To configure the hardware

1. Install the required network adapters, and SCSI controllers or Fibre Channel HBA.
2. Connect the network adapters on each system.

   To prevent lost heartbeats on the private networks, and to prevent the Microsoft cluster from mistakenly declaring a system down, Veritas recommends disabling the Ethernet autonegotiation options on the private network adapters. Contact the NIC manufacturer for details on this process.

3. Use independent hubs or switches for the private heartbeats. You can use cross-over Ethernet cables for two-node clusters. Verify that each system can access the storage devices.
4. Verify that each system recognizes the attached shared disk and that the attached shared disks are visible.

To verify the DNS settings and binding order for all systems

1. Open the Control Panel by clicking Start > Control Panel.

   On Windows 2012 operating systems, use the Settings menu from the Start screen.

2. Click Network and Internet, and then click Network and Sharing Center.
3. In the Network and Sharing Center window, on the left side of the screen under Tasks, double-click Manage network connections.
4. Ensure that the public network adapter is the first bound adapter by following these steps sequentially:

   • In the Network Connections window, click Advanced > Advanced Settings.

   • In the Adapters and Bindings tab, verify that the public adapter is the first adapter in the Connections list. If necessary, use the arrow button to move the adapter to the top of the list.

   • Click OK.

5. Open the Public status dialog box by doing one of the following in the Network Connections window:

   • Double-click the adapter for the public network.

   • Right-click the adapter for the public network and click Status.

   • Select the adapter for the public network and click View status of this connection in the toolbar.

   When enabling DNS name resolution, make sure that you use the public network adapters, and not those configured for the private network.

6. In the Public Status dialog box, on the General tab, click Properties.
7. On the Public Properties dialog box, on the General tab:

   • Select the Internet Protocol Version 4 (TCP/IPv4) check box.

   • Click Properties.

8. Select the Use the following DNS server addresses option.
9. Verify the correct value for the IP address of the DNS server.
10. Click Advanced.
11. In the DNS tab, make sure the Register this connection's address in DNS check box is selected.
12. Make sure the correct domain suffix is entered in the DNS suffix for this connection field.

    To find the domain suffix, click Start > Control Panel > System. The domain suffix is listed in the "Computer Name, domain, and workgroup settings" section.

13. Close the window.
