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:

  1. Allow the failed strategy to complete on its own.
  2. Check the output using the dcmanager strategy-step list command for failures, if any.
  3. Address the cause of the failure. For more information, see failure-during-the-installation-or-data-migration-of-n-plus-1-load-on-a-subcloud.
  4. Retry the orchestrated upgrade. For more information, see Distributed Upgrade Orchestration Process Using the CLI <distributed-upgrade-orchestration-process-using-the-cli>.

Note

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.
