Managing Serviceguard Sixteenth Edition, March 2009

VOLUME_GROUP The name of an LVM volume group whose disks
are attached to at least two nodes in the cluster.
Such disks are considered cluster-aware. The
volume group name can have up to 39 characters
(bytes).
Cluster Configuration: Next Step
When you are ready to configure the cluster, proceed to “Configuring the Cluster ”
(page 216). If you find it useful to record your configuration ahead of time, use the
worksheet in Appendix E.
Package Configuration Planning
Planning for packages involves assembling information about each group of highly
available services.
NOTE: As of Serviceguard A.11.18, there is a new and simpler way to configure
packages. This method allows you to build packages out of smaller modules, and
eliminates the separate package control script and the need to distribute it manually;
see Chapter 6: “Configuring Packages and Their Services ” (page 253) for complete
instructions.
This manual refers to packages produced by the newer method as modular packages,
and to packages produced by the older method as legacy packages.
The discussion that follows assumes you will be using the modular method. For
information and instructions on creating and maintaining older packages, see
“Configuring a Legacy Package” (page 338).
The document Framework for HP Serviceguard Toolkits provides a guide to integrating
an application with Serviceguard, and includes a suite of customizable scripts intended
for use with legacy packages. This document is included in the Serviceguard Developer’s
Toolbox, which you can download free of charge
fromhttp://www.hp.com/go/softwaredepot.
