HP ProLiant Storage Server User Guide (440584-001, February 2007)

a client cannot use the virtual name or virtual IP address to access the share since the protocol cannot
failover with the cluster group. The client must wait until the initial node is brought back online to access
the share.
HP recommends p lacing cluster aware and non cluster aware protocols on different file shares.

is not supported on clustered disk resources. AppleTalk requires local memor y for volume
indexi ng. 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 Ser vers.
Before beginning installation
Confirm that the following specifications have been met before proceeding:
• The procedures in the HP ProLiant Storage Server SAN Connection and Management white
paper (located on the HP web site at h
ttp://h20000.www2.hp.com/bc/docs/support/
SupportManual/c00663737/c00663737.pdf) must be com pleted and all the necessar y software
components for connecting to the d esired storage must be installed before the configuration of
cluster services.
• The Quorum disk has been created from shared storage and is 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 oc cur that do es 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.
