I have a program that accesses offline volumes to report on the volser. It 
works fine for both VM and MVS volumes, but occasionally, It takes a long time 
or doesn't return the volser.  I suspect  it is a dual copy volume being used 
for Volume Migration, with a PACE(0) set which does not allow ANY I/O's to the 
volume. For PPRC or other copies, PACE CANNOT be 0 therefore other I/O's can 
always get in. The volume I am looking at is the Primary in a Dual Copy Pair, 
but I can't determine the pace parameter being used.

Does anyone know what control block would have the Pace value?

When I look at The volume using ISMF, ISMF gets the volser with no trouble.

Thanks
Bill
