Explanation
The system cannot reach a device through a path.
A hardware error occurred, or the data path switch for the device
is open.
In the message text:
- chp
- The identifier (CHPID) of the unavailable channel path.
- ss-cc-d
- The identifier of the storage director that found the problem.
System action
The system varies the path offline. If additional
paths are available, the system retries the failing channel program
on another path to the device.
Operator response
If the data path switch is open, close it.
Otherwise, do the following:
- Isolate the failing control unit. Contact hardware support to
repair it.
- If only one unit remains, transfer critical applications to back-up.
- Identify and recover failing tasks.
