CentOS - Nov 2005 - centos4.2:raid1:grub

Hi!
Whew, I have googled around a lot w/this but can't quite seem to come up
w/the right answer.

This system works beautifully w/nothing wrong w/it. But my goal is to be
able to test the raid system by just unplugging hda to mimic a faulty
drive and have it just carry on and boot from hdc.

md0 = hda1/hdc1  /boot (primary boot partitions on both drives)
md1 = hda2/hdc2  /

is it possible to just edit /boot/grub.conf???  I am really not sure of
this 

Thx in advance.

Can't you just do a software test:

raidsetfaulty /dev/md1 /dev/hdc2 (for example)

Check out the LDP 
http://www.tldp.org/HOWTO/Software-RAID-HOWTO-6.html#ss6.3 for details 
including how to add the disk back to the array.
