This procedure describes how to patch a Platform Services Controller configured in a High Availability (HA) environment.
Platform Services Controller high availability deployments have at least two joined Platform Services Controller instances in a vCenter Single Sign-On domain. The Platform Services Controller instances use a third-party load balancer to ensure automatic failover without downtime in the event an instance becomes unavailable.
Using the load balancer, you must disable monitoring and node membership on the first Platform Services Controller instance (Node 1), and redirect all connecting clients to the second Platform Services Controller (Node 2). You can then patch Node 1. After successfully patching Node 1, redirect all connecting clients to Node 1 and patch Node 2.
- Verify that a backup of the Platform Services Controller appliances exist.
- Mount the upgrade .iso file to the virtual appliances.
- Ensure that you understand how to redirect the network traffic, and both enable and disable health monitoring on the load balancer in use in your environment. For more information, see vSphere Networking.
- Log in to vCenter Server using the vSphere Web Client.
- Direct traffic to Platform Services Controller Node 2, and disable health monitoring on the load balancer.
- In a Web browser, go to the Platform Services Controller virtual appliance management interface (VAMI) to configure the appliance system settings interface at
platform_services_controller_ip:5480.Log in as root. The default root password is the virtual appliance root password that you set when deploying the virtual appliance.
- In the vCenter Server Appliance Management Interface, click Update.
- In the Updates pane, click Check Updates and select Check CDROM.
- Validate that the loaded Available Updates match the appropriate version, and click Install Updates and select Install all updates.
- When the update finishes, click Summary to review the updates applied, and then click Reboot to cycle the appliance.
- After the reboot finishes, verify that the appropriate version number has been applied to the appliance.
- Re-enable traffic to the Platform Services Controller Node 1, and re-enable health monitoring on the load balancer.
You have applied a patch to first Platform Services Controller instance (Node 1), and re-enabled both network traffic and health monitoring on the load balancer for this node.
- Repeat this procedure on the second Platform Services Controller (Node 2).
What to do next
If multiple Platform Services Controller HA instances are available in your environment, repeat the preceding procedure for each instance until all Platform Services Controller HA instances have had patches applied.
