A: LUNs can belong to storage group and be expanded B: LUNs don't have to be in a storage group to be expanded C: Layered application has to be stopped, LUN expanded, layered application re-created D: True.
HI All,   I am new to VNX, and I am preparing for my exam. Please correct me if I am wrong.  My understanding is, in order to present a LUN a host, it need to be in a storage group (or better in the SG for easy management) if you remove the LUN in the storage group, the host can't see the LUN  if this statement  "LUNS cannot belong to storage group when expanding" is true, So does it means that it can't expand on the fly?  As we know, VNX is definitely can expand the LUN on the fly, so is the statement is wrong? 
LUNS cannot belong to storage group when expanding?
