IEA447E
PATH chp TO DEVICE s-cc-d UNAVAILABLE

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.
