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?
2 If powered on, is the operating system functioning, crashed, or just frozen?
3 If powered off, did the power turn off unexpectedly?
For crashed systems, check the last crash screen (see "Viewing the Last
System Crash Screen" on page 283), and use console redirection (see
"Supported Screen Resolutions Refresh Rates on the Managed System" on
page 162) and remote power management (see "Managing Power on a
Remote System" on page 277) 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.
