7 Click OK and exit the network adapter properties.
8 Click the Start button and select Programs → Administrative
Tools
→ Cluster Administrator .
9 Click the Network tab.
10 Verify that a new resource labeled "New Cluster Network" appears in the
window.
To rename the new resource, right-click the resource and enter a new
name.
11 Move all cluster resources back to the original node.
12 Repeat step 2 through step 11 on each node.
NOTE: For each node, ensure that you assign the IP address on the same
subnet as you did on the first node.
If the installation and IP address assignments have been performed correctly,
all of the new network adapter resources appear online and respond
successfully to ping commands.
Changing the IP Address of a Cluster Node on the
Same IP Subnet
NOTE: If you are migrating your nodes to a different subnet, take all cluster
resources offline and then migrate all nodes together to the new subnet.
1 Open Cluster Administrator .
2 Stop MSCS on the node.
The Cluster Administrator utility running on the second node indicates
that the first node is down by displaying a red icon in the
Cluster Service
window.
3 Reassign the IP address.
4 If you are running DNS, verify that the DNS entries are correct
(if required).
5 Restart MSCS on the node.
The nodes re-establish their connection and Cluster Administrator
changes the node icon back to blue to show that the node is back online.
