•
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 software components listed in the HP ProLiant Storage Server SAN Connection and Management
white paper (located on the HP web site at
SupportManual/c00663737/c00663737.pdf) 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. 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

to determine which nodes and storage devices should be presented during each step.
