HP StorageWorks XP Cluster Extension Software Administrator Guide (T1656-96035, April 2010)

RHCS and SLE HA
XP Cluster Extension integration with RHCS and SLE HA uses an XP Cluster Extension resource
configuration file. The objects and format in the configuration file are the same as the UCF.cfg file.
For more information, see Chapter 5 on page 93.
VERITAS Cluster Server
Integrating XP Cluster Extension with VERITAS Cluster Server does not require a user configuration
file when the standard environment for XP Cluster Extension is used. The XP Cluster Extension objects
that are integrated with VERITAS Cluster Server are configurable as resource attributes in the cluster
software.
For more information, see Chapter 4 on page 75.
File structure
The configuration file consists of a COMMON section and an APPLICATION section. These sections
are distinguished by control tags. XP 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
When using the default configuration, you must provide values for the following objects:
• DeviceGroup: An XP RAID Manager device group
• DC_A_Hosts: A list of the cluster nodes in data center A
• DC_B_Hosts: A list of the cluster nodes in data center B
• RaidManagerInstances: A list of XP RAID Manager instances that XP Cluster Extension can use to
communicate with the disk array
• XPSerialNumbers: The serial numbers of the primary and secondary XP disk arrays
You do not need to change the default settings unless you want to change the degree of protection
for your paired disks. If you change an object, you may need to change additional related objects.
For example, if you change the FenceLevel object to DATA, you might need to change the
DataLoseMirror object.
