Table 7-2 Types of Changes to Packages (continued)
Required Package StateChange to the 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.
Change
RESOURCE_POLLING_INTERVAL
RESOURCE_UP_VALUE: legacy

Package must not be running.Change RESOURCE_START:
legacy package
Package can be running.Add a volume group: modular

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.
Remove a volume group:
modular package
Package must not be running.Remove a volume group: legacy
package
Package should not be running (unless you are only changing
fs_umount_opt).
Changing file-system options other than fs_umount_opt may cause
problems because the file system must be unmounted (using the existing
fs_umount_opt) and remounted with the new options; the CAUTION
under “Remove a file system: modular package” applies in this case as
well.
If only fs_umount_opt is being changed, the file system will not be
unmounted; the new option will take effect when the package is halted
or the file system is unmounted for some other reason.
