When you scale OpenSearch by adding additional nodes in traditional storage, you must update the OpenSearch configuration.
To modify OpenSearch configuration:
Log in to the Sentinel server as the novell user.
Open the /etc/opt/novell/sentinel/config/opensearch-index.properties file.
Add the external OpenSearch nodes IP addresses to the property ServerList.
For example: ServerList=<opensearch IP1>:<Port>,<opensearch IP2>:<Port>
