Explanation
An error has occurred on a PPRC primary device
when the controller is undergoing excessive recovery. This error would
normally be posted to the controller or the device as described in
the error-reasons.
In the message text:
- dev
- The device number of the primary device of a PPRC pair.
- error_reason
- The reason of the error, which is any of the following:
- PERMANENT I/O ERROR
- An error has occurred on a PPRC primary device. This error would
normally be posted permanent, but the device has been set to delay
the error posting to allow automation software analysis and possible
switch to the secondary device.
- EXCESSIVE CONTROL UNIT RECOVERY
- The controller is undergoing excessive recovery, and a HyperSwap® has been triggered.
The HyperSwap trigger
allows automation software to perform installation specific procedures,
such as to switch to use the secondary PPRC volumes. And there is
no need to shut down applications.
- HYPERSWAP NOT ACTIVE FOR DEVICE
- The controller is undergoing excessive recovery, and a HyperSwap has not been triggered
because it is inactive. Installation specific procedures should be
performed such as shutting down databases or shutting down noncritical
applications.
- PPRC PRIMARY FAILURE
- A write failure occurs during a write operation to the primary
device indicated by the volume serial number. A HyperSwap has also been triggered. The HyperSwap trigger allows automation
software to perform installation specific procedures to maintain data
availability. If HyperSwap was
not active, the message IEA491E is issued instead.
- volser
- This is the volume serial number of the PPRC volume.
- state
- The status of PPRC for Device dev
- ssid
- The ssid of the device in error.
- xx
- The two-byte channel connection address of the device.
- yyyy
- The device and channel status at time of permanent error.
- zz
- The IOSCOD (completion code) for the IOS request.
- optional-text
- CONTINUATION OF IEA497I SNS=sense
In the
message text:
- The sense data if present for the device error.
- sense
- The 32 characters of sense data reported by the device.
xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx
System action
If GDPS® is
active in the system, the combination of the HyperSwap trigger and the error-reasons
will fully allow automation software to perform installation specific
procedures to maintain data availability. If GDPS is not active, some other additional procedures
may have to be taken manually instead.
Operator response
This message is intended for automation software.
Any actions should be controlled by that software.
