About DFSMSrmm CDS utilization
bjbxd
I found the DFSMSrmm CDS utilization is 88% from TSO RMM LC command,
but, from the LISTCAT output of CDS Dataset, the utilization is 79%:
HI-U-RBA/HI-A-RBA = 3365007360/4220436480 = 0.797 = 79.7%
Would you pls help to explan the difference between these 2 points.
Here is the listcat output of DFSMSrmm CDS Dataset:
