So I have several 6.0 esxi hosts doing boot from san via iSCSI. I pop in the ISO and go though the upgrade wizard. The boot disk is found and esxi is detected, there is only 1 boot disk. The upgrade finishes and the server reboots with 6.7, no problem. But if I restart the host again, it some how boots back up to version 6.0.
I've never seen this before and I have no idea whats going on.
