You can activate continuous availability (CA) for VMware Aria Operations to protect your data if there is one or more node failures.
Note: If the cluster is running, activating CA restarts the cluster.
You can activate CA in the VMware Aria Operations cluster at the installation time or after VMware Aria Operations is up and running. Adding CA at installation is less intrusive because the cluster has not yet started.
Prerequisites
- Create nodes by deploying the VMware Aria Operations vApp.
- Create and configure the primary node.
- Create and configure the witness node.
Note: VMware Aria Operations can have only one witness node in its cluster. While deploying an OVA file, you can select the recommended CPU/RAM configuration for the witness node.
- Create and configure one data node with a static IP address.
- Note the fully qualified domain name (FQDN) or IP address of the primary node.
