The question is whether the kernel will notice the new drive when you

with the setup detected at boot time but that doesn't sound very
healthy. Can you hotswap a new SATA drive that wasn't present at
boot time and have the kernel notice the new drive device and its
partitions.
Thinking more about this ...
I most likely wouldn't have a drive "ready" as all our servers don't
have the same configuration.
If the partitions are recognized, mdadm will be able to
add them.
Could I create partitions on a new drive (fdisk) and then do either a
mount or remount? And then start rebuilding the RAID?
Yes, but there is still the issue of whether the drive will be
recognized at all when hotplugged. Once the drive is assigned a device
name by the kernel you will be able to fdisk it. You don't need to
mount it because the md device will be mounted, not the disk partitions.
