PSOD Info needed

Hi all,

I got a PSOD on a HP blade server. We could not capture the print screen. It is running esxi 4.1 U2.

In ESX the vmkernel dump will get generated in root folder. However as this is esxi there is no root folder.

I need to know if I did not capture the print screen of the PSOD >>> server was rebooted and the logs are gone now >>>> how do I verify why did the PSOD came up ??

Also what is the location of the PSOD dump file

Thanks in advance
