Server specs:
Latest BIOS on all 4 nodes
c6100 xs23-ty3
192GB ram
12 1TB drives
Y8Y69 mezzanine card in each node
pci-e dual gig nic in each expansion slot
dual 750W PS (green lights on both)
So nodes 1, 2 and 3 have ESX on them and are up and running wonderfully. Node 4 was left as spare and was to be outfit with drives on the fly in the data center but it was tested and booting / posting properly. Working with the local support in the data center we had them put three drives in node 4 and power it up. When they hit the power button for node 4 we noticed node 2 become unavailable in vSphere.
Connected to all 4 nodes through a remote KVM we noticed node 2 did in fact reboot. In summary, pressing the power button for node 4 is causing node 2 to reboot. This may be random and have not been able to confirm that only node 2 is subject to reboot...it could be any node.
***NODE 4 was booting and posting fine....obviously to a "NO OS" screen. We will probably migrate to another physical server and bring this one in for service but any comments are greatly appreciated.***
