[CentOS] Adding new Hard disk to server with RAID-5

Hi all,

I have Dell 2950 III with RAID-5 installed and managed by hardware Raid controller, I also use LVM when install CentOS. Now I get more 03 Hard disk and I would like to add it in to the running system. My question is:

1) if new hard disks add in to the machine, I have to rebuild the RAID volume with RAID management (raid controller) and the volume will be expanded, but is that make any problem to LVM at OS level ?

2) if (1's) answer is YES, what I need to do to prevent trouble occur ?

If any one exprience or know the place can help me start pls share. Sorry for the dumb question but I never did this before as a newbie Linux admin - I am 'handmade' former....Windows admin

Thanks for your help. regards.
