Restarting a Local Processor
You must restart a local processor after an MVS™ failure or a JES3 failure on the local processor. You must restart all local processors after performing a cold start or any type of warm start on the global processor.
After an MVS failure on a local processor, perform an MVS IPL and then a local start. After a JES3 failure, you need not perform the IPL, just the local start.
After an IPL on a local processor, JES3 processes jobs that were previously running on the local processor according to their failure options.
If JES3 cannot be restarted on a local processor, logically remove the processor from the complex. To do this, the operator must enter the command *S,main,FLUSH.
