070
Explanation
During initial program load (IPL) processing, IPL did not find enough contiguous central storage to satisfy a request that requires contiguous storage. This is probably a hardware error.
Operator response
Check the configuration of storage. If hardware errors have made too many frames unusable, contact hardware support. Otherwise, notify the system programmer.
System programmer response
Make sure that enough central storage is available for IPL processing. You may have to reduce the number of optional system facilities selected for this system configuration.
