How the USEDSSIO parameter should be coded for the volcount greater than 20 ?
Release : 12.5
Component : CA Disk Backup and Restore
APAR #: RO18279 introduces the enhancement providing native I/O support for data sets existing on more than twenty volumes in the following functions: Archive, Backup, Restore, and Recovery
This removes the need to use the DFSMSdss data mover for these data sets.
Coding USEDSSIOMAXVOLS is no more needed.
