Q: Why do I see DNS Failure on the iSCSI network name cluster resource?

Sunday, June 13th, 2010

A: The default network properties will force the Network Name resource to attempt to register itself with a DNS Server. This may result in slower than expected iSCSI resource group movement between Windows Storage Server 2008 cluster nodes. The recommendation is to remove the DNS registration requirements by adjusting the appropriate network properties.

1. Open the Network Sharing Center on one of the Windows Storage Server 2008 systems.

2. Select Manage network connections.

3. Select Properties for the iSCSI Network.

4. Select Properties for Internet Protocol Version 4 (TCP/IPv4).

5. Select the Advanced tab.

6. Select the DNS tab.

7. Deselect the Register this connection’s addresses in DNS.

8. Close the Properties for the iSCSI Network.

9. If there are any additional iSCSI networks, repeat Step 3 to 8 for each one.

Should I disable NetBIOS over TCP/IP on my Windows Server 2008 R2 Cluster Shared Volume (CSV) cluster networks?

Sunday, June 13th, 2010

Yes. To improve performance, it’s recommended that you disable NetBIOS over TCP/IP on your cluster network NIC and other dedicated-purpose NICs, such as for iSCSI and Live Migration. NetBIOS isn’t used in Server 2008 R2 clusters.

To disable NetBIOS over TCP/IP, access the IPv4 properties of your network adapter. To do this, open the Network and Sharing Center, select Change Adapter Settings, right-click the network connection, and select Properties. Select Internet Protocol Version 4 (TCP/IPv4) and click the Advanced button in the displayed dialog.

Select the WINS tab and select the Disable NetBIOS over TCP/IP. Perform this on all network connections that aren’t general purpose management/connectivity NICs, and perform it on all nodes in the cluster.

Additionally, make sure you enable jumbo packets on all network adapters, if you haven’t done so already.

Make sure you don’t disable Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks on the NIC used for CSV—they’re requirements. You could disable these for networks used for iSCSI and other dedicated purposes.
