Gather information from a PSOD on ESX 3.5

If you have a PSOD on ESX, you can get quite some information out of the PSOD screen.  Most of the times however, the server has been rebooted and the PSOD is gone.

The PSOD dump is stored in the /root directory.

cd /root

Run the following command to extract the log from the PSOD dump

vmkdump -l <dump_file>

A new file vmkernel-log.1 will be created in the same directory.  You will see the contents of the PSOD and the actions that happened right before it towards the end of this logfile.

 

You can find more information in this slidedeck from VMworld 2006.  It’s rather old, but most of it is still valid for vSphere!
