I am working on a project where we are implementing VMWare on CISCO UCS blades that are connected to a Clariion SAN. To take advantage of the UCS technology we want to boot our ESXi servers from SAN. Therefore I have created a Storage Group for each server which contains their boot LUN. I have read that a host can only be a member of one Storage Group so does this mean that I need to add the "shared LUNs" to each of the ESXi Storage Groups? Someone told me to just create another Storage Group and add all the ESXi hosts and "shared LUNS" but I do not think you can do this. Any advice would be appreciated. Thanks.
