HP 3PAR StoreServ Cluster Extension Software Administrator Guide (5697-2442, July 2013)

3PAR StoreServ Cluster Extension supports CSV disk on Windows Server 2012 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 60) 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.
SAN fabric considerations
Ensure that cluster nodes in the zoning configuration recognize their respective (local) HP 3PAR
StoreServ Storage, but not the remote HP 3PAR StoreServ Storage.
