about what went wrong. There is a VMware KB Article 1005184 concerning this issue, and it has been updated significantly intel machine check exception decoder since I have started to take interest in these errors. UPDATE: I have published a new CPU Stress Test & Machine Check Error debugging article - check it out if machine check exception error you'd like to learn more. If you are "lucky", you can see and decode yourself what preceded the crash. This is because both AMD and Intel CPUs have implemented something by the name of Memory Check Architecture. This architecture enables the CPUs to intelligently determine a fault that happens anywhere on the data transfer path during processor operation. This

can capture Memory operation errors, CPU Bus interconnect errors, cache errors, and much more. How to determine what has been causing your system to fail? Read on. You will need to browse to Intel's website hosting the Intel® 64 and IA-32 Architectures Software Developer Manuals. There, download a manual named "Intel 64 and IA-32 Architectures Software Developer's Manual Combined Volumes 3A, 3B, and 3C: System Programming Guide". I highly recommend printing it, because you will be doing some back-and-forth seeking. Now, to get list of possible Machine Check Errors captured by the VMkernel, run the following in your SSH session with superuser privileges: cd /var/log;grep MCE vmkernel.log this will output something similar to this: Most of the times, the VMkernel decodes these messages for you - on this image you see that there are plenty of Memory Controller Read Errors. You can see more closely where the problem originates from: CMCI: This stands for Corrected Machine Check Interrupt - an error was captured but it was corrected and the VMkernel can keep on running.

Machine Check Exception Windows 10
on an ESXi Host Nathan Simon Profile: Nathan Simon So your ESXi host is stuck at a PSOD or the “Purple Screen of Death”, what do you do? Well one would figure its hardware, but it https://vmxp.wordpress.com/2014/10/27/debugging-machine-check-errors-mces/comment-page-1/ also could be software related. Well I am going to tell you how to download and review the error logs. Mind you the way I am going to explain it is if the host can boot up and be connected to either vCenter or VI Client. I will also show you a command you can run from the service console if you just want the support logs to send to VMware. Onto http://itknowledgeexchange.techtarget.com/information-technology/how-to-troubleshoot-a-purple-screen-of-death-on-an-esxi-host/ the Information. First you want to have the host back up and running, it could be unstable at the moment, but you should have enough time to pull the support logs. Highlight the host in question. Click on File (top left of the VI Client), then click on “Export” then “Export System Logs” Your next screen will allow you to select the system logs you would like to export, I just select them all. Once you click next you can select where you want to export them to. Click next to start the export. Use a program like 7-Zip to extract the newly created file to a temporary location, once it is extracted you need to extract again, I know, they doubled up the compression, more so to keep the normal folk out! 🙂 Once everything is extracted you should see the following folders. The most important one is the "Core" folder which contains the kernel dump, the PSOD will purge what was in memory to a file called vmkernel-zdump.1 or something to that affect and place it in that directory. You will have to use something like NotePad++ to open the vmkernel-zdump file, once you do, you can pretty much search for “error” or “fail” or “panic” and you should find your issue. In my example,
know (at least I hope so) what HA is responsible for within a vSphere Cluster. Although it is great that vSphere HA responds to a failure of a host / VM / application and even in some cases your storage device; wouldn't it be http://www.yellow-bricks.com/2013/10/04/ha-futures-pro-active-response/ nice if vSphere HA could pro-actively respond to conditions which might lead to http://mce.memory.controller.error.errorwiki.org/ a failure? That is what we want to discuss in this article. What we are exploring right now is the ability for HA to avoid unplanned downtime. HA would detect specific (health) conditions that could lead to catastrophic failures and pro-actively move virtual machines of that host. You could for instance think of a situation machine check where 1 out of 2 storage paths goes down. Although not directly impacting the machines from an availability perspective, it could be catastrophic if that second path goes down. So in order to avoid ending up in this situation vSphere HA would vMotion all the virtual machines to a host which does not have a failure. This could of course also apply to other components like networking or machine check exception even memory or CPU. You could potentially have a memory dimm which is reporting specific issues that could impact availability, this in its turn could then trigger HA to pro-actively move all potentially impacted VMs to a different host. A couple of questions we have for you: When such partial host failures occur today, how do you address these conditions? When do you bring the host back online? What level of integration do you expect with management tools? In other words, should we expose an API that your management solution can consume, or do you prefer this to be a stand-alone solution using a CIM provider for instance? Should HA treat all health conditions the same? I.e., always evacuate all VMs from an "unhealthy" host? How would you like HA to compare two conditions? E.g., H1 fan failure, H2 network path failure?

DRS does wonders, but this could definitely help. So here we go: 1. When a partial failure occurs, I see the alert via e-mail or vCenter
