Manage update settings for Azure Local

This article provides an overview of different Azure Local update settings that control how updates are applied. The default settings provide a balanced experience of update run time versus potential workload impact. Use the available controls to fine tune and optimize the update behavior to your servicing requirements.

Prioritization

When updating Azure Local, the process live migrates virtual machines between cluster member machines to ensure workloads don't experience any downtime. Live migration failures are rare but can happen, for example, due to VM misconfigurations like attaching a virtual image (ISO) stored on a local storage path instead of a shared location (CSV).

The default solution setting prioritizes completing the update over workload availability when live migrations fail.

By using the following steps, you can change this behavior so that when live migrations fail, the update process aborts.

# Prioritize workload uptime over update completion
Enable-UpdateSetting -Name SkipForceDrain

To confirm if the setting is enabled, run this command:

# Confirm setting status
Get-UpdateSetting -Name SkipForceDrain

To switch back to the default behavior, run the following command:

# Rollback to default behavior
Disable-UpdateSetting  -Name SkipForceDrain

To confirm the feature is disabled, run the following command:

# Confirm setting status
Get-UpdateSetting -Name SkipForceDrain
