HP StorageWorks P9000 Cluster Extension Software Administrator Guide (TB534-96009, February 2011)

6 User configuration file and P9000 Cluster Extension
objects
Objects (also called properties in this document) define the disk array environment and
failover/failback behavior. Information comes directly from the cluster software, indirectly from the
disk array through RAID Manager, and from a configuration file created by users. This file describes
the dependencies between application services and RAID Manager device/copy groups in one
file for all application services in the cluster.
The user configuration file provides customized and default values for supported parameters. You
can specify all customizable P9000 Cluster Extension objects in the file, and a copy must exist on
all nodes using P9000 Cluster Extension. P9000 Cluster Extension uses the information objects to
match current disk states and configuration parameters and to invoke actions, including preparing
disks to be activated or stopping the application startup.
User configuration file location
The user configuration file is placed in the configuration directory:
Linux
/etc/opt/hpclx/conf
Windows
%ProgramFiles%\Hewlett-Packard\Cluster Extension XP\conf
For more information, see:
• “Basic configuration example” (page 92)
• “Creating and configuring the user configuration file” (page 71)
MSCS
P9000 Cluster Extension integration with MSCS does not require a user configuration file when
the standard environment for P9000 Cluster Extension is used. The P9000 Cluster Extension objects
that are integrated with MSCS can be configured as resource-specific properties in the cluster
software.
For more information, see “Configuring P9000 Cluster Extension resources” (page 27).
RHCS and SLE HA
P9000 Cluster Extension integration with RHCS and SLE HA uses a P9000Cluster Extension resource
configuration file. The objects and format in the configuration file are the same as the UCF.cfg
file.
For more information, see “Configuring P9000 Cluster Extension for Linux” (page 53).
File structure
The configuration file consists of a COMMON section and an APPLICATION section. These sections
are distinguished by control tags. P9000 Cluster Extension uses the following objects as control
tags:
• COMMON
• APPLICATION
