Configure The Private Network Adapter - Compaq 230039-001 - StorageWorks NAS Executor E7000 Model 904 Server Installation Manual

[Enter your Document Title]
Each cluster node requires at least two network adapters—one to connect to a
public network, and one to connect to a private network consisting of cluster
nodes only.
The private network adapter establishes node-to-node communication, cluster
status signals, and cluster management. Each node's public network adapter
connects the cluster to the public network where clients reside.
Verify that all network connections are correct, with private network adapters
connected to other private network adapters only, and public network adapters
connected to the public network.

Configure the Private Network Adapter

The following procedures are Best Practices provided by Microsoft and should
be configured on the private network adapter.
•
On the General tab of the private network adapter, ensure that only TCP/IP is selected
•
Under the advanced settings for the private network adapter, select the DNS Tab. Ensure
that the register this connections address in DNS is not selected.
•
Open the advanced tab for the Ethernet card used for the private network adapter.
Ensure that the Link Speed and Duplex is set to 100Mps/Full Duplex
•
If a crossover cable is used for the private adapter and since one node will be powered
down during the cluster installation. The private network adapter will be in a
disconnected state during installation, the Cluster service does not detect the adapter
because there are no protocols bound to the adapter. If Media Sense is disabled the
network adapter still shows the "disconnected" status, but the cluster installation process
can detect the adapter as available for cluster communication

Note: If the private network connection is made using a crossover cable, then the
procedures outlined in Knowledge Base (KB) article
(http://support.microsoft.com/support/kb/articles/Q242/4/30.ASP) should be
followed and the node rebooted prior to installing the Cluster service. If this procedure is
not completed, and the second node is powered off while installing the Cluster service
on the first node, the private network adapter may not be detected. This will prevent
configuring the adapter during the Cluster service installation. However, after the Cluster
