65F

Explanation
The system resources manager (SRM) stopped the
collection of channel measurement data in the channel measurement
block (CMB) because of an error condition.

System action
The system writes message IRA602I to identify
the error.  The system writes a logrec data set error record. The
system abnormally ends the current task. It cannot be resumed until
the next IPL.
The SRM functions, device selection and I/O balancing,
use algorithms that do not make use of CMB data.

System programmer response
Look at the reason code in message
IRA602I. Search problem reporting data bases for a fix for the problem.
If no fix exists, contact the IBM® Support
Center. Provide the logrec data set error record.
