Typically, when a failure of main storage or a storage-protect key occurs and refetch of the failed data is unsuccessful, a machine check interruption identifies the failed storage or key to the program. System control programs use that information to effect recovery, and, during the remainder of the initial program load (IPL) interval, will avoid the use of the reported failing storage or protect key.
