A domain user account for Cluster service (all nodes must be members of the same domain)
Each node should have at least two network adapters—one for connection to the public
network and the other for the node-to-node private cluster network. If only one network adapter
is used for both connections, the configuration is unsupported. A separate private network
adapter is required for HCL certification.
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.
Use Table 4 (page 63) to determine which nodes and storage devices should be presented during
each step.

Shut down all nodes. Present the shared

Power on the next node after the first
node is successfully configured. Complete
this process for all cluster nodes.

At this point all cluster nodes should be

To configure the Cluster service on the storage system, an account must have administrative
permissions on each node.
