2. Open the Rename Surveillance Schedule dialog box (Figure 5-4) by performing one of the
following tasks:
• Click the Rename button in the Schedules panel
This only changes the names of the schedule and its disk file. The schedule is not saved
to disk.
• Choose File >Save Selected Schedule As
This changes the schedule and file names, and saves the schedule to the disk.

3. Edit the name in the input field. Valid characters are alphanumeric and underscore; the first
must be alphanumeric. Schedule names are case-sensitive. If you include invalid characters,
you will be prompted to replace them with underscores.
4. Click OK to change the name. Click Cancel to leave the name unchanged.
Deleting a Surveillance Schedule
This section describes about how to delete a surveillance schedule.
NOTE: You cannot delete any predefined schedule, distributed with HP-UX HIDS. For more
information, see “Predefined Surveillance Schedules and Groups” (page 80).
To delete a surveillance schedule, follow the steps:
1. On the Schedule Manager screen select a schedule in the Schedules panel.
2. Click the Delete button in the Schedules panel. This displays the Confirm Deletion dialog
box.
Click Yes to delete the schedule, and No to retain the schedule.
Undoing and Redoing Changes
The Undo and Redo buttons allow you to navigate among the changes you have made to
schedules, groups, or template properties. Undo backs up through a list of your recent changes.
Redo reverses the Undo, moving forward through the undone changes. The buttons are disabled
when you reach the end of the changes list.
NOTE: When you click Undo or Redo, the template highlight bar is moved to the top of the
list. If you switch to the Timetable tab, the change list is cleared and the buttons are disabled
out when you return to the Configure tab.
Saving a Surveillance Schedule
After a surveillance schedule has been created or modified, it is a good idea to save it to disk.
This provides security against system failures. If you do not save it manually, it is saved
automatically when you exit from the System Manager screen.
To save a surveillance schedule, follow the steps:
1. On the Schedule Manager screen select the schedule in the Schedules panel.
