Table 20-12. Power Control Actions
Power On
System
Turns on the system power (equivalent to pressing the power button
when the system power is off).
Power Off
System
Turns off the system power (equivalent to pressing the power button
when the system power is on).
NMI
(Non-Masking
Interrupt)
Sends a high-level interrupt to the operating system, which causes
the system to halt operation to allow for critical diagnostic or
troubleshooting activities.
Graceful
Shutdown
Attempts to cleanly shut down the operating system, then powers off
the system. It requires an ACPI (Advanced Configuration and Power
Interface) aware operating system, which allows for system directed
power management.
NOTE: A graceful shutdown of the server operating system may not be
possible when the server software stops responding, or if you are not
logged as an administrator at a local Windows console. In these cases,
you must specify a forced reboot instead of a graceful shutdown of
Windows. In addition, depending on the version of the Windows OS,
there might be a policy configured around the shutdown process that
modifies shutdown behavior when triggered from iDRAC6. See
Microsoft’s documentation for the local computer policy “Shutdown:
Allow system to be shut down without having to login.”
Reset System
(warm boot)
Reboots the system without powering off (warm boot).
Power Cycle
System (cold
boot)
Powers off, then reboots the system (cold boot).
