Can not terminate / remove SYMCLONE BCV on VMAX2- 10K ?

I have "inherited" a config where i need to clean up as we get rid of the VMAX2-10K Arrays. What i am trying to do is clear the External Disk Pool (FTS) by rebinding and migrating to the Internal Disk pools - so we can then sort / delete or migrate data...onto new arrays BUT - i have come across a device i can not move due to a BCV connection :- This looks like an old Symclone command as it shows under "symclone -sid xxxx list" but is a mess and i can not get rid of it ... I have tried a TERMINATE with a file / DG but get the error "A configuration mismatch was detected among members of your META device(s)" Some device details:- symclone -sid xxxx list Symmetrix ID: 00029870xxxx Source Device Target Device Status ------------------------- ---------------------- ------------- Sym Protected Dev Tracks Sym CGDP SRC <=> TGT ------------------------- ---------------------- ------------- 1246 0 0662 X...
