502 No enclosure identity exists and a status from the partner node could not be obtained.

Explanation

The enclosure was replaced and communication with the other node canister (partner node) in the enclosure is not possible. The partner node might be missing, powered off, unable to boot, or an internode communication failure might exist.

User response

Follow troubleshooting procedures to configure the enclosure:
  1. Follow the procedures to resolve a problem to get the partner node started. An error still exists because the enclosure has no identity. If the error changes, follow the service procedure for that error.
  2. If the partner node starts and is showing a location error (probably this error), then the PCI link is probably broken. Because the enclosure midplane was recently replaced, the enclosure midplane is likely the problem. Obtain a replacement enclosure midplane, and replace it.
  3. If this action does not resolve the issue, contact IBM® Support Center. They work with you to ensure that the system state data is not lost while you resolve the problem.

Possible Cause—FRUs or other:

  • Enclosure midplane (100%)
