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.
Prerequisites
- 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.
Procedure
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.
