Cluster Installation
During installation, some nodes are shut down, and other nodes are
rebooted. This ensures uncorrupted data on disks attached to the shared
storage bus. Data corruption can occur when multiple nodes try to write
simultaneously to the same disk that is not yet protected by the cluster
software.

All shared disks, including the quorum disk, must be physically
attached to the shared bus.
All disks attached to the shared bus must be visible from all nodes.
You can check this at the setup level in the BIOS Configuration utility,
which is accessed by pressing <Ctrl> <M>. See
"Installing SCSI Drives," page
Each SCSI device must have a unique SCSI identification number
assigned to it, and each device must be terminated properly. See the
storage enclosure manual for information about installing and
terminating SCSI devices.
Configure all shared disks as basic (not dynamic).
Format all partitions on the disks as NTFS.
