5.7.2 Operations Using a High Availability Cluster Configuration
This subsection describes how to start operations using a high availability cluster configuration, perform system switchover in the event of a failure at the executing node during operations, and recover the system.
After you finish configuring and setting up the environment, you can start system operations using a high availability cluster configuration. To start operations:
-
Check the status of the components of the executing and standby nodes.
To start operating the system with a high availability cluster configuration, the components of the executing and standby nodes must be in the status shown in the table below.

Connect the service requester network.
Connect the service requester network that was disconnected during setup.
When the service requester network is connected, service module execution requests can be accepted by the HCSC server at the executing node.
-
Service requester transmission control
Place the service requester in a status in which it can accept service module execution requests, such as by connecting the network for the service requester whose function for accepting service module execution requests was disabled during the setup.
