Corrected answer 16 and added a bit to 17

16. difference between frozen and suspended media ?
     frozen -
     *Netbackup will freeze a tape if it shows an error, or we can freeze it manually.

Media should NEVER be frozen manually
    The media is NOT write protected, but NBU will not use it
    Frozen will not expire..
    

Suspended-
     *Netbackup will NOT auto suspend a tape. we have to suspend ourself.
     Suspended tapes will expire as normal and be available for re-use
 

   
17.what are the commands to check media info ?

nbemmcmd -listmedia is a better command the vmquery, so I would recommend this one as well as vmquery.
