Keeping a separate location for coredumps allows you to have those logs if the host does not have local storage or if the host is an autodeploy host which does not have any boot storage either.įeel free to leave comments about your best PSOD you’ve experienced and (or) if you have setup an ESXi coredump to be able to investigate the problem.VCenter Server 6.5 | | ISO Build 4602587

Drivers for for those devices sometimes aren’t supported with latest vSphere releases and as such, either those might prevent to upgrade, or they upgrade and cause system instability, performance problems and in some extreme causes, PSODs. Quite often I’ve seen hosts going into PSOD because of unsupported hardware, such as NICs or storage add-on cards. We’ll use Putty SSH client for the job.Ĭonnect your ESXi host through Putty (make sure to enable SSH on your ESXi) and run this command below:Įxplore VSAN from StarWind StarWind VSAN White Paper Final WordsĪs I mentioned, PSOD does not happens often, but when doing upgrades/updates and you have dependencies, or VMware Installation Bundle (VIB) which is outdated, it might happen. Then we will need to configure each VMware ESXi host via a command line. When this is done, we need to instruct our ESXi hosts to send those core dumps to our VCSA. VMware ESXi Dump Collector – Start the service By default, this service, which starts manually, is in stopped state.

ESXi Dump Collector – How to setup?įirst thing first login to your vCenter Server appliance using web client and start the dump collector service. Please Note that ESXi Dump Collector is not supported to be configured on a VMkernel interface that is running on NSX-T N-VDS switch. If your environment is not new, you might first check whether the dump collector works correctly and that it has been sized appropriately.
You can take screenshot of PSOD as the screenshot itself tells you similar story that you’ll find within your core dumps. It is important to be able to troubleshoot the issue via those core dumps. It is quite rare, but it can happen from time to time, after an upgrade, with obsolete firmware/drivers combination etc. VMware ESXi is basically sending the state of the VMkernel Memory (also called core dumps) to a network server (if you have configured one) each time there is a PSOD. In our case we’ll use VMware vCSA as a storage location. You’ll need to configure ESXi Dump Collector by using ESXCLI commands and keep core dumps on a network server for use during debugging. In fact, not all ESXi installations are stateful, so for stateless installations, such as those where you’ll use VMware auto deploy, you’ll need an external space to store logs. You want to keep coredumps on a network location.You might run out of space on a local datastore.Why would you like to change the default location of coredump? The vSphere ESXi Dump Collector collects memory dumps over the network instead of trying to save it locally.
In this case, it is very important to have a possibility and recover the memory to somewhere else.ĭump collector is a support tool for VCSA and allows ESXi to save the VMkernel memory to a network server instead to a disk. There are times when VMware ESXi gets Purple screen of death (PSOD).
