Issue/Introduction
Do some SYSPARMS like IDRCSIZE, IDRCUSEDx, IOMAXREX can improve FICON channel utilization?
Environment
Release : 12.5
Component : CA Disk Backup and Restore
Resolution
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.
