Creating a LUN as a quorum on a Windows 2003 cluster

You can use SnapDrive to create and configure a LUN as a cluster quorum disk on a new Windows Server 2003 cluster.

Before you begin

When you create a Windows cluster whose quorum disk will be a LUN, you must ensure the following:

You have up to eight host machines with Windows Server 2003 Standard Edition or Enterprise Edition installed. For more information about installing the Windows Server 2003 software, see your Microsoft documentation.
Your storage system is running at least Data ONTAP 7.1.
Make sure that the following are installed on all nodes of the cluster:
- Appropriate FC HBA drivers, WHQL signed iSCSI HBA drivers, or the Microsoft iSCSI Software Initiator drivers
- Either the FC or iSCSI Host Utilities, depending on your configuration
- SnapDrive for Windows
If you are using the Microsoft iSCSI software, establish iSCSI connections to the storage system from all nodes of the cluster using each node’s MMC.
Because this LUN will be designated as a quorum disk later in this procedure, you must create a disk of adequate size according to Microsoft’s recommendations.

Steps

Create a shared LUN on node 1 and note the path and drive letter you assign to the LUN.

On node 1, launch the Windows Server 2003 Cluster Administrator.

If the Cluster Administrator is launched...	Then...
For the first time on this node, you are prompted to specify the action to take.	Select Create New Cluster from the Action drop-down list.
Subsequently, it does not prompt you to specify the action to take.	In that case, select File > New > Cluster from the Cluster Administrator.

The New Server Cluster Wizard is displayed.

In the New Server Cluster Wizard, follow the prompts to type the following information:
- Windows domain name and cluster name
- The node that will be the first node in the cluster
  The node you are working on currently should be the selected node in the wizard.
- IP address for the server cluster
- User name and password for the cluster service account
  Note: Note the user name and password you enter; you need it in a later step in this procedure.
After you have entered the above information in the New Server Cluster wizard windows, the Proposed Cluster Configuration panel is displayed.

In the Proposed Cluster Configuration panel, do one of the following:

If...	Then...
The LUN you created in Step 1 is automatically selected as the quorum disk	Go to Step 5.
The LUN you created in Step 1 is not selected as the quorum disk	Click the quorum button. Change the drive letter to that of the LUN and click Next.

Step through the remaining panels of the New Server Cluster Wizard.
After you finish using the New Server Cluster Wizard, the first node in the cluster is up and functional.
Go to the Windows host that will be the next node in the cluster and, from SnapDrive, connect to the LUN you created in Step 1 from this node, using the path and drive letter you noted in Step 1.
Note: The Shared disk option is automatically selected.

SnapDrive prompts you for the cluster name.
Enter the cluster name you created in Step 3. Click OK.
Launch the Windows Server 2003 Cluster Administrator and perform the following actions:
1. Select File > Open Connection.
2. Select Add Nodes to Cluster.
3. Type the name of the cluster (as in Step 3)
4. Click Next.
The Add Nodes wizard is displayed with the name of the node on which you are currently working.
In the Add Nodes wizard, follow the prompts to perform the following tasks in the wizard panels:
1. If the name of the node on which you are working currently is not displayed, type the name of the node or click Browse to find the node. Then click Add to add the node to the list.
2. Select Advanced > Advanced (minimum) Configuration.
3. Enter the password for the cluster service account.
  Note: This password should be the same as the one you entered in Step 3.
After you enter the information, the Proposed Cluster Configuration panel is displayed.

In the Proposed Cluster Configuration panel, do one of the following:

If the proposed cluster configuration ...	Then...
Requires no changes	Follow the Add Nodes wizard prompts to complete the remaining steps of the wizard.
Requires changes	Make the appropriate changes, and then follow the Add Nodes wizard prompts to complete the remaining steps of the wizard.

The node is added to the cluster.

Use the Cluster Administrator to verify that the cluster is functioning correctly by performing a “move group” operation from one node to the other and then back to the original node.
Note: You should perform the “move group” operation for all nodes in the cluster to ensure proper operation.

If... Then...

The node you added to the cluster was the last node You are done.

The node you added to the cluster was not the last node Go to Step 6.

If...	Then...
The node you added to the cluster was the last node	You are done.
The node you added to the cluster was not the last node	Go to Step 6.

Result

You have added the desired number of nodes to a Windows Server 2003 cluster. The server cluster is up and operational. Now you can create shared disks for your applications.

Note: Microsoft recommends that you not add new shared resources to Cluster Group once it has been created. If you add resources to the group, you may not be able to administer the cluster effectively. For more information, see Microsoft knowledge base article 168948.
