our client asks what is the Hitachi best practice regarding host groups and zoning. At the moment they have all host groups made available to all array ports (0A,0B,0C,0D,1A,1B,1C,1D) and then the zoning is done in the SAN switch.
Is this a good practice? Or should the host groups have only needed array port-s in them.
What is the best practice?
