Thanks for your reply, Rich. I also opened a ticket with IBM and received the response below. I used the STRDFU suggestion for the control groups with a few tape issues and wrote an SQL for the ones with a lot of tapes. It worked well and I cleaned up the inventory.
"Unfortunately it looks like something was done to create a lot of mismatches in your BRMS network. There are a couple of options to fix this, and the first one would be used typically when only a couple of tapes are this way. Only do this for volumes which are *EXP or have passed the *expiration date.
Option 1)
a. STRDFU <enter>
b. Update data using temporary program
Data file . . . . . . . . . qa1amm
Library . . . . . . . . . qusrbrm
c. Volume Serial Number: xxxxxx
d. change the System ID: to what you you want it to be so both systems see the same thing
e. F10
f. repeat for all volumes
Option 2)
a. Take apart BRMS network
b. Fix volumes so that they are owned by correct system
c. Put systems back into network"
