Moving Disk Transparently From Host Point of View

I am Mainframe System programmer and new to EMC storage. I have a question: "sometimes there would be some problems on storage and there is a need to move data from one particular physical disk to another physical disk(full copy) or even rarely, release whole storage box for some hardware maintenance. Does VMAX 20K/40k have any functions to move whole disk transparently from host view? for example can we move SYSRES(live operating system) from one symm device to another symm device in a live system without any disruption?"
