Error Handling During An Orchestrated Upgrade¶
This section describes the errors you may encounter during an orchestrated upgrade and the steps you can use to troubleshoot the errors.
For a successful orchestrated upgrade, ensure the upgrade prerequisites, procedure, and postrequisites are met.
If a failure occurs, use the following general steps:
Allow the failed strategy to complete on its own.
Check the output using the dcmanager strategy-step list command for failures, if any.
Address the cause of the failure. For more information, see Failure During the Installation or Data Migration of N+1 Load on a Subcloud.
Retry the orchestrated upgrade. For more information, see Distributed Upgrade Orchestration Process Using the CLI.
Orchestrated upgrade can be retried for a group of failed subclouds that are still online using the upgrade-strategy create --group <group-id> command. Failed subclouds that are offline must be retried one at a time.
