HP 3PAR Cluster Extension Software Administrator Guide (5697-2047, June 2012)

4 User configuration file and HP 3PAR Cluster Extension
objects
Objects (also called properties in this document) define the HP 3PAR storage system environment
and failover/failback behavior. You can customize HP 3PAR Cluster Extension objects in the user
configuration file or in the cluster software.
User configuration file
For the CLI implementation of HP 3PAR Cluster Extension, the user configuration file UCF.cfg is
used to configure application service-specific information. UCF.cfg describes the dependencies
between application services and HP 3PAR Remote Copy volume groups in one file for all
application services in the cluster.
A UCF.cfg file is available in the HP 3PAR Cluster Extension sample directory. This file can be
copied and modified to suit a specific configuration.
• Windows: %ProgramFiles%\Hewlett-Packard\Cluster Extension 3PAR\sample
• Linux:/opt/hpclx3par/sample
After the user configuration file has been created, it must be copied to the /conf directory on all
cluster nodes.
• Windows: %ProgramFiles%\Hewlett-Packard\Cluster Extension 3PAR\conf
• Linux: /etc/opt/hpclx3par/conf
For more information, see “Sample configuration file” (page 72)and “Creating and configuring
the user configuration file” (page 75).
Windows Clustering
HP 3PAR Cluster Extension integration with Windows cluster does not require a user configuration
file when the standard environment for HP 3PAR Cluster Extension is used. The HP 3PAR Cluster
Extension objects that are integrated with Windows cluster can be configured as resource private
properties in the cluster software. See “Configuring HP 3PAR Cluster Extension for Windows”
(page 21)for more information.
RHCS, HP Serviceguard and SLE HA
HP 3PAR Cluster integration with RHCS and SLE HA uses a HP 3PAR Cluster Extension resource
configuration file. The objects and format in the configuration file are the same as the UCF.cfg
file.
File structure
The configuration file consists of a COMMON section and an APPLICATION section. These sections
are distinguished by control tags. HP 3PAR Cluster Extension uses the following objects as control
tags:
• COMMON
• APPLICATION
Objects have one of the following formats:
A definition of an object; for example, COMMON or APPLICATIONtag
A number; for example, a timeout valueinteger
