I'm getting used to the new concept of SGs, PGs, IGs and MVs on the VMAX 20k.  After creating the Masking View everything is automatically mapped and masked.  But what if I made a mistake and needed to back out.  For example say I entered a wrong HBA WWN into the IG or a wrong port into the PG  or a wrong volumes into the SG and then created the masking view.

Can I back this out simply by deleting the masking view?  Or will I have to do some other manual work to clean up mapping/masking entries?

I'll be presenting a bunch of storage to a lot of mission critical hosts and want to make sure I have a good backout plan in case I make a mistake.
