======================= Disable Monitoring =======================
============================================================================
Hardware event monitoring watches the system for hardware problems. If
you shut this facility down, the system will no longer be able to alert
you to many hardware problems.
In addition, if ServiceGuard is configured to use hardware event monitoring
to determine the health of your system, then disabling monitoring may cause
it to consider this system as having failed. This will result in a package
failover. Type "h" for help to find out more about the implications of
shutdown on ServiceGuard.
Furthermore, if you have used the Event Monitoring Service (EMS) Graphical
User Interface (GUI) within the System Administration Manager (SAM) to
configure the event monitors, this configuration will not be saved, and no
actual monitoring will take place until hardware event monitoring is
re-enabled and you add the monitoring requests back again using the EMS
GUI. Event monitoring resources show up in the EMS GUI under the resource
class "status".
Are you sure you wish to disable event monitoring?
