them, and then start them up on another node selected from the package’s
configuration list; see node_name (page 197).
To generate a package configuration file that creates a failover package, include-m
sg/failover on the cmmakepkg command line. See “Generating the Package
Configuration File” (page 214).
• Multi-node packages. These packages run simultaneously on more than one node
in the cluster. Failures of package components such as applications, services, or
subnets, will cause the package to be halted only on the node on which the failure
occurred.
Relocatable IP addresses cannot be assigned to multi-node packages.
IMPORTANT: Multi-node packages must either use a clustered file system such
as Red Hat GFS, or not use shared storage.
To generate a package configuration file that creates a multi-node package,
include-m sg/multi_node on the cmmakepkg command line. See “Generating
the Package Configuration File” (page 214).
• System multi-node packages. System multi-node packages are supported only
for applications supplied by HP.
NOTE: The following parameters cannot be configured for multi-node packages:
• failover_policy
• failback_policy
• ip_subnet
• ip_address
Volume groups configured for packages of this type must be activated in shared mode.
For more information about types of packages and how they work, see “How the
Package Manager Works” (page 49). For information on planning a package, see
“Package Configuration Planning ” (page 118).
When you have decided on the type of package you want to create, the next step is to
decide what additional package-configuration modules you need to include; see
“Package Modules and Parameters” (page 191).
Package Modules and Parameters
The table that follows shows the package modules and the configuration parameters
each module includes. Read this section in conjunction with the discussion under
“Package Configuration Planning ” (page 118).
Use this information, and the parameter explanations that follow (page 196) to decide
which modules (if any) you need to add to the failover, multi-node, or system multi-node
module, to create your package. If you are used to creating legacy packages, you will
