Hello,
We've had some strange experiences with our Dell Servers.
2 weeks ago, our main Hypervisor (Dell EMC PowerEdge R640) unexpectedly shutdown during the middle of the day. There was nothing useful in the event log, and the server booted back up fine when turned back on manually after removing the power cables and plugging them back in.
A few days later, the same thing happened again - however this time the server would not boot at all. PSU lights were on but nothing else. This ended up being a call to Dell and they came out under warranty as they said their was a problem with the motherboard.
Today - one of our older servers had the same thing happen. This machine is a Dell PowerEdge R710 (2010). Obviously this machine is out of any warranty.
Each server has 2 PSU's, One going to the main power supply, and one into the UPS.
Has anyone got any ideas as to 1, how we can get the R710 back online and 2, what on earth the root cause of this could be?
I just can't believe that it is a coincidence!?
