4. Troubleshooting Updates
Despite meticulous planning and execution, you may sometimes encounter issues during updates. When this occurs, Azure Stack Hub provides comprehensive troubleshooting capabilities.
For instance, you can opt to retry updating. However, before doing this, it’s recommended to check the update activity logs to identify the possible cause of the failure. Azure Stack Hub also provides detailed documentation on common update errors, which you can look up by match the error code obtained from your log.
In the event of persistent issues, you can also use the Microsoft Azure Stack Hub support and recovery tool to collect logs. This information can then be shared with Microsoft support to formulate a solution.
This guide provides an introduction to updating Azure Stack Hub, something considered fundamental knowledge for AZ-600 exam. By mastering the processes elaborated here, you will be well-positioned to conduct effective scheduling, deploying, monitoring, and troubleshooting of updates in a real-world hybrid cloud environment.
