Receiving this kind of information in the middle of the night should be the biggest thing for all system administrators.

First of all, I quickly went through iDRAC and found that the server had been restarted and got the relevant log information.

Through the official explanation of Dell, it is determined that the problem is caused by an exception at the OS level. Open Windows Event Log and filter using time & severity, and we find the following information:

Therefore, I guess this accident is caused by a blue screen error of 0x7a type! In order to confirm this conjecture and continue to analyze the root cause, the DUMP file is analyzed with the help of the Debug tool provided by Microsoft, as follows:

Through the preliminary bugcheck, basically confirmed my guess, and then combined with call stack information

We can judge that it is caused by the removal of a partition, and then conduct a depth analysis to determine which partition was removed and why it was removed.

Get the following two important pieces of information:

1 、 Corruption may occur in VolumeId: C:

2. Error value: C000000E, disk type: 0

In order to determine that disk C has an error with a status code of 0xC000000E, which leads to this event!

Combined with the status code description provided by Microsoft

It can be clearly judged that it is due to hardware and driver problems (why there is no related error report in iDRAC? )

Finally, the case is submitted to Dell, and it is recommended to upgrade the raid card and disk controller, hoping to solve this problem completely!

Two related topics

1. You can use the Chkdsk command to check the system partition, specifically the command Chkdsk / f / r c:

2. Viruses can also cause blue screens. In addition to antivirus software, we can also analyze the startup location of Local Security Authority Process=lsass.exe. Normally, it is started by C:\ Windows\ System32.
