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

Explanation

The enclosure has been replaced and communication with the other node canister (partner node) in the enclosure is not possible. The partner node could be missing, powered off, unable to boot, or an internode communication failure may 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 will still exist because the enclosure has no identity. If the error has changed, follow the service procedure for that error.
  2. If the partner has started and is showing a location error (probably this one), then the PCI link is probably broken. Since the enclosure midplane was recently replaced, this is likely the problem. Obtain a replacement enclosure midplane, and replace it. See Replacing a control enclosure midplane.
  3. If this action does not resolve the issue, contact IBM Support Center. They will work with you to ensure that the system state data is not lost while resolving the problem.
