Unable to shut down Ubuntu when the graceful
shutdown option from iDRAC is selected or when
power button is pressed on the server
Description
When you select the Graceful Shutdown option from any system management interface such as iDRAC
or press the power button, the system goes to a suspended state and all the tasks stop. Even the
firmware updates from iDRAC interface that requires restart, takes longer time to update, and the system
will be Hard reset upon iDRAC watchdog time expiration.
Workaround Change the power settings.
1. Go to Settings > Power.
2. In the Suspend and power button section, select Power Off from the When the Power Button is
pressed drop-down list.
NOTE: By default the Suspend option is selected.
NOTE: The workaround may not work when the system is locked. Gnome prevents accidental
shutdown when the system is locked. As a security precaution, Gnome does not allow any power
related actions such as shutdown from any system management interfaces like iDRAC or when
the power button is pressed unless the user is active and logged-in to OS.
Systems affected All Dell EMC PowerEdge servers
Applies to Ubuntu 18.04
