Understanding the Last Crash Tool in iDRAC
Server Troubleshooting (32%)
Explain Configuration Validation, crash capture, and minimum to POST

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
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
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
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
"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.
