Do some SYSPARMS like IDRCSIZE, IDRCUSEDx, IOMAXREX can improve FICON channel utilization?
Release : 12.5
Component : CA Disk Backup and Restore
The IDRCSIZE, IDRCUSEDx, IOMAXREX SYSPARMS don't have any impact in channel utilization.
IOCHNBLK and SYNCDEVS can improve performance, but IOCHNBLK not nearly as much as SYNCDEVS.
