Storage planning

For clustering, a basic disk must be designated for the cluster and configured as the Quorum disk.

Additional basic disks are presented to each cluster node for data storage as physical disk resources.

The physical disk resources are required for the basic disks to successfully work in a cluster environment,

protecting it from simultaneous access from each node.

The basic disk must be added as a physical disk resource to an existing cluster group or a new cluster

group needs to be created for the resource. Cluster groups can contain more than one physical disk

resource depending on the site-specific requirements.

NOTE:

The LUN underlying the basic disk should be presented to only one node of the cluster using selective

storage presentation or SAN zoning, or having only one node online at all times until the physical resource

for the basic disk is established.

In preparing for the cluster installation:

• All software components listed in the HP ProLiant Storage Server SAN Connection and Management

white paper (located on the HP web site at http://h20000.www2.hp.com/bc/docs/support/

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.

Network planning

Clusters require more sophisticated networking arrangements than a stand alone storage server. A

Windows NT domain or Active Directory domain must be in place to contain the cluster names, virtual

server names, and user and group information. A cluster cannot be deployed into a non domain

environment.

All cluster deployments have at least six network addresses and four network names:

• The cluster name (Unique NETBIOS Name) and IP address

• Node A's name and IP address

• Node B's name and IP address

• At least one virtual server name and IP address for virtual server A

• Cluster Interconnect static IP addresses for Node A and Node B

In multi-node deployments, additional network addresses are required. For each additional node,

three static IP addresses are required.
