本文详细介绍了如何通过Windows Server 2008 R2搭建高可用集群的过程，包括服务器信息准备、iSCSI目标配置、集群角色及特性添加等关键步骤，并解决了验证配置阶段出现的问题。

一、Preparation

1、Server Information

PC Name	IP Address	Function	Remark
	191.168.1.188	Domain Controller（Win2008 R2 Sp1）	Physical PC
Win2008ClusterA	192.168.1.31	Public IP Address（Win2008 R2 Sp1）	Virtual PC
Win2008ClusterA	192.168.56.31	Private IP Address
Win2008ClusterB	192.168.1.32	Public IP Address（Win2008 R2 Sp1）
Win2008ClusterB	192.168.56.32	Private IP Address
	192.168.1.30	Cluster2008 (Cluster IP Address)
	192.168.1.34	Cluster2008DTC (DTC Service)
	192.168.1.250	ISCSI Target Server （NAS4Free）	Virtual PC

2、Topological Diagram

3、Account preparation

　　Add an account named “clusteradmin”, assign with "Domain admins"、"DnsAdmins"、"Administrators"、"Domain Users"

二、Setup ISCSI Target

1、Download NAS4Free software (home site: http://www.nas4free.org/)

2、Installation is simple (just follow the menu instructions)

3、Setup ISCSI Target via Web GUI as below (not configure the ISCSI Target Auth )

4、Check ISCSI Target status

三、Discovery ISCSI Target & online the Disks

1、Discovery ISCSI Target

2、Connect the Targets

3、Online the Disk

Sharedisk---- assign S driver letter

Quorum ----- assign Q driver letter

四、Add Roles(Both win2008clusterA and win2008clusterB)

1、Select and Check the "Application Server", then click "Next "

2、Check ".Net Framework 3.5.1"、 "Incoming Remote Transactions"、"Outgoing Remote Transaction", then click "Next"

3、Finish the installation & close

五、Add Features(Both win2008clusterA and win2008clusterB)

1、Select and check "Failover Clustering", then click "Next"

2、Finish installation & close

六、Validate a Configuration before creating a cluster

1、Click "Validate a Configuration…" to open the wizard.

2、Add the Nodes to Validate(Here Win2008clusterA & Win2008clusterB for example)

3、Validation result

Here I got the error information after validation，because first time I used the ISCSI target software(iscsitarget) which does not support SCSI-3 Persisitent Reservation.

4、Ignore the errors (Only for testing purpose) to create the Cluster with single node (Win2008ClusterB).

As the ISCSI Disk function limitation，the cluster can't make the cluster disk online.

ISCSItarget download URL: http://iscsitarget.sourceforge.net

Finally, I chose the NAS4Free which supports SCSI-3 Persisitent Reservation.Re-configation as step three (enable the disk online) on both Win2008ClusterA and Win2008ClusterB.

Re-validate Clustering Configuration, then I got a success validation result.
