What is the Last Crash Tool in iDRAC?

Last Crash Screen: A feature in iDRAC that captures the last crash screen output from the operating system before a system crash or unexpected reboot.

Purpose: Provides valuable information for diagnosing the cause of a system crash, aiding in troubleshooting efforts.

Operating System Support

The Last Crash Screen feature is dependent on the operating system's ability to output crash information to the VGA console, which iDRAC can then capture.

Explanation of Options

Option A: MS Windows

Explanation: While Windows systems do produce crash screens (Blue Screen of Death), capturing this screen via iDRAC requires specific configurations and may not be fully supported.

Conclusion: Less likely to be the correct answer.

Option B: ESXi

Explanation: VMware ESXi can produce Purple Screen of Death (PSOD), but capturing this via iDRAC's Last Crash Screen feature is not typically supported without additional configuration.

Conclusion: Less likely to be the correct answer.

Option C: SUSE Linux

Explanation: SUSE Linux supports kernel crash dumps and can output crash information to the console, which iDRAC can capture using the Last Crash Screen feature.

Conclusion: Correct Answer.

Option D: Unix

Explanation: "Unix" is a broad term encompassing various operating systems. Without specifying, it's unclear which Unix variant is being referred to, and support may vary.

Conclusion: Less specific; not the best answer.

Explain Configuration Validation, crash capture, and minimum to POST: Emphasizes the importance of understanding features like the Last Crash Screen for troubleshooting.

System Administration (18%)

Verify health status and iDRAC license: Ensuring that the necessary features are enabled and supported on the operating system in use.

Conclusion

SUSE Linux supports the Last Crash Screen tool in iDRAC, allowing for the capture and analysis of crash information directly from the server's console output.

 Launch the Simulator:

Open the PowerEdge iDRAC simulator to access the user interface and perform the required task.

 Navigate to System Information:

In the top menu bar, select the "Configuration" tab.

From the options that appear, choose "Storage". This section will display details and configurations for the storage controllers installed on the server.

 Check the H965i Storage Controller:

Locate the H965i storage controller in the list. Selecting it should bring up a summary page with various specifications for the controller.

Look for the field labeled "Cache Memory Size". This will provide the cache memory size value for the controller.

To change the Power Supply Unit (PSU) configuration to a 2+0 setup with PSU2 as the primary in the iDRAC interface, follow these steps:

Step-by-Step Guide:

Navigate to Power Management Settings:

In the iDRAC interface, go to the Configuration tab at the top.

Select Power Management from the dropdown options.

Locate the Power Configuration Section:

Within the Power Management settings, look for a section labeled Power Configuration or Power Supply Configuration.

Select the Redundancy Policy:

Change the Redundancy Policy to 2+0. In this configuration, there will be no redundancy, and both power supplies will be active but configured as independent power sources without failover.

Set PSU2 as the Primary PSU:

Locate the option to designate the Primary PSU. Select PSU2 as the primary power source.

This setting ensures that PSU2 will handle the primary power load under normal conditions.

Apply and Save Changes:

Once you have made these changes, click Apply or Save to confirm the new configuration.

The interface may prompt for confirmation, after which the settings will be saved, and PSU2 will become the primary power supply under a 2+0 configuration.

Verify Configuration:

Review the updated settings to confirm that PSU2 is now set as primary and that the redundancy policy is 2+0, meaning only PSU2 is actively providing power without a secondary backup.

By following these steps in the iDRAC simulator, you will set up PSU2 as the primary power source with no redundancy, ensuring a 2+0 configuration. This setup will leverage PSU2 exclusively without automatic failover to another power supply.
