HP 3PAR StoreServ Cluster Extension Software Administrator Guide

Figure 5 Failover cluster manager window
3PAR StoreServ Cluster Extension supports CSV disk on Windows Server 2012/2012 R2 in
addition to non CSV disk support. Configuration of CSV disk for CLX is similar to configuration of
normal disk for CLX support. Since the CSV role is hidden and not seen in Failover Cluster GUI,
CLX has provided PowerShell Cmdlets to configure Cluster Extension 3PAR resource for the CSV
disk. See “Cluster Extension Cmdlets for CSV and Virtual Machine Management” (page 69) on
how to configure CSV disk for CLX.
Configuration tool (clx3PARconfig.exe)
HP 3PAR StoreServ Cluster Extension uses the configuration tool(clx3PARconfig.exe) to store
configuration and access information for each configured management server. This tool stores
information in the clx3parcfg file. However, because the clx3parcfg file cannot be edited
with a standard text editor, management server entries can only be added, modified, and deleted
using the configuration tool that is included with the standard installation of HP 3PAR StoreServ
Cluster Extension.
HP 3PAR Management Console or HP 3PAR CLI
HP 3PAR Management Console or HP 3PAR CLI is used to create virtual volumes and configure
the HP 3PAR StoreServ Storage.
IP network considerations
HP 3PAR CLI is essential to Cluster Extension which communicates with the HP 3PAR StoreServ
Storage over the IP network. HP recommends that you provide reliable network connections for
cluster node to HP 3PAR StoreServ Storage communications.
