removing the group lead from a 2 member group

Hello,

I have a group with an FS7600, a 4000, and a 6500. I have removed all my shares and deleted all the volumes presented to vmware. Only my new SC array shows in vmware. I have 4 volumes left that are in the default pool. I want to remove the 6500 but keep the group intact with the 7600 and the 4000 (going to add a 6100 later and use it at a different location) the end goal for the 6500 is for it to be a replication partner with the SC. I can't delete the member, not enough space for the volumes on the 4000. I can't delete the volumes, they show an ISCS connection to the 6500. 24 of them in fact. how do I either A remove the volumes, or B change GL so I can remove the 6500 (i think thats the issue, its GL). I have all my data moved.
