Snapmirror question

Hey,
 
we are using snapmirror since a few months now and its all working well. i recently forgot the steps that are needed to copy a new volume over to our other netapp.
 
site a volume32 should be snapmirrored to site b
 
created sitea_volume32 on siteb with the same size. restricted it over the webpage.
created a new snappmirror schedule where sitea_volume32 should be going to siteb_volume32. when i press initialize i get:

test5> snapmirror initialize -S test:lunvol32 test5:b_lunvol32
