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
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.
Change a file system: modular
package
Package can be running.
During the package reconfiguration, if the fsck command on a file system fails,
the package does not start.
CAUTION: To avoid this issue, run the fsck command on the file system outside
the package, and then add the file system to the modular package.
Add a file system: modular package
Package must not be running.Add or change a file system: legacy
package
Package can be running.
CAUTION: Removing a file system may cause problems if the file system cannot
be unmounted because it's in use by a running process. In this case Serviceguard
kills the process; and keeps the package running with errors. For more information,
see “Handling Failures During Online Package Reconfiguration” (page 248).

These changes in themselves will not cause any file system to be unmounted.

Changes take effect when applied, whether or not the package is running. If you
add a script, Serviceguard validates it and then (if there are no errors) runs it
when you apply the change. If you delete a script, Serviceguard stops it when
you apply the change.
