Sun Cluster 3.1 Data Service for DHCP

How to Verify the Sun Cluster HA for DHCP Installation and Configuration

Use this procedure to verify that you installed and configured Sun Cluster HA for DHCP correctly.

  1. Become superuser on one of the nodes in the cluster that will host DHCP.

  2. Ensure all the DHCP resources are online with scstat.

    # scstat 

    For each DHCP resource that is not online, use the scswitch command as follows.

    # scswitch -e -j DHCP- resouce
  3. Run the scswitch command to switch the DHCP resource group to another cluster node, such as node2.

    # scswitch -z -g DHCP-failover-resource-group -h node2
