We upgraded to ZOS 1.7 this weekend and had an issue with Compaktor. We
started getting U888 abends and found out our FDR was backlevel. The real
question is: Is there a need to run Compaktor on ML1 volumes? It seemed to
have scrambled some HSM VVDS entries....TIA.
Daniel, I am sorry you got bit by that problem. V5.4/50 of COMPAKTOR is
required for z/OS 1.7 and up because of changes in UCBs and VSAM control
blocks. Actualy V5.4/50 is the required level of all FDR products for 1.7
You can see the chart of minimum levels and the current level of each
FDR product at

As far as COMPAKTing ML1 volumes, it depends on the free space on the
volumes. Lots of free space doesn't require COMPAKTion, but if it is
tight on space COMPAKTOR can help improve it. You can specify parms to
COMPAKTOR so that it will bypass volumes that are not short of space.
