Q. How can I check which disk is the quorum disk for my Windows Server 2003 cluster?

A. Start Cluster Administrator, then right-click the cluster's name and select Properties. Select the Quorum tab, and you'll see the current quorum disk in the "Quorum resource" drop-down list, which the Figure shows. If you want to change the quorum disk, select a new quorum resource from the list. You can find more detailed information about quorum disks in the Microsoft article "How to Change the Quorum Disk Designation."
