We have inherited an IBM HS21 Blade Centre with a DS4000 SAN. I am trying to Map Hosts to Logical Drives to Create LUN's. Unfortunatly, I can only see the 4 Hosts (Blades) that came already discovered on the SAN. I can't get the SAN to discover any of the other Hosts. I click on 'Configure Host Access (automatic)' and it doesn't find anything. I try to click on the 'Configure Host Access (manually)' but it will not open. Can anyone tell me how I can make my Blades (hosts) auto-discoverable by the DS4000 SAN?
