Cannot mirror rootdg

OS - Solaris10 

Veritas SF - 6.0

I cannot remirror my rootdg after disassociating the plexes when applying the latest OS patch bundle to the server.  I was able to run vxdisk and vxdg and get the disk added to the dg but when I tried to mirror using vxdiskadm it fails with the following.

VxVM vxmirror INFO V-5-2-22   Mirror volume rootvol ...
  VxVM  ERROR V-5-2-673 Mirroring of disk rootdisk failed.
  Error:
