4 Planning and Documenting an
HA Cluster
Building a 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; enter this information in the blank sheets in
Appendix F, “Blank Planning Worksheets” on page 443. (This chapter
has example worksheets.) 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.
Starting with Serviceguard version A.11.16, the SAM High Availability
tool is no longer available.
Instead, configuration of Serviceguard clusters with version A.11.16 or
later can now be done through the Serviceguard Manager interface, with
version A.04.00 or later.
Also, administration of Serviceguard clusters with version A.11.12 or
later can also now be done with Serviceguard Manager.
For more information about Serviceguard Manager, see Chapter 7. For
information about using SAM on older versions of Serviceguard, 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.
