Managing Serviceguard Eighteenth Edition, September 2010

Table 7-3 Types of Changes to Packages (continued)
Required Package StateChange to the Package
Package can be running.
Serviceguard will not allow the change if it would cause the package
to fail. In addition, Serviceguard will reject the change if the resource
is not UP within about 30 seconds. Multiple changes that take longer
than this should be done incrementally; resources that are very slow to
come up may need to be configured offline.
Serviceguard treats a change to resource_name as deleting the existing
resource and adding a new one, meaning that the existing resource is
stopped.
Add or remove a resource:
modular package
Package can be running.
Serviceguard will not allow a change to resource_up_value if it would
cause the package to fail.
Change
resource_polling_interval,
resource_start, resource_up_value:

For AUTOMATIC resources, package can be running. See the entry for
“Add or remove a resource: modular package” for more information.
For DEFERRED resources, package must not be running.
Add or remove a resource:
legacy package
For AUTOMATIC resources, package can be running.
For DEFERRED resources, package must not be running.
Serviceguard will not allow a change to RESOURCE_UP_VALUE if it
would cause the package to fail.

(Remember that a volume group must already be configured into the
cluster, via the VOLUME_GROUP parameter, before you can configure
it into to a package.)
Add a volume group: modular
package
Package must not be running.Add a volume group: legacy
package
Package should not be running.
CAUTION: Removing a volume group may cause problems if file
systems, applications or other resources are using it. In particular, if the
volume group cannot be deactivated and
kill_processes_accessing_raw_devices is set to yes, processes accessing the
volume group as a raw device will be killed; in addition the CAUTION
under “Remove a file system: modular package” applies to any file systems
using the volume group.
