8. Follow the onscreen instructions to install the NIC 3 driver in node 1.
9. Enter the NIC 3 IP address, ensuring that the network ID portion of the IP
address is not identical to NICs 1 and 2.
For example, if NICs 1 and 2 in node 1 have an address of 192.168.1.101 and
192.168.1.102 with subnet masks of 255.255.255.0, respectively, you might enter
the following IP address and sub-net mask for NIC 3:
IP Address: 192.168.1.111
Subnet Mask: 255.255.255.0
NOTE: Be sure to use an IP address with the same IP network (the third octet in
the IP address) as the first and second NICs.
10. Click OK, exit the Control Panel, and restart node 1.
The Windows 2000 desktop appears.
11. Click the Start button, point to Programs, select Administrative Tools, and then
select Cluster Administrator.
12. Click the Network tab and verify that New Cluster Network appears as a new
resource.
13. Select the next node in the cluster to become node 2.
14. Move all cluster resources to node 2 (the next cluster node) and repeat steps 4
through 12 on node 1 for the remaining nodes in your cluster.
NOTE: Be sure to assign NICs 1and 2 with the same IP network (the third octet in
the IP address) as NIC 3 in node 1. For example you could use 192.168.1.112,
thereby continuing the IP address numbering scheme shown in step 9.
If the installation and IP address assignments have been performed correctly, all of
the new NIC resources will appear online and respond to ping commands in a
Command Prompt window. Additionally, you can also use Cluster Administrator to
display the status of the NIC resources.
Changing the IP Address of a Cluster Node
NOTE: To change the IP address of a cluster node, you must stop Cluster Service on
the node, reassign the IP address, and then restart Cluster Service.
When a cluster node is down or the Cluster Service is stopped on one of the remain-
ing cluster node(s), the Cluster Administrator utility running on one of the remaining
node(s) indicates that a cluster node is down by displaying a red icon for the failed
node. When the failed node is restarted, the cluster nodes reestablish their connec-
tion and the Cluster Administrator changes the failed cluster node icon back to blue to
show that the cluster node is back online.
