MSA2324fc Changing default mapping to explicit mapping

Hi 

 

We have just one MSA2324FC hosting a number of VMs shared between two physical hosts

 

Originally each of the the physical hosts only had a single HBA each therefore single fibre path to the MSA - the mapppings to the volumes were set up as explicit - several months later an extra HBA was fitted to each of the hosts and the new mapping to the volumes setup - unfortunately the window to do this was literally 10 minutes - the option to configure explicit mappings didnt seem to be there - so the HBAs mappings are set to  default - hence question is it advisable or possible  to try to change these from default mappings to explicit to match the other HBAs and if so how can this be achieved - to do this -would it impact the live environment  -any help grate for

 

one other qustion can you back up the config on the controllers - if so how?
