Disable prompting for passphrase at boot (encrypted disk)

I have an encrypted disk, using LUKS / dm-crypt, on Fedora 14.

Every time I boot, I am immediately prompted for the passphrase. This happens VERY early in the boot process, and is a graphical screen (ie not console text). If I hit escape, I am prompted in a text-mode for the same passphrase. If I hit escape or return a few times, boot continues normally.

I only mount the disk occasionally, and don't want to be prompted at boot for the passphrase to luksOpen the disk at boot. I manually cryptsetup luksOpen and then mount it when I want access. I just don't want to be asked at boot, and don't want to unlock it until I do so manually.

Does anyone how how I can tell Fedora to not attempt to decrypt / mount this filesystem at boot?

It's not in /etc/fstab.

I should mention, no LVM, just mdadm raid5 on the partition + luks /dm-crypt.

Any help or tips would be appreciated.
