Some advanced functions of the EMC CLARiiON are not supported by the SAN Volume Controller.
Advanced copy functions for EMC CLARiiON, for example, SnapView, MirrorView and SANcopy, are not supported for disks that are managed by the SAN Volume Controller because the copy function does not extend to the SAN Volume Controller cache.
MetaLUN allows a logical unit (LU) to be expanded using LUs in other RAID groups. The SAN Volume Controller only supports MetaLUN for the migration of image mode virtual disks.
