After you start Instant Messaging, you need to verify the HA configuration as described in this section.
Check that all required processes are running.
Conduct a switchover of the service to the backup node to ensure the high availability.
For example, if the service is running on im_node_1, issue the following command to switch the service to im_node_2.
# scswitch -z -g im_resource_group -h im_node_2 |
Check that all required processes are started on im_node_2 .
