 The configured `tls-ca` secret is retrieved when Rancher starts. On a running Rancher installation the updated CA will take effect after new Rancher pods are started.
 
+The certificate chain must be properly formatted, or components may fail to download resources from the Rancher server.

 :::
 
+## Adding Additional CA Certificates
+
+If you are using a node driver that makes API requests with a different CA than the one configured for Rancher, you can add additional root certificates and certificate chains. 
+
+Create a unique file ending in `.pem` for each certificate that is required, and use kubectl to create the 
+`tls-additional` secret in the `cattle-system` namespace.

+- There is a [known issue](https://github.com/rancher/rancher/issues/25478) in which the Rancher UI doesn't show the state of etcd and controlplane as drained, even though they are being drained.
+- During an upgrade, nodes may be drained even when no user-visible YAML changes are present. This can occur if non-dynamic configuration files are updated or if a new `system-agent-installer` image is introduced. In such cases, Rancher generates a new upgrade plan, resulting in a new plan hash. When `Upgrade Strategy` is set to `Drain nodes`, this plan change can trigger node draining.
