16. In User name, type iscsiuser, in Secret and Confirm secret type iscsiPassw0rd!, and then click OK
Assign storage devices to the iSCSI target
The Windows iSCSI Software Target makes use of virtual hard disks (VHD’s) as the source for storage. Each VHD is exposed as a volume that is available to the iSCSI Initiator. In this task you will assign three existing VHD’s as storage for the ISCSI target.
1. Ensure you are logged on to SAN-01 as Administrator with a password.
2. In iSCSITarget, expand iSCSI Targets, and then click SAN-01.
3. On the Acton menu, click Add Existing Virtual Disk to iSCSI Target.
4. In the Add Virtual Disk dialog box, click Virtual Disk 0, and then click OK
5. Repeat steps 2 through 4 to add Virtual Disk 1, and Virtual Disk 2.
Configure the iSCSI initiators’ on each node
Windows Server 2008 includes an iSCSI initiator. In this task you will configure the iSCSI Initiator to communicate with the iSCSI target you created in the previous exercise. You will then connect to the storage devices and bring them online on each cluster node. On Windows Server 2008 Core, the initiator is configured using the ISCSICLI command. This command is included in Windows Server 2008 as well, along with a control panel applet that allows you to configure the initiator through the user interface. In this task you will add the target portal, the target, and login to the target. You will then use the DISKPART command to import the storage and create partitions that Windows can use.
1. Ensure you are logged on to NODE-01 as Domain\Administrator with a password
2. In the Command Prompt, type the following commands, pressing ENTER after each one. This sequence of commands will configure the iSCSI initiator in each node, and import the storage on the SAN.

Exercise 2: Creating a Windows Failover Cluster
In this exercise you will create a new Windows Failover Cluster. You will begin by configuring two nodes. The Windows Failover Clustering feature has already been installed to save time. You will first review a cluster validation report. The failover clustering administrator tool optionally performs an extensive series of tests to ensure that the configuration of the two nodes will support a failover cluster. You will then use the Failover Cluster Manager to create a new failover cluster.
Verifying the failover clustering feature has been installed.
Windows Failover Clustering is a Windows Server 2008 feature that can be installed on a full server or on server core. On a full server it can be verified by viewing the installed features in Server Manager. On server core installations, it can be verified using the OCLIST command.
1. Ensure you are logged on to NODE-01 as Domain\Administrator with a password.
2. In the Command Prompt, type the following command, and then press ENTER.
OCLIST Find "Cluster"
Validating a cluster configuration
The cluster validation wizard performs an extensive series of tests to ensure that your system is correctly configured and prepared to function as a failover cluster. The cluster validation wizard results can be saved as a report. Performing the full set of validation tests can take an extended period of time.
a) Ensure you are logged on to SRV-01 as Domain\Administrator with a password.
b) On the Start Menu, point toAdministrative Tools and then click Failover Cluster Management.

17. On the Confirmation page, click Close.
Create a Highly Available DHCP Server
In this task you will create a highly available DHCP server by adding the DHCP service to the cluster. The failover clustering management tool will verify that each node is a candidate for a highly available DHCP service by ensuring that DHCP is installed on each node.
1. In Failover Cluster Management, click Services and Applications, and then in the Actions pane, click Configure a Service or Application.
2. In the High Availability Wizard wizard, click Next, select DHCP server, and then click Next.
3. On the Client Access Point page, in Address, type "IP Address", and then click Next.
4. On the Select Storage page, check Cluster Disk 3, and then click Next.
5. On the Confirmation page, click Next, and then once the cluster has been configured, click Finish.
Verify the Highly Available DHCP Server is Configured
In this task you will verify that the DHVP server is available for configuration using the DHCP management tool on SRV-01
1. Ensure you are logged on to SRV-01 as Domain\Administrator with a password.
2. On the Start menu, point to Administrative Tools, and then click DHCP.
3. In DHCP, on the Action menu, click Add Server.
4. In the Add Server dialog box, in This Server, type clusterDHCP.Domain.com, and then click OK.
5. In DHCP, click ClusterDHCP.Domain.com.
Exercise 4: Testing the Failover Cluster
In this exercise you will perform a series of tests to ensure that your cluster is functioning properly. You will first ensure that you can access the cluster using the shared resource name. Then you will perform a manual failover. Manual failover is generally performed for scheduled downtime or maintenance. Finally you will test to ensure that automatic failover takes place.
