Removing system information for node canisters with error code 550 or error code 578 using the service assistant

The system recovery procedure works only when all node canisters are in candidate status. Ensure that the service assistant displays all of the node canisters with the 550 error code. The 550 error code is the expected node error when more than half of the nodes in the system are missing or when the active quorum disk cannot be found. If the service assistant displays any node canisters with error codes 550 or 578 and all the recommended actions have been completed on these nodes, you must remove their system data.

Before performing this task, ensure that you have read the introductory information in the overall recover system procedure.

To remove system information from a node canister with an error 550 or 578, follow this procedure using the service assistant:

  1. Point your browser to the service IP address of one of the nodes, for example, https://node_service_ip_address/service/.
  2. Log on to the service assistant.
  3. Select Manage System.
  4. Click Remove System Data.
  5. Confirm that you want to remove the system data when prompted.
  6. Remove the system data for the other nodes that display a 550 or a 578 error.

    All nodes previously in this system must have a node status of Candidate and have no errors listed against them.

  7. Resolve any hardware errors until the error condition for all nodes in the system is None.
  8. Ensure that all nodes in the system display a status of candidate.
When all nodes display a status of candidate and all error conditions are None, you can run the recovery procedure.
