installed rhel wrong, boots to red screen instead of cli
 

I just installed rhel for the first time, I thought I unchecked all the gui's when I used the graphical installer, but when it boots, it boots to a red login screen. I wanted it to be gui free, cli only. What did I do wrong? How can I fix it?

Its also says memory for crash kernal 0x0 and 0x0 notwithin permissible range and sda asking for cache data failed AND sda assuming drive cache write through, right before it gets to the red login screen. boy i really didn't do this right :'(

It's booting to runlevel 5. To change it to runlevel 3 (multiuser cli), edit /etc/inittab. Look for this: id:5:initdefault:
Change it to id:3:initdefault:

Cool, so maybe I didn't mess it up that bad after all?

Any idea on those couple messages I see on the black screen before it starts to go red?

I see the Crash Kernel one alot on CentOS too when it has GUI, I believe it's to do with memory dumping. Basically you haven't assigned an area for it to dump memory to, it's an informatative message only and isn't anything to really worry about.

Not certain about the cache test failure, however it's assume responsibility for the write caching itself to compensate for it... Is this a phsyical or virtual server?

its a physical server. I have 2 drives RAID1 with a hot spare. i'm so confused.

So should I have enabled kdump when I installed the server? thanks for that link.

That did fix it, thanks.