Verify File Server Cluster Connectivity
In this task you will use Windows Explorer to navigate to the shared cluster resource.
1. Ensure you are logged on to SRV-01 as Domain\Administrator with a password.
2. On the Start menu, in Start Search, type file://clusterfs.domain.com/auditing and then press ENTER.
3. Verify that Windows Explorer opens and displays the contents of the Auditing folder.
The auditing folder will be empty.
Verify Manual Failover of the Cluster
To perform a test of manual failover, you will connect to one node in the cluster and then move the file server resource to the other node.
1. Ensure you are logged on to SRV-01 as Domain\Administrator with a password "" and that you have Failover Cluster Management open.
2. In Failover Cluster Management, under Services and Applications, click ClusterFS.
3. In the contents pane, note the value of Current Owner.
4. In the Actions pane, point to Move this service or application to another node and then click Move to NODE-01.
5. In the Please confirm action dialog box, click Move ClusterFS to NODE-01.
In some situations, the current owner value may be different. If the current owner value NODE-01, then, move the service to NODE-02. Once this process is completed, move the service back to NODE-01 to complete the remaining tasks. When the Current Owner value changes to the other node, the cluster has failed over.
6. In Windows Explorer, in the Auditing folder, press F5 to verify you can access the cluster resource.
Verify Automatic Failover of the Cluster
Automatic failover occurs when one of the cluster nodes is no longer responsive. In this task you will simulate a network failure of one node by disabling the network interface. You will then observe the results as the cluster resource fails over to the functioning node.
1. Ensure you are logged on to SRV-01 as Domain\Administrator with a password, and that you have Failover Cluster Management open.
2. In Failover Cluster Management, navigate to Cluster.Domain/Services and Applications, and then click ClusterFS.
3. In the contents pane, note the value of Current Owner.
4. Ensure you are logged on to NODE-01 as Domain\Administrator with a password.
5. Disabled the Network card of Node -01.
6. Switch to SRV-01 and view Failover Cluster Management. Note that the service fails over to NODE-02 automatically.
This automatic failover may take several minutes. During this time the Failover Cluster Management console may hang, or appear unresponsive.
7. Switch to NODE-01.
8. Enable the Network Cards of Node-01.
Exercise 5: Administering a Cluster using Cluster.exe
Cluseter.exe is the command line interface included in Windows Server 2008 Failover clustering. The cluster.exe tool allows administrators to perform almost all cluster configuration and management tasks, and makes it easy to create automation scripts which automate tasks and respond to cluster events. In this exercise you will perform three common tasks in a Cluster. You will first evict a node from a cluster. You will then add a new node to a cluster, and finally you will perform manual failover of a cluster resource.
Removing a Node From the Cluster Using Cluster.exe
In this task you will use the Cluster.exe command to remove a node from a cluster. This process is referred to as eviction.
1. Ensure you are logged on to NODE-01 as Domain\Administrator with a password and that you have a command prompt window open.
2. In the Command prompt window, type the following command, and then press Enter.
Cluster NODE NODE-01 /EVICT
Adding a Node to a Cluster
In this task you will add the evicted node back into the cluster. This command can be used when you want to automate the addition of nodes.
1. Ensure you are logged on to NODE-02 as Domain\Administrator with a password and that you have a command prompt window open.
2. In the Command prompt window, type the following command, and then press Enter.
Cluster /add /node:NODE-01
Manually Failing over a Resource
In this task you will perform manual failover of the cluster. This command can be used in scripts that are used during system maintenance.
1. Ensure you are logged on to NODE-02 as Domain\Administrator with a password and that you have a command prompt window open.
2. In the Command prompt window, type the following command, and then press Enter.
Cluster GROUP ClusterFS /move:node-01
