3 Installing XP Cluster Extension Software
for Windows
This chapter describes the installation of XP Cluster Extension in MSCS environments with HP XP disk
arrays.
This version of XP Cluster Extension allows you to install, uninstall, modify, and repair XP Cluster
Extension on all of the nodes in a cluster by running the installer from one node in the cluster. This
feature is not available for performing XP Cluster Extension upgrade procedures. When upgrading,
you must run the installation package separately on each cluster node.
NOTE:
For information on configuring XP Cluster Extension in an MSCS environment, see the HP StorageWorks
XP Cluster Extension Software Administrator Guide .
Prerequisites
Before installing XP Cluster Extension, perform the following tasks:
1. Check “General installation prerequisites” on page 8 to make sure your setup meets the general
installation prerequisites.
2. Install and configure the HP MPIO Full-Featured Device Specific Module (DSM) for XP Disk Arrays
(called the HP MPIO XP DSM in this guide) to enable alternative pathing for Windows.

failover, a feature that is not available with Windows operating systems.
HP MPIO XP DSM must be installed on the server cluster systems before you connect the server
to the second I/O path.
3. If you plan to use the XP Cluster Extension cluster-wide installation feature, verify that the WMI
service is running.
4. Prepare the data centers for XP Cluster Extension Software installation and configuration.
For more information, see “Pre-installation procedures” on page 18.
