Azure Update Manager - Maintenance Window/Schedule for reboot only

Question

Hi, is it possible to define Maintenance Window/Schedule for reboot only (having completed OS updates installation requiring server reboot - Arc-enabled server)? For example, I want servers to be rebooted at 2:00am on each 20th day of the month or given number of days after Patch Tuesday?

Hi @Bojan Zivkovic,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

Schedule recurring updates on a VM please follow the below process

You can schedule updates from the Overview or Machines pane on the Update Manager page or from the selected VM.

To schedule recurring updates on a single VM:

1. Sign in to the Azure portal.
2. On the Azure Update Manager | Overview page, select your subscription, and then select Schedule updates.
3. On the Create new maintenance configuration page, you can create a schedule for a single VM. Currently, VMs and maintenance configuration in the same subscription are supported.
4. On the Basics page, select Subscription, Resource Group, and all options in Instance details.
   • Select Maintenance scope as Guest (Azure VM, Azure Arc-enabled VMs/servers).
   • Select Add a schedule. In Add/Modify schedule, specify the schedule details, such as:
   • Start on
   • Maintenance window (in hours). The upper maintenance window is 3 hours 55 minutes.
   • Repeats (monthly, daily, or weekly)
   • Add end date
   • Schedule summary
   The hourly option isn't supported in the portal but can be used through the API.

Below MS document has step by step process on how to do it.
