Configuring the storage hardware and network
Use the following procedures to configure the hardware and verify DNS settings. Repeat this procedure for every node in the cluster.
To configure the hardware
- Install the required network adapters, and SCSI controllers or Fibre Channel HBA.
- Connect the network adapters on each system.
To prevent lost heartbeats on the private networks, and to prevent VCS 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.
Veritas recommends removing TCP/IP from private NICs to lower system overhead.
- Use independent hubs or switches for each VCS communication network (GAB and LLT). You can use cross-over Ethernet cables for two-node clusters. LLT supports hub-based or switch network paths, or two-system clusters with direct network links.
- Verify that each system can access the storage devices. 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
- Open the Control Panel by clicking .
- Click , and then click .
- In the Network and Sharing Center window, on the left side of the screen under Tasks, click .
- Ensure the public network adapter is the first bound adapter by following these steps sequentially:
In the Network Connections window, click .
In the Adapters and Bindings tab, verify the public adapter is the first adapter in the list. If necessary, use the arrow button to move the adapter to the top of the list.
Click .
- 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 .
Select the adapter for the public network and click in the toolbar.
When enabling DNS name resolution, make sure that you use the public network adapters, and not those configured for the VCS private network.
- In the Public Status dialog box, on the General tab, click .
- In the Public Properties dialog box, on the General tab:
- Select the option.
- Verify the correct value for the IP address of the DNS server.
- Click .
- In the DNS tab, make sure that the check box is selected.
- Make sure that the correct domain suffix is entered in the field.
- Click .
