I got an email from smartd yesterday with the following error:

I understand this means the drive is probably going to fail. This
device is /dev/sda and is part of /dev/mapper/VolGroup00-LogVol00
Is it possible to replace the single failing drive and if so, what would
be the steps so that data isn't lost.

/dev/sda, is that your boot device? that will greatly complicate
things... and, your swap is probably not under LVM, /boot certainly
isn't so there's moer on that drive than just part of VolGroup00
I think I'd opt for plan B... install an identical new drive on another
SCSI unit, boot a standalone live CD, and DD image the whole raw
physical drive /dev/sda, then swap this new drive to SCSI unit 0 and
remove the failed one.
I discovered recently that getting exactly the same size (I am using
ATA) can be difficult, and two drives "the same size" can differ by a
few sectors.
I'm sure bigger is okay, smaller is not (but you might be able to fiddle
with /boot and/or dispense with the swap partition. I prefer swap files
anyway))
