High availability (also known as fault tolerance or failover) is a common architectural requirement based on Microsoft Cluster Server (MSCS) that focuses on ensuring business continuity in the event of an interruption of IT resource availability. The main objective of implementing a high availability solution is zero downtime for IT resources.
You can install connectors in a high availability environment. High availability support provides failover capabilities and a solution for applying maintenance while avoiding service management downtime. For more information about installing connectors to work in a high availability CA SOI environment, see the Implementation Guide.
To install connectors to operate with a high availability domain manager, you must follow the process described in How to Implement CA SOI in a MSCS Environment in the CA SOI Implementation Guide, with the following differences:
Note: This procedure does not apply for installing the CA Spectrum connector when CA Spectrum is installed with Primary and Secondary SpectroSERVERSs (Distributed SpectroSERVER environment).
Verify the status of all connectors and remove any connectors reporting to the real node.
