HP 3PAR Cluster Extension Software Administrator Guide (5697-0925, May 2011)

NOTE: File Share Witness support:
• Windows Server 2003 (Service Pack 1 and later) supports only two node clusters when using
File Share Witness.
• Windows Server 2003 Service Pack 2 supports MNS with File Share Witness by default.
• When using Microsoft Windows Server 2003 Service Pack 1 (SP1)-based server cluster or
Windows Server 2003 R2-based server cluster, you must apply a Microsoft patch to support
MNS with File Share Witness. See your Microsoft documentation for more information.
HP 3PAR InForm Management Console or HP 3PAR InForm CLI
HP 3PAR InForm Management Console or HP 3PAR InForm CLI is used to create virtual volumes
and configure the HP 3PAR storage system.
IP network considerations
HP 3PAR CLI is essential to Cluster extension which communicates with the HP 3PAR storage system
over the IP network. HP recommends that you provide reliable network connections for cluster node
to HP 3PAR storage system communications.
SAN fabric considerations
Ensure that cluster nodes in the zoning configuration recognize their respective (local) HP 3PAR
storage system, but not the remote HP 3PAR storage system.
