Chapter 7 Cluster Installation and Configuration 83
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 E for the quorum disk drive letter.
