Configuring the Legacy Package Control
Script and RAID Configuration File
This section describes the package control scripts and configuration files
that you need to create and edit to enable Software RAID in your
Serviceguard environment.
IMPORTANT Serviceguard A.11.18 supports a new process for configuring packages.
This manual refers to packages created by this method as modular
packages, and assumes that you will use it to create new packages; it is
simpler and more efficient than the older method, allowing you to build
packages from smaller modules, and eliminating the separate package
control script and the need to distribute it manually. For more
information on modular packages, see“Configuring Modular Packages for
Extended Distance Cluster Software” on page 88.
Packages created using Serviceguard A.11.17 or earlier are referred to as
legacy packages.
Earlier versions of Serviceguard supported MD as a multipathing
software. As a result, the package control script includes certain
configuration parameters that are specific to MD. Do not use these
parameters to configure XDC in your environment. Following are the
parameters in the configuration file that you must not edit:
# MD (RAID) CONFIGURATION FILE
# Specify the configuration file that will be used to define
# the md raid devices for this package.
# NOTE: The multipath mechanisms that are supported for shared storage
# depend on the storage subsystem and the HBA driver in the
# configuration. Follow the documentation for those devices when setting
# up multipath. The MD driver was used with earlier versions of
# Serviceguard and may still be used by some storage system/HBA
# combinations. For that reason there are references to MD in the template
# files, worksheets, and other areas. Only use MD if your storage systems
