Thanks for all the replies.
The bit about combining zpools came from this command on the southbrain
tutorial;
zpool create mail \
mirror c6t600D0230006C1C4C0C50BE5BC9D49100d0
c6t600D0230006B66680C50AB7821F0E900d0 \
mirror c6t600D0230006B66680C50AB0187D75000d0

I admit I was getting confused between zpools and vdevs, thinking in the above
command that each mirror was a zpool and not a vdev.
Just so i'm correct, a normal command would like like
zpool create mypool raidz disk1 disk2 disk3 disk4 disk5
which would result in a zpool called my pool, which is made up of a 5 disk
raidz vdev? This means that zpools don't actually 'contain' physical devices,
which is what I originally thought.
You are correct that the above will have a single vdev of 5 disks.
Here's a shorthand note:
A zpool is made of 1 or more vdevs.
Each vdev can be a raidz, mirror, or single device (either a file or
disk). So, you *can* have a zpool which has solely physical drives:
e.g.
zpool create tank disk1 disk2 disk3
will create a pool with 3 disks, with data being striped across the
devices as desired.
