HP P6000 Cluster Extension Software Administrator Guide (5697-2274, November 2012)

3 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 in the
%ProgramFiles%\Hewlett-Packard\Cluster Extension EVA\sample location. This
file can be copied and modified to suit a specific configuration.
After the user configuration file has been created, it must be copied to the /conf directory on all
cluster nodes. The /conf directory is located at %ProgramFiles%\Hewlett-Packard\Cluster
Extension EVA.
For more information, see “Sample configuration file” (page 51) and Creating and configuring
the user configuration file (page 55)
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 (page 16) 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:
• 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
A name, which can include alphabetic and numeric characters and underscores; for example, an
application startup value
string
A list of space-separated strings, for example, a list of host names (lists of numbers are stored as lists
of strings)
list
Text that is a comment starts with the pound (#) symbol and continues until the end of the line.
Comments can start on a new line or be part of a line specifying an object.
Specifying object values
You do not need to change the default settings unless you want to change the degree of protection
for your DR group members. If you change an object, you may need to change additional objects
