Re: Reboot after kernel grub update fails

I then was able to escalate privilege to root and remove the last kernel package installed which removed all of its associated (child) d...

Re: Reboot after kernel grub update fails

Reboot after kernel grub update fails
We, a coworker, just upgraded our system which included a new kernel, 3.10.0-1160.13.1. Then we rebooted the machine and after selecting any entry from the grub menu, the server simply hangs. The rescue menu item also does not work. This is on a Red Hat, not CentOS, server. Any ideas what could have...

[RESOLVED] - How to confirm power chords and power supplies are plugged in
I have a few servers that are running with two power supplies, and one power chord/power supply; basically two power supplies total and two power chords total. Should I not be able to use dmidecode --type 39 to determine if a power chord is unplugged, or similarly, if a power supply has been partial...
