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.
