[CentOS] mdadm syntax

I am trying to create an MD device. I am using the command:
/sbin/mdadm --create --a /dev/md12 --level=1 --run --raid-devices=2
to create the device, and to dynamically create the device file if needed.
What I want is the device file to be created as /dev/md12, but with the -a
flag it creates it as /dev/md<first unwsed minor number>.
I have tried various options to the -a or --auto, but cannot seem to find
the correct syntax. From the man page it says:
Instruct mdadm to create the device file if needed, and to
allocate an unused
minor number. "yes" or "md" causes a non-partitionable
array to be used.
"mdp", "part" or "p" causes a partitionable array (2.6 and
later) to be used.
The argumentment can also come immediately after "-a". e.g.
Am I doing something wrong, or is there no way to get mdadm to automatically
create a specific device file.
