Excluding unwanted dependencies from yum update

If you like to use YUM (Yellow Dog Updater Modified) you may know unwanted bit dependencies always comes with updates and messes up things. To prevent unwanted i386, i586, i686 dependencies you just have to add
exclude=*.i386 *.i586 *.i686
this line to
/etc/yum.conf
so it will never install or update this dependencies. As this configuration above it will only install and update 64 bit dependencies.

Set up RAID on Dell Poweredge 2850

Today I had a hard day. Our server HDD crashed (I think it had a bad sector or something? Friend of mine checked our server and said it's hard disk broken) and we had to change HDD. We got 4 SCSI HDD (72gb) for a cheap price. And decided to make a RAID. But it is way harder than regular PC RAID. I've followed THIS tutorial and settled up very good raid configuration. But real problem was just started. After setting up raid and installing nice clean centos 5.5 I decided to put a old HDD into server and copy files from there to new HDD. But server won't recognize my old HDD cause of RAID configuration. So I had to add old HDD as a RAID. And BOOM all Data is gone. It was very stupid step :( . I didn't find a way to add (mount or something) a HDD to RAID configured server. If you have solution for this pls share with me. Also I wanna restore my old HDD data. Is there a way? And again never ever try to add HDD to a RAID as a RAID
