NOTE:
AppleTalk is not supported on clustered disk resources. AppleTalk requires local memory for volume
indexing. On failover events, the memory map is lost and data corruption can occur.

Preparing for cluster installation

This section provides the steps necessary to cluster HP ProLiant storage servers.

Before beginning installation

Confirm that the following specifications have been met before proceeding:
• The SAN Connection Guide must be completed and all the necessary software components for
connecting to the desired storage must be installed before the configuration of cluster services.
• It is required that at least one LUN has been presented for the configuration of the Quorum
disk. This LUN must be created from shared storage and must be at least 50 MB. (500 MB is
recommended). Additional LUNS may also be presented for use as shared disk resources.
• Cluster configurations should be deployed with dual data paths for high availability. Dual data
paths from each node enable a path failure to occur that does not force the failover of the node.
Clusters can be configured with single path, but if a failure in the path does occur, all of the node
resources will be failed to the non-affected node.

Using Secure Path

Pathing software is required in configurations where multipathing to the storage is desired or required.
For clustered products HP recommends maintaining two paths to the data as pathing software allows for
datapath failure to occur without forcing a node failover. Secure Path is fully licensed and in contained
