is installed on at least one node and that node is online. This can be accomplished through selective
storage presentation, SAN switch zoning, or having only one node online at all times.
• All soft ware components listed in the HP ProLiant Storage Server SAN Connection and
Management white paper (located on the server documentation CD) must be installed and the
fiber cables attached to the HBAs before the cluster installation is started.
• All shared disks, including the quorum disk, must be accessible from all nodes.
• 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 tha t 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 17 to determine which nodes and storage devices should be presented during each step.

To configure the Cluster service on the storage server, an account must have administrative permissions
on each node. All nodes must be member servers within the same domain. It is not acceptable to have a
mix of domain controllers and mem ber servers in a cluster.
Setting up networks
Each cluster node requires at least two network adapters—one to connect to a public network, and one
to connect to a private network consisting of cluster nodes only.
