XenCenter

Applying Automated Updates

January 19, 2021

Contributed by:

XenCenter allows you to apply automated updates that are needed to bring your servers up-to-date. You can apply these updates simultaneously to one or more pools. When you choose to apply automated updates, XenCenter applies the minimum set of updates that are required to bring the selected pool or the standalone server up-to-date. XenCenter minimizes the number of reboots required to bring the pool or the standalone server up-to-date. Where possible, XenCenter limits it to a single reboot at the end.

As a prerequisite, XenCenter requires internet access to fetch the required updates. If your XenCenter is behind a firewall, ensure that it has access to the updates.xensource.com domain and subdomains on the citrix.com domain through the firewall.

When you choose to apply automated updates, all the required updates get applied. Automated updates do apply any Cumulative Updates that are available for a host. If a new Current Release version is available as an update, automated updates do not apply this update. In this case, manually select to update to the new Current Release.

To view the list of required updates, perform the following steps:

Select the server from the Resources pane.
Navigate to the General tab.
Expand the Updates section. You can see:
- Applied - lists already applied updates.
- Required Updates - lists the set of updates required to bring the server up-to-date.
  
  Note:
  
  If there are no updates required, the Required Updates section is not displayed.
- Installed supplemental packs - lists supplemental packs that are installed on the server (if any).
  
  Note:
  
  If you select a pool instead of a server, the Updates section on the General tab lists the updates that are already applied as Fully applied.

If you would like to install specific updates to a pool or a managed server, see Applying updates to your managed servers.

Note:

Automated Updates are available for Citrix Hypervisor Premium Edition customers, or customers who have access to Citrix Hypervisor through their Citrix Virtual Apps and Desktops entitlement. For more information about licensing, see About Citrix Hypervisor Licensing.

The following section provides step-by-step instructions on how to apply automated updates using the Install Update wizard.

From the XenCenter menu, select Tools and then select Install Update.
Read the information displayed on the Before You Start page and then select Next.
Select Automated Updates. This option is visible only if XenCenter is connected to at least one licensed pool or a licensed standalone server.
Select Next.
Select one or more pools or standalone servers to update and select Next. Any server or pool that cannot be updated appears grayed out.
The Install Update wizard performs several update prechecks, including the free space check on the servers.

Follow the on-screen recommendations to resolve any prechecks that are failed. If you prefer XenCenter to automatically resolve all failed prechecks, select Resolve All.
When the prechecks have been resolved, select Next to continue.

The Install Update wizard automatically downloads and installs the recommended updates. The wizard also shows the overall progress of the update, displaying the major operations that XenCenter performs while updating each server in the pool.
Notes:
- The updates are uploaded to the default SR of the pool. If the default SR is not a shared SR or has insufficient space, XenCenter tries to upload the update to another shared SR with sufficient space. If none of the shared SRs have sufficient space, the update is uploaded to the local storage of the pool master.
- If the update process cannot complete for any reason, XenCenter halts the process. This halt allows you to fix the issue and resume the update process by clicking the Retry button.
When the updates have been applied, select Finish to close the Install Update wizard.
