Most server class boxes need to be booted into a disk utility application to modify storage.
HP servers come with a CD to boot with that will take you to a menu that permits you to add the new disk to the disk array.
The IBM euivalent is built into the ROM-Bios.
After configuring the disk, it will be available.
