Do not place paired adapters on the same IP network unless you are going to use
adapter teaming or adapter load balancing.
Verifying network connectivity and names resolution
Verify network connectivity and names resolution after you have installed clustering
on the joining node.
To verify that the private and public networks are communicating properly:
1. Click
Start
→
Run , type cmd in the text box, and click OK to bring up an
MS-DOS prompt.
2. Type ping ipaddress where ipaddress is the IP address for the corresponding
network adapter in the other node, and press Enter .
For example, assume that the IP addresses are set as follows:
Table 3. Example of local area connection names and network adapter IP addresses
Node Local area connection name Network adapter IP address
1 Private 10.1.1.1
1 Public 1 192.168.1.12
1 Public 2 192.168.2.12
2 Private 10.1.1.2
2 Public 1 192.168.1.13
2 Public 2 192.168.2.13
In this example, you would type ping 192.168.1.12 and ping 192.168.2.12 for the
first node, and you would type ping 192.168.1.13 and ping 192.168.2.13 for the
joining node. You can do this from any machine that is physically connected to the
network of each node.
To view the addresses, use the ipconfig command on each node:
1. Click Start
→
Run , type cmd in the text box, and click OK to bring up an
MS-DOS prompt.
2. Type ipconfig /all and press Enter . IP information should appear for all network
adapters in the machine.
Checking or changing the network binding order
The clustering function requires the following binding order:
v
Private
v
Public 1
v
Public 2
v
.
.
.
The top-most connection is first in the binding order. Typically, this is the most
frequently used network adapter.
To check the binding order and change it:
1. From the desktop, right-click My Network Places and then select Properties .
2. Select Advanced Settings from the Advanced menu.
3. Reorder the position of the adapters by selecting them, then pressing the up or
down arrow keys, then clicking OK .
