Hi Skylar,

I'm confused by your question.  You say you are doing migration from the
target to the source.  But that doesn't make sense.  In server-to-server
virtual volumes, data is sent from the source to the target.  Your
configuration shows that you have a storage pool called ONSITE-MALI on the
source that uses the server device class W_MALI.  Are you migrating data to
that storage pool from a disk storage pool?  If so, then when you do that,
you will see the archive filespace for the source server on the target
source get larger.  You can see the virtual volumes on the source server by
looking at your volume history file (q volhist).  When these volumes are
reclaimed or deleted, then the source sends a delete archive filespace
command to the target.
