With the default settings in my Supermicro motherboard CentOS calls my SATA drive /dev/hda. If in bios setup I change 'Native Mode Operation' from auto to 'Serial ATA' it boots up calling the drive /dev/sda. I keep thinking its likely better under /dev/sda not? Any problem switching it to that after install?
If you have setup lvm and use labels for mounting your filesystem, the change should be hassle free. Otherwise you have to check grub.conf for the root parameter and change blockdevices in /etc/fstab.
I don't use LVM yet, but I found that using hard-coded /dev/sda?? or /dev/hda?? in /etc/fstab is not recommended.
If LVM supports them, partition labels are the way to go.
A partition label is a filesystem property so you can give an LV's filesystem a label if you choose to, but this isn't necessary because LV names are persistent.
