I already have the list of backups and I can create a million+ line JCL but would prefer not to. It would be best if HSM would simply delete the backups that are no longer valid once I change the Management class definition. I don't know about you, but that seems quite reasonable to me.
However, this is not the case. Removing the backup requirement from the Management class definition, I am still left with all the backups even after HSM Space Management and a run of EXPIREBV. Is there really no better solution to this? David G.

Using ISPF 3.4 and saving the list would work. May have to do that in batch also if some pattern can be used to match millions at once (to possibly increase allocation amounts). Running this would be quicker than ISPF 3.4 (modify "L" or pass the parm as needed for HLQ / pattern) PROC 0 L(&SYSUID) G(SAVE) /* */ /* Quick ISPF save of data set names.
