4 User configuration file and P6000 Cluster
Extension objects
Objects (also called properties in this document) define the disk array environment and failover/failback
behavior. You can customize P6000 Cluster Extension objects in the user configuration file or in the
cluster software.
User configuration file
For the CLI implementation of P6000 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 P6000 Continuous Access DR groups in one file for all application services
in the cluster.
A UCF.cfg file is available in the P6000 Cluster Extension sample directory. This file can be copied
and modified to suit a specific configuration.
• Windows: %ProgramFiles%\Hewlett-Packard\Cluster Extension EVA\sample
• Linux: /opt/hpclxeva/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 EVA\conf
• Linux: /etc/opt/hpclxeva/conf
For more information, see “Sample configuration file” on page 85 and “Creating and configuring
the user configuration file” on page 89
MSCS
P6000 Cluster Extension integration with MSCS does not require a user configuration file when the
standard environment for P6000 Cluster Extension is used. The P6000 Cluster Extension objects that
are integrated with MSCS are can be configured as resource private properties in the cluster software.
See “Configuring EVA Cluster Extension for Windows” on page 25 for more information.
RHCS and SLE HA
P6000 Cluster integration with RHCS and SLE HA uses a P6000 Cluster Extension resource
configuration file. The objects and format in the configuration file are the same as the UCF.cfg file.
See “Configuring EVA Cluster Extension for Linux” on page 55 for more information.
File structure
The configuration file consists of a COMMON section and an APPLICATION section. These sections
are distinguished by control tags. P6000 Cluster Extension uses the following objects as control tags:
