Azure VM Reboots Without Installed Updates

Nana Poku 90

Azure update maintenance was scheduled to run over the weekend, and some of the servers rebooted without any updates being installed. What could be the cause of this issue?

Hi,

If the maintenance configuration was configured with Always reboot that will reboot the machines even if there are not updates. Other options if your Azure VMs (assuming they are and not Arc-servers) were set with property properties.osProfile.linuxConfiguration/windowsConfiguration.patchSettings.automaticByPlatformSettings.rebootSetting set to Always or IfRequired. That setting should not be configured when patchMode is set to AutomaticByPlatform and bypassPlatformSafetyChecksOnUserSchedule set to true as those settings designates that Guest patching should be used by the VMs and if configured it will not honor the reboot setting on the maintenance configuration.

Hi Stanislav,

Thanks for this as is very helpful but I have just seen on the activity logs there was ResourceOperationSubmissionFailed message on the Saturday the 14th.
