Restoring a controller team
NOTE:
Before running this script, re-install the controller. Otherwise an Error 404 condition
results and the controller is not restored. See
“Restoring a controller from a backup ” (page 137)
Because the scripts in this appendix cross page boundaries, be careful to avoid including the
page number when copying a script. Copying a script one page at a time can prevent inclusion
of page numbers.
