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.

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