Adding Client Nodes to an Active SSR Cluster (SRC CLI)
This procedure makes the following assumptions:
You are working with an active cluster and the SSR database is in production mode. If you are unsure what mode the database is in, see Viewing the SSR Database Mode (SRC CLI).
You have physically installed the new C Series Controllers that will be acting as a client node, made the interface connections to the cluster, and installed the SRC software.
This procedure requires you to restart the management servers in the cluster, which is a disruptive process. This procedure should be performed only during a maintenance window. Review this procedure in full before proceeding.
To add a client node to an active cluster:
Configure the C Series Controller as a client node.
(Optional) Configure the new client node to host a management server.
Commit the configuration.
Place the database into maintenance mode.
Disable the component database on each management server in the cluster (one by one).
Enable the component database on each management server in the cluster (one by one).
(Optional) If the new client node is hosting a management server, you need to restart the component database and all SSR client components on all client nodes in the cluster (one by one). If the new client node is not hosting a management server, this step is not necessary.
Enable the component database on the new client node. If you have added more than one client node, perform this step on each new client node (one by one).
Verify the cluster configuration changes by viewing the status of the database.
Place the database into production mode.
