ESXi v5.1 purple debug screen after hard disk fail

I have a Dell 2950 running ESXi v5.1  I had a few VM's running on it and then all of the sudden they all stopped responding.  I looked at the server and saw HDD1 had an error and a purple screen on the ESXi console.  I'm using ESXi v5.1 to boot via a USB memory stick via hard disk emulation mode.  Why would a failed array member cause this?  When rebooting the server it came back up with a failed member being noted..  But.. The drive is green.. I'll figure the failed drive part out.. But..  Any ideas to ESXi going to a purple screen like this?  Also, the ESXi server is running vCenter with VSA Manager on it.

We have seen PSOD (Purple Screen of Deaths) occur, when a disk has failed in RAID sets on ESXi.

I would check that all firmwares are up to date on the Dell server.

Again this can be tested, by pulling a disk out of the RAID set, whilst server is running.

Could it be due to the swap space residing on the physical drives.

We'll test that some more..  All firmware's are up to date..  Will double check  That's exactly what happened.

if you want to know the details in ESXi look for a dump file in esx host and check the log

 # ls  /var/core/

something like this file "vmkernel-zdump-????"

use this command to extract

# vmkdump -l
