Setting Up Shared Disks
Warning:  Make sure that Windows 2000 Advanced Server or Windows 2000 Datacenter Server and the
Cluster Service are installed and running on one node before you start an operating system on
another node. If the operating system is started on other nodes before you install and configure
Cluster Service and run it on at least one node, the cluster disks will have a high chance of
becoming corrupted.
To continue, power off all nodes. Power up the shared storage devices. Once the shared storage
device is powered up, power up node one.
Quorum Disk
The quorum disk stores cluster configuration database checkpoints and log files that help manage
the cluster. Windows 2000 makes the following quorum disk recommendations:
•  Create a small partition [Use a minimum of 50 megabytes (MB) as a quorum disk. Windows
2000 generally recommends a quorum disk to be 500 MB.]
•  Dedicate a separate disk for a quorum resource. The failure of the quorum disk would cause
the entire cluster to fail; therefore, Windows 2000 strongly recommends that you use a volume
on a RAID disk array.
During the Cluster Service installation, you have to provide the drive letter for the quorum disk.
Note: 
For our example, we use the letter for the quorum disk drive letter.
