Duplicate IP Address Causes Comatose Volume Resource

When attempting to online a cluster services volume resource, it goes comatose. The volume resource's load.out file and /var/log/messages show the following, where CLP21_SERVER is the volume resource name, CLP21 is the pool name and VOL1 is the volume associated with the volume resource. :

The NCP Server's IP address (192.168.143.21) was already in use when the volume resource was attempting to be brought online. Likewise if the volume resource is offline, but it's IP address is currently in use, the resource will go comatose if you attempt to online it.

Unbind the NCP Server's IP address from the server on which it is currently bound, or reconfigure your volume resource to use a different IP address.
