SCC -- Single Copy Cluster

Shared Resources are owned by only one server at any time.

Domain Layout

Both Geek and Dove have Windows 2003 Server Enterprise edition installed.

Geek is promoted as DC.

Domain user: clusterAdministrator is created.

Create two virtual servers in member server: dove;

Install Windows 2003 server on both server1 and server2.

NIC

Member server: Dove

Virtual Server: Server1

Virtual Server: Server2

Internal NICs: Internal 10.0.0.1, Internal 10.0.0.2, and Internal 10.0.0.3

uncheck "client for Microsoft Network"
uncheck "File & Printer Sharing For Microsoft Network"
uncheck "Register this connection address in DNS"

uncheck "Enable LMHOSTS lookup

Join Dove, server1, and server2 to domain 1ASK2.COM.

Create 4 more virtual disks: 1GBdisk2.vhd, 1GBdisk3.vhd, 1GBdisk4.vhd, 1GBdisk4.vhd

Both server1 and server2 will have access and control of all four disks, as shown below.

Server1 and server2:attach virtual hard disks to virtual SCSI adapters

For two-node cluster creation, you must follow the Turn On/Off sequence. If both nodes run at same time before the cluster is created, the shared disks will be corrupted.

Turn on Server1

Open Disk Management Console, follow the wizard to initialize the shared SCSI drives (4), don't convert them to dynamic (Cluster supports only basic disks), create one primary partition for each disk with the whole disk space, and format them as NTFS. I use the drive letters: W, X, Y, Z (Microsoft recommends the higher drive letters should be used).

Users and Computers console and add the VIP\ClusterAdministrator to Local Administrators group;

Backup SystemState; When you configure and test clustering, it is possible that you cannot open the existing cluster and cannot create a new cluster.

Turn down server1

Turn on server2

Open Disk Management console to initialize the SCSI drives; this time, you don't need to create partitions and format them. Even though there are no drive letters for the drives, they are in SCSI drives.

Turn down server2

Turn on Server1

CLuster Administrator to create a new cluster:MyCluster

Cluster IP:192.168.1.200

Cluster Service Account: VIP\ClusterAdministrator

Quorum:drive X

After the cluster: myCluster is created, turn on server2.

Cluster Administrator--Add a new node (Server2) to MyCluster

The warning message does not matter. This is because all the shared disks are currently owned by Node1. Microsoft Cluster uses the share-nothing architecture. Node2 does not have access to the shared storage at the moment.

Set the preferred Owner to server1 and server2 for Cluster Group, Group 0, group 1, and group 2.

At server1:

Move resources in Group 1 and Group 2 to Group 0;
Rename the resource names according the labels of physical disks in My Computer.

Delete Group 1 and Group 2;

Create MSDTS resource

The MSDTC resource depends upon Network Name resource and physical disk resource. Microsoft recommends that a independent disk should be used. Group 0 does not have Network Name resource.  In this scenario, msdts resource can only be created in Cluster Group.

Test the failover of resources in a cluster

Test 1:

Resources: msdts Y:, data1 X:, and data2 W: are owned by SERVER2.

Test 2:

Shutdown server1

The owner of all resources is SERVER2.
