3 Installing and Configuring Failover Manager : 3.3 Using Failover Manager with Virtual IP Addresses

Failover Manager uses the efm_address script to assign or release a virtual IP address. By default, the script resides in:
# efm_address assign interface_name IPv4_addr netmask
# efm_address assign6 interface_name IPv6_addr prefix_len
# efm_address release6 interface_name IPv6_addr prefix_len
interface_name matches the name specified in the virtualIp.interface parameter in the cluster properties file.
IPv4_addr or IPv6_addr matches the name specified in the virtualIp parameter in the cluster properties file.
netmask or prefix_len matches the value specified in the virtualIp.netmask parameter in the cluster properties file.
You must invoke the efm_address script as the root user. The efm user is created during the installation, and is granted privileges in the sudoers file to run the efm_address script. For more information about the sudoers file, see Section 3.1, Extending Failover Manager Permissions.
2. Run the efm_address assign command on the Master node to assign the VIP and then confirm with ifconfig:
4. Use the efm_address release command to release the address on the master node and confirm the node has been released with ifconfig:
