Uninstall (deactivate) a Software RAID1

How do I uninstall/deactivate a Software RAID1 that was setup during the installation of Red Hat Enterprise Linux 5.1 on an IBM P5 Server?

mdadm --manage /dev/mdfoo --fail /dev/sdfoo
mdadm --manage /dev/mdfoo --remove /dev/sdfoo
mdadm --manage --stop /dev/mdfoo

mdadm --zero-superblock /dev/mdfoo
mdadm --manage --zero-superblock /dev/hdX
mdadm --manage --zero-superblock /dev/hdX

And finally, change partitions' IDs to something different from FD
(Linux RAID Autodetect). Just use fdisk, cfdisk, or whatever.
