Managing Serviceguard 14th Edition, June 2007

Configuring Packages and Their Services
Choosing Package Modules
Chapter 6286
This parameter can be set for failover packages only. If this package will
depend on another package or vice versa, see also “About Package
Dependencies” on page 171.
failback_policy Specifies whether or not Serviceguard will
automatically move a package that is not running on its primary node
(the first node on its node_name list) when the primary node is once
again available. Can be set to automatic or manual. The default is
manual.
• manual means the package will continue to run on the current node.
• automatic means Serviceguard will move the package to the
primary node as soon as that node becomes available, unless doing so
would also force a package with a higher priority (see page 286) to
move.
This parameter can be set for failover packages only. If this package will
depend on another package or vice versa, see also “About Package
Dependencies” on page 171.
priority Assigns a priority to a failover package whose
failover_policy (see page 285) is configured_node. Valid values are
1 through 3000, or no_priority. The default is no_priority. See also
the dependency_ parameter descriptions, starting on page 286.
priority can be used to satisfy dependencies when a package starts, or
needs to fail over or fail back: a package with a higher priority than the
packages it depends on can force those packages to start or restart on the
node it chooses, so that its dependencies are met.
If you assign a priority, it must be unique in this cluster. A lower number
indicates a higher priority, and a numerical priority is higher than
no_priority. HP recommends assigning values in increments of 20 so
as to leave gaps in the sequence; otherwise you may have to shuffle all
the existing priorities when assigning priority to a new package.
New A.11.18 (for both modular and legacy packages). See “About
Package Dependencies” on page 171 for more information.
dependency_name A unique identifier for a particular dependency that
must be met in order for this package to run (or keep running). The
length and formal restrictions for the name are the same as for
package_name (see page 282).
