When all drives have been assigned drive letters and formatted, the identical drive let- ters for the shared drives must be assigned on the second node. To do this, enter the Disk Administrator on the second node, right-click each drive, and assign the same drive letter to each drive that was assigned on the first node.

NOTE: Do not use Disk Administrator to set up RAID levels on the shared storage subsystem hard-disk drives.
