Before we implemented SCHENV control, we depended on SYSAFF to direct a job toward the member running a suitable Db2 subsystem. Then we had a couple of instances where the target Db2 abended and would not restart on the 'normal' LPAR, but would run a different LPAR. The task of directing a slew of batch jobs containing SYSAFF to another LPAR was laborious and time consuming. Or else IPL.
With SCHENV, we could issue a few WLM commands to disable resources on the broken LPAR and enable them on the other one. No change to automation, no change to JCL. And most all, no unscheduled IPL. However, SCHENV would not (early 2000s) override SYSAFF. If SYSAFF and SCHENV conflicted, a job would just hang. So part of the supporting SCHENV code was to nullify any SYSAFF if SCHENV was also specified. If that has changed, we never revisited the issue. . .

We keep the SCHED to because it points to the actual resource requirement adding documentation.
