Description (partial)

The customer will see occasional IFCCs on the mainframe console which will be IOS050 or IOS051 messages for the XRC device acting as the reader for a particular XRC session. These should be retried by the mainframe IO subsystem and not cause a serious issue. In some cases this can cause XRC volumes to suspended.

This happens when the disk array sends a unit check to the system data mover.
