Managing HP Serviceguard A.11.20.20 for Linux, March 2014

Table 14 Types of Changes to Packages (continued)
Required Package StateChange to the Package
Both packages can be either running or halted.
Special rules apply to packages in maintenance mode; see “Dependency Rules
for a Package in Maintenance Mode or Partial-Startup Maintenance Mode ”
(page 223).
For dependency purposes, a package being reconfigured is considered to be
UP. This means that if pkgA depends on pkgB, and pkgA is down and pkgB is
being reconfigured, pkgA will run if it becomes eligible to do so, even if pkgB's
reconfiguration is not yet complete.
HP recommends that you separate package dependency changes from changes
that affect resources and services that the newly dependent package will also
depend on; reconfigure the resources and services first and apply the changes,
then configure the package dependency.
For more information see “About Package Dependencies” (page 113).
Add or delete a configured
dependency
Package can be running provided the status of the generic resource is not 'down'.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 112).
Add a generic resource of
evaluation type
during_package_start
Package can be running if the status of generic resource is 'up', else package
must be halted.
Add a generic resource of
evaluation type
before_package_start
Package can be running.Remove a generic resource
Package can be running if the status of generic resource is 'up'.
Not allowed if changing the generic_resource_evaluation_type causes the package
to fail.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 112).
Change the
generic_resource_evaluation_type
Package can be running for resources of evaluation type before_package_start
or during_package_start provided the new up criteria does not cause the resource
status to evaluate to 'down'.
Not allowed if changing the generic_resource_up_criteria causes the package to
fail.
For information on online changes to generic resources, see “Online
Reconfiguration of Generic Resources” (page 112).
Change the
generic_resource_up_criteria
Package can be running. See “Online Reconfiguration of serviceguard-xdc
Modular Package Parameters” (page 112).
Change modular serviceguard-xdc
package parameters:
xdc/xdc/rpo_target
xdc/xdc/raid_monitor_interval
xdc/xdc/raid_device
xdc/xdc/device_0
xdc/xdc/device_1
Package can be running.
NOTE: Do not include the email module in the modular package. The
serviceguard-xdc and toolkit packages automatically includes the email module
in the modular package.
Add, change, or delete an email
attribute
NOTE: Consider a configuration in which the volume group and the corresponding filesystem
are present in two different packages. To perform online reconfiguration of such packages, the
package with the volume group must be reconfigured before you reconfigure the filesystem package.
HP recommends that you do not perform online reconfiguration for both these packages in a single
command as it might cause one or more packages to fail.
