Building on my previous question about RHEL, how do you add get the guest OS to recognize that you've added new drives to it without a reboot?

I have Windows 2003, XP, and 2008 guests running on ESX 4. I've added new virtual disks to the VM, but have not figured-out how to get the guest to recognize them without a reboot.

Is this possible? If so, how?

You should be able to go to the disk management snap-in (diskmgmt.msc) and go to Action -> Rescan Disks.

That will detect any new disks and pop up the windows wizard to initialize them.
