1) For CHKPPRC - Automation Tools may only look for completion messages. Currently there are only 2 completion messages. IAS0070 40 A PPRC check for the IASP CRG &1 has failed. IAS0071 20 A PPRC check for IASP CRG &1 completed successfully
Automation software will miss Successfull CHKPPRC but with errors or warnings.
2) The existence of a stranded ESE Flash Copy could cause the Source Flash copy volumes to fill up and go write inhibited, causing an outage on the IBM I. This is an additional safety check to ensure no ESE Flash Copy relationships remain inadvertently.
