We are going to be replacing our 9940A tape drives with 9940B tape 
drives, and I will want to suspend all of the tapes that are currently 
assigned to the media servers.  This is to prevent NBU from attempting 
to use a tape written by the older drives in the new drives when doing a 
backup.  The "B" drives can read tapes written by the "A" drives but 
cannot append to them (as would be the case when doing a backup on a 
partially used tape).

My experience shows that if a partially used "A" tape is used in a "B" 
drive for a backup, NBU will find the tape "read only" and spit it out 
and try another tape.  I want to avoid this tape search by suspending 
all of our currently assigned tapes until the backups on those tapes 
expire naturally.

How do I find a list of assigned tapes and the media servers they are 
assigned to?  I'd like to write a single script that I run on the master 
server to do all the tapes if possible.  I know I can use vmquery to 
find out if a tape is assigned, but how, then, do you determine which 
media server owns the tape so I can give bpexpdate all the information 
it needs to suspend the tape?
