I'm assuming that the 3 drives are hdb, hdc, and hdd and each has a partition created.
Code:
Creating the array
mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/hdb1 /dev/hdc1 /dev/hdd1

Query the array
mdadm --query /dev/md0
if /dev/md0 doesn't exist, you'll have to create it. I think its mkdev /dev/md0
I hope I didn't have any typos

Two things I'm not sure of.

1. Why you would want to stripe a raid across 1 disk.
2. That it is even possible to do that

When I read your post, I just assumed you meant disks not partitions.
