Do not partition a disk into separate drives. Microsoft Cluster Server Software will only
manage one partition per disk.
Repeat steps 1 through 3 to create a partition for each disk array to be shared by the cluster.
From Disk Administrator's Partition menu, choose Commit Changes Now, then choose Yes to
save changes and OK when prompted.
In the following example, Disk 2 has been partitioned and Disk Administrator assigned
the next sequential letter to the disk array.
