Client has a DELL R710 with a the DELL custom ESXI 6.0 installed and about 4 VMs defined. It has been running fine for a couple of years, but just started behaving strangely. It seems like it is spontaneously rebooting, as I will remote in to find all the VMs off. I cannot access the iDRAC to check the the server status, and there is nothing specific to a reboot listed in the VMWare event tab. The main summary page does not show an "Uptime" status, so it is not clear how long the host has been running.
Looked the VMWare system logs, but cannot really decipher the contents well enough to make a determination.
In the Health section, all the sensors report green / normal.
Can anyone advise on how best to troubleshoot and diag?
