4 Planning and Documenting an
HA Cluster
Building an Serviceguard cluster begins with a planning phase in which
you gather and record information about all the hardware and software
components of the configuration. Planning starts with a simple list of
hardware and network components. As the installation and
configuration continue, the list is extended and refined. After hardware
installation, you can use the graphical user interface, Serviceguard
Manager, or a variety of HP-UX commands to obtain information about
your configuration; this information is entered on the worksheets
provided in this chapter. During the creation of the cluster, the planning
worksheets provide the values that are input with Serviceguard
Manager or edited into the ASCII configuration files and control scripts.
With Serviceguard version 11.16, the SAM high availability tool is no
longer available. Configuration of Serviceguard clusters with version
11.16 or later is now done through Serviceguard Manager version
A.04.00 or later. Administration of Serviceguard clusters with version
11.12 or later is now done with Serviceguard Manager version 11.12 or
later. For more information about Serviceguard Manager, see Chapter 7.
For information about using SAM on older versions, see earlier editions
of this manual.
When the configuration is finished, you can use Serviceguard Manager to
capture all the configuration data in a.sgm file. Later, you can see the
information in Serviceguard Manager. Clusters and packages that are
configured in Serviceguard Manager can be modified in Serviceguard
Manager. Refer to the section “Using Serviceguard Manager” in Chapter
7.
