Ted, And that's it? You didn't use DUAL mode? You didn't re-evaluate and adjust your Queue parms (Dormancy and Hold)? If you are not using a coupling facility for your checkpoint dataset, then I hope that you are using DUAL mode with or without Remote Copy.
If your device usage is already adding up to 100% across systems, without corresponding IO activity then it means that your checkpoint datasets are probably being accessed on contention basis. You will have to tune your Hold and Dormancy values to make your batch report systems are getting favoured access. When a job needs to go to the BLOB for more trackgroups it is going to wait until it gets control of the checkpoint. Remote Copy changes the basic dynamic of a "many member MAS" and you need to ensure that your loved ones are still getting their share.
