CHECK(IBMIOS,IOS_CMRTIME_MONITOR) determined that one or more control units had inconsistent command response (CMR) time. Each of these control units had at least one channel path with an average CMR time that exceeded the THRESHOLD parameter value and that path was significantly higher (as defined by the RATIO parameter value) than the path with the lowest average CMR time for this control unit. That is, the average CMR time for this path was at least 'x' times the lowest average CMR time for this control unit (where 'x' is the RATIO value).
This may happen when there is a problem somewhere in the fabric, such as, hardware errors, I/O mis-configurations, or congestion.
The system continues processing.
Contact the System Programmer.
Refer to the corresponding reports for this Health Check to determine which control units and channel paths have delays. Use diagnostic tools (such as the Resource Monitoring Facility (RMF™) or hardware diagnostics) to help determine the source of the problem.
