A change of scene. Hou about a linux question?

[Rick Bowers]

I run my mail server on an e-smith (Mitel networks) server.  It's based 
on RedHat linux.

I've re-installed the software recently  because the upgrade wouldn't 
work.  I installed to a new disk, and have the old disk in the server, 
also.  To get my files from the old disk, I

mount /dev/hdc1 /mnt/hdc1
mount /dev/hdc6  /mnt/hdc6

Here is the problem.  During the boot process, the system is, for some 
reason, mounting /dev/hdc6 on /
I've looked around and don't see any reason this is happening.   There 
is nothing in /etc/fstab.  /etc/grub.conf shows root=/dev/hda3

I don't  know how to run grub, so maybe the issue is there. 

Any thoughts?  What other information would be useful to help debug this?
