I've been having an issue where one of our esxi hosts freezes during a power outage even though it's connected to a battery backup. Its a Dell R715. Dell and VMWare can't find a reason why. When it locks up the power is still on, fans are running and the HDD lights are still on (just not blinking since it doesn't have activity).
I am unable to ping it, SSH into it and our vcenter gives me an alert that it's down (and vmotions whatever servers are on it to another host).
Even though ive created a scratch partition VMWare says its not enough and they don't see anything.
It happened again the other day so i took one of the HDD's (its on a RAID 10) and gave it to our computer forensics guy and he made an image of the drive for me on another HDD (SATA).
I was wondering if anyone knows of a program where i can view the contents of the drive? Since this is esxi 5 I think its a GPT and not VMFS but im not sure. When i see the drive in disk manager it does mount 2 partitions. one says esxi and the other doesn't say anything but i do see its 4GB in size. My windows machine mounts it as drive O: but whenever i click it windows says it needs to be formatted.
I've tried diskinternals.com but it doesnt find anything. I've tried mounting it in ubuntu but ubuntu cant determine the FS either. Does anyone else have any suggestions?
