501 Incorrect slot

Explanation

The node canister has saved cluster information, which indicates that the canister is not located in the expected enclosure, but in a different slot from where it was previously used. Using the node canister in this state might mean that hosts are not able to connect correctly.

User response

Follow troubleshooting procedures to relocate the node canister to the correct location.
  1. Follow the Procedure: Getting node canister and system information using the service assistant task to review the node canister saved location information and the status of the other node canister in the enclosure (the partner canister). If the node canister has been inadvertently swapped, the other node canister will have the same error.
  2. If the canisters have been swapped, use the Replacing a node canister procedure to swap the canisters. The system should start.
  3. If the partner canister is in candidate state, use the hardware remove and replace canister procedure to swap the canisters. The system should start.
  4. If the partner canister is in active state, it is running the cluster on this enclosure and has replaced the original use of this canister. Follow the Procedure: Removing system data from a node canister task to remove cluster data from this node canister. The node canister will then become active in the cluster in its current slot.
  5. If the partner canister is in service state, review its node error to determine the correct action. Generally, you will fix the errors reported on the partner node in priority order, and review the situation again after each change. If you have to replace the partner canister with a new one, you should move this canister back to the correct location at the same time.
