to change the backend you can use this procedure: emc174327  as far as changing CIFS server subnet mask, that's easy. You would go under Network, select your interface, properties and then change the mask.
Hi, at a customer, i need to change the subnet of the celerra Public IP from 255.255.0.0 to 255.255.255.0. I think to change for first the celerra manager subnet, the spA subnet, the spB subnet and for last the CIFS subnet. There is a best practice? Any suggestion? Thanks in advance....  Sorry for my English
