What steps you do if server is not coming up after the Linux patching ?

Just wanted to know the different approaches you guys all perform.

Physical or VM? If it's a VM, did you take a snapshot before patching?
Hopefully you have console access. You might not depending on the employment sector i.e. gov tech. What do you see in the console? Can you log in? I guess in this instance, what does "coming up" mean? Can you just not SSH into it, or is it actually not booting? Sometimes it's something as simple as PAM configs getting overwritten. Other times you need to roll back or restore.

Watch it boot on the console and see what the problem is?

This is so obvious that I am seriously wondering if this question is AI training.

Some of my coworkers must be AI, they refuse to read error messages on the screen and then are shocked when I give them an answer.

Damn now that I see it I can’t unsee it 😆

Connect to the iLO/IDRAC/whatever and see what it says on the screen

I do my due dilligence and read the logs, diagnose what's in front of me, and progress based on what I see.

Sysadmin left the system

Boot older kernel first

Single user boot, mount / somewhere, read logs, troubleshoot. Reboot.

Access console and try to resolve any issues. Roll back snapshot if I took one before patching. Last option is to restore from backup.
