Explanation
The system resources manager (SRM) stopped the
collection of channel measurement data in the channel measurement
block (CMB) because of an error condition.
In the message text:
- reason-code
- The reason code in hexadecimal, as follows:
- 01
- Time of day (TOD) clocks are out of synchronization.
- 02
- Channel timers are out of synchronization.
- 03
- A storage check occurred on channel access to CMB.
- 04
- An uncorrectable program error occurred while SRM was processing
measurement data.
- 20
- There is not enough virtual storage for the required measurement
data areas.
- 21
- A unit control block (UCB) contained a zero measurement block
index. block (UCB)
- 22
- A protection or addressing exception occurred on channel access
to the CMB.
System action
The SRM functions, device selection and I/O load
balancing, use algorithms that do not make use of CMB data. If device
connection times were being collected, the system writes message IRA601I.
The system abnormally ends the current task with abend code X'65F'.
System programmer response
See the system programmer response
for abend code X'65F'.
