							Recovering and Troubleshooting the Managed System263
Recovering and Troubleshooting the 
Managed System
This section explains how to perform tasks related to recovering and 
troubleshooting a crashed remote system using the DRAC 5 Web-based interface.
 First Steps to Troubleshoot a Remote System
 Managing Power on a Remote System
 Using the System Event Log (SEL)
 Viewing the Last System Crash Screen
First Steps to Troubleshoot a Remote System
The following questions are commonly used to troubleshoot high-level 
problems in the managed system:
1
Is the system powered on or off?
2If powered on, is the operating system functioning, crashed, or just frozen?
3If powered off, did the power turn off unexpectedly?
For crashed systems, check the last crash screen (see Viewing the Last 
System Crash Screen), and use console redirection (see Supported Screen 
Resolutions Refresh Rates on the Managed System) and remote power 
management (see Managing Power on a Remote System) to restart the 
system and watch the reboot process.
Managing Power on a Remote System
The DRAC 5 enables you to remotely perform several power management 
actions on the managed system so you can recover after a system crash or 
other system event. 
Use the Power Management page to do the following:
 Perform an orderly shutdown through the operating system when 
rebooting, and power the system on or off. 
 View the system’s current 
Power Status—either ON or OFF. 
						

							264Recovering and Troubleshooting the Managed System
To access the Power Management page from the System tree, click System 
and then click the Power Management tab.
 NOTE: You must have Execute Server Action Commands permission to perform 
power management actions. 
Selecting Power Control Actions from the DRAC 5 GUI
1Select one of the following 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). 

Reset System— Resets the system (equivalent to pressing the reset 
button); the power is not turned off by using this function. 

Power Cycle System— Power off, then reboot (cold boot) the system.
2Click Apply to perform the power management action (for example, cause 
the system to power cycle).
3Click the appropriate Power Management page button to continue 
(see
Table 15-1).
Selecting Power Control Actions from the DRAC 5 CLI
Use the racadm serveraction command to perform power 
management operations on the host system. 
racadm serveraction <
action>
The options for the  string are:
powerdown — Powers down the managed system.

powerup — Powers up the managed system.

							Recovering and Troubleshooting the Managed System265
powercycle — Issues a power-cycle operation on the managed system. This 
action is similar to pressing the power button on the system’s front panel 
to power down and then power up the system.

powerstatus — Displays the current power status of the server (ON, or 
OFF)

hardreset — Performs a reset (reboot) operation on the managed system.
