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 3PAR StoreServ File Controller.
Before beginning installation
Confirm that the following specifications have been met before proceeding:
• 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 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 multipath data paths for high availability
HP recommends that cluster configurations be deployed with dual data paths for high availability.
Clusters can be configured with single path, but if a failure in the path occurs, all of the node
resources will be failed to the non-affected node. Pathing software is required in configurations
where multipathing to the storage is desired or required. Multipathing software allows for datapath
failure to occur without forcing a node failover.
Checklists for cluster server installation
These checklists assist in preparing for installation. Step-by-step instructions begin after the checklists.
Network requirements
• A unique NetBIOS cluster name
• For each node deployed in the cluster the following static IP addresses are required:
One for the network adapters on the private network◦
◦ One for the network adapters on the public network
◦ One for the virtual server itself
A single static cluster IP address is required for the entire cluster.
