New virtual Disk Geometry does not match old geometry

Disk geometry problem
Currently we have storage directly provided to our machine from an EMC array
We are currently migrating to storage provided via a VPLEX device (same EMC array backend)
New LUNS have been provided (same number of blocks) but Solaris is identifying the storage with different geometry.
Consequently there is not the same number of blocks available.
Consequently we are unable to mirror our zpools.
Old storage vtoc
This problem is caused by the different geometry causing the 2 spare cylinders to use more blocks in the new storage (more blocks per cylinder)
