(APAR IC84037) - Metro Global Mirror will not start after a HyperSwap command
After performing a HyperSwap in a z/OS Metro Global Mirror session, the session is unable to start. Tivoli Storage Productivity Center for Replication fails with IWNR2108E and an error code of 0400. To avoid this issue, it is suggested that customers do not install PTF UK78825 and instead apply PTF UK79737, which contains a fix for APAR IC84037.
This issue applies only to customers who have enabled HyperSwap on z/OS in a Metro Global Mirror session.
