A word of caution here, I realize it appears the problem is resolved going from z/VM 4.4 and 5.3. However, I can not tell you any change that has been made to Diag X'254' nor RMS that would have magically allowed a target category of VOLSPECIFIC to be honored by the ATL on a mount command. I can tell you, hardware has identified situations where VOLSPECIFIC is not honored as a target category on a mount command. And I am not aware the fix has been released. Make sure you consider this carefully before going into production.
JR, didn't you make a change at one time where the set category was done separate from the mount? Could it be in one of the environments this code was being executed?
