You can use the vxlicinst command to add the VCS license key on each node. If you have VCS already installed and configured and you use a demo license, you can replace the demo license.
To update product licenses
On each node, enter the license key using the command:
# cd /opt/VRTS/bin
# ./vxlicinst -k XXXX-XXXX-XXXX-XXXX-XXXX-XXX
