509 The enclosure identity cannot be read.

Explanation

The canister was unable to read vital product data (VPD) from the enclosure. The canister requires this data to be able to initialize correctly.

User response

Follow troubleshooting procedures to fix the hardware:
  1. Check errors reported on the other node canister in this enclosure (the partner canister).
  2. If it is reporting the same error, follow the hardware remove and replace procedure to replace the enclosure midplane.
  3. If the partner canister is not reporting this error, follow the hardware remove and replace procedure to replace this canister.
Note: If a newly installed system has this error on both node canisters, the data that needs to be written to the enclosure will not be available on the canisters; contact IBM support for the WWNNs to use.
Remember: Review the lsservicenodes output for what the node is reporting.

Possible Cause—FRUs or other:

  • Node canister (50%)
  • Enclosure midplane (50%)
