After the upgrade the server rebooted and now it shows two options in the OS selection menu. Red Hat Enterprise and the ADE OS. I've tried booting into them both but get the same result, a dead prompt that won't accept any input and I'm unable to ping the IP I previously used for CPI. I can log into and manage the server with CIMC without an issue.
Also, is there a way to install the ISO from a USB drive? I tried to use the same method to make a USB bootable ISO from the ISE guide but it doesn't seem to work.
