I have a disk, 4GB, initialized under VxVM control.
I mirror the disk, using hardware, to a 8GM disk.
I offline the 4GB disk.
I bring the mirrored 8GB disk into VxVM.

As expected, VxVM views the 8GB disk as a 4GB disk.

Is there anyway to extend the disk, without losing data,
to the full 8GB size?
