Shared disk requirements

NOTE:
Do not allow more than one node access the shared storage devices at the same time until Cluster
service is installed on at least one node and that node is online. This can be accomplished through
selective storage presentation, SAN zoning, or having only one node online at all times.
• All shared disks, including the Quorum disk, must be accessible from all nodes. When testing
connectivity between the nodes and the LUN, only one node should be given access to the LUN
at a time.
• All shared disks must be configured as basic (not dynamic).
• All partitions on the disks must be formatted as NTFS.

Cluster installation

During the installation process, nodes are shut down and rebooted. These steps guarantee that the
data on disks that are attached to the shared storage bus is not lost or corrupted. This can happen
when multiple nodes try to simultaneously write to the same disk that is not yet protected by the cluster
software.
