Running system recovery using the service assistant
You can use the service assistant to start recovery when all node canisters that were members of the system are online and have candidate status. For any nodes that display error code 550 or 578, ensure that all nodes in the system are visible and all the recommended actions are completed before placing them into candidate status. To place a node into candidate status, remove system information for that node canister. Do not run the recovery procedure on different node canisters in the same system.
Before you begin
Before you begin this procedure, read the recover system procedure introductory information; see Recover system procedure.
About this task
Run the recovery from any node canisters in the system; the node canisters must not have participated in any other system.
