Cluster Client Configuration

DRLM (Disaster Recovery Linux Manager) supports the creation of clients with Virtual IP (VIP) for cluster configurations. This feature allows DRLM to manage and interact with multiple nodes in a cluster as if they were a single entity, simplifying the disaster recovery process for clustered environments.

To configure a client with VIP in DRLM, first add each node in the cluster as a separate client in DRLM. Then, create a new client with the VIP address and add the previously created clients as nodes to the new client.

To add the nodes to the VIP client, use the drlm modclient -c cluster-vip -a client_id.

:~# drlm modclient -c cluster-vip -a 100
:~# drlm modclient -c cluster-vip -a 101
:~# drlm modclient -c cluster-vip -a 102

:~# drlm listclient

This will enable DRLM to recognize the client as a cluster and handle it accordingly.
