have been unable to find a way to access the information without using the Management GUI and doing a lot of clicking.

I would prefer to query the system to find out what tapes are in the library, and what their mount counts are.

Using Powershell and RSM View, I can enumerate all the tapes, their labels and guids, but I can't find a way to get the mount count.

Can someone point me in the right direction?

thanks,

Ole Jensen.
