HP 3PAR Cluster Extension Software Installation Guide for Windows (5697-1822, March 2012)

Complete the following procedure to make each disk accessible to the nodes in the remote data
center:
• On the source side (local data center), create the volume groups, logical volumes, and file
systems that will be used with the Linux clusters.
• Use HP 3PAR Inform CLI to switch the replication mode of the destination side volume groups
to source. This allows nodes in the remote data center to access the shared disks with
read/write access.
• Create mount points on each node in the remote data center, and then use vgscan to import
volume groups and logical volumes.
NOTE: For more information about using LVM, see your Linux cluster software documentation.
Installing and configuring the cluster software
Install and configure the cluster software for your Linux operating system. See the SLE HA and
RHCS documentation for detailed installation procedures.
NOTE: A properly configured and fully functioning cluster solution is a prerequisite for the HP
3PAR Cluster Extension Software.
Installing HP 3PAR Cluster Extension Software for Linux
Cluster Extension Software provides an installation script for Linux. This script installs the software
with SLE HA or RHCS.
Use this procedure to install the following components:
• SLE HA and RHCS integration executable (clx3PARlxcs).
• CLI (clx3PARrun)
To install the software:
1. Log in as root.
2. Download the Cluster Extension Software installer.
a. Browse to http://www.hp.com/go/softwaredepot.
b. Click Storage and NAS in the product category list.
c. Follow the on-screen instructions to download the installer.
3. Uncompress and extract the contents of this downloaded file to the hpclx3PAR_version
directory (created during extraction) by entering the following command:
# tar xvfz downloaded_file
4. Enter cd hpclx3PAR_version to change to the hpclx3PAR_version directory.
5. Enter ./INSTALL to run the installation script.
6. The installer prompts you to install a permanent license key. Do one of the following:
• If you already have a permanent license key, click Yes. Follow the instructions in
“Licensing” (page 27) to retrieve and install the license key.
NOTE: You must perform the permanent license key installation procedure separately
on each cluster node.
• If you do not yet have a permanent license key, click No. An instant-on license key that
is valid for 60 days will be installed. When you are ready to install the permanent license
key, follow the instructions in “Licensing” (page 27).
