I have an ESXi 5.0 production environment using HP Lefthand storage and the default fixed PSP. I also have a dev 5.5 environment using round robin PSP on the same LUNs\storage as the production environment. Is this ok to do or will it cause problems on the storage? Eventually everything will be round robin but I don't want to mess with production and change it until I'm sure everything is working on 5.5 which will be the future production environment.
