START PROCESSORS STOPPED FOR MESSAGE {IOS062E | IOS063E}—
RESERVES {INTACT | LOST}
Explanation
The system recovered from the error that appeared
in message IOS063E, (or IOS062E) which told the operator to stop the
processors that share devices with this system. The system issues
this message when channel path recovery is complete.
This message
is only issued when the asynchronous WTO request to issue IOS204E
has failed.
In the message text:
- RESERVES INTACT
- Indicates that all reserved devices were successfully recovered
- RESERVES LOST
- Indicates that one or more devices reserved for this system were
forced offline
System action
The system has completed channel path recovery.
When
the operator replies to message IOS201E, the system might issue one
or more additional messages either to indicate which devices are no
longer reserved to this system or to indicate which channel paths
were successfully recovered.
In addition, the system may abend
the jobs using boxed devices.
Operator response
Do the following:
- Isolate the failing channel path for repair.
- Identify and recover failing tasks.
- If RESERVES INTACT appears in the message text, do the following:
- Enter the IOACTION RESUME command for the device on all other
sharing systems if the device was stopped, or restart any stopped
systems, or vary the device back online. Start the stopped processors
by pressing the START key at the system console of each sharing system
or logical partition.
- Restart the system that detected the stopped processor.
- If RESERVES LOST appears in the message text, do the following:
- Enter the IOACTION RESUME command for the device on all other
sharing systems if the device was stopped, or restart any stopped
systems, or vary the device back online. Start the stopped processor
by pressing the START key at the system console of each sharing system
or logical partition.
- Restart the system that detected the stopped processor.
- Notify the system programmer.
When this message is issued before the MVS™ Console becomes active, IT IS EXTREMELY IMPORTANT
to respond promptly. This message is issued as a synchronous WTOR
during early IPL processing, which will prevent the system from updating
its status on the sysplex couple data set. This, in turn, could lead
to Sysplex Failure Management (SFM) deciding that the system is not
responding normally, and removing it from the sysplex.
