How disassociate a lun from a deleted asset.,,

Hi,

I had a zone associated with a lun that was presented via the underlying vds service from a static block library. I deleted the zone from via the administration interface, however, the lun is still shown as being associated with the zpool identifier assign to the zone.

Relabeling the disk, removing and re-adding to the library still retains the association. I even used it to host a new ldom, but on deleting this, the association still remains. Obviously, there is a remaining association between the disk guid and the zone it was previously configured to use. How can I expunge this association from OPS Center?
