Is it recommended to assign a LUN to multiple storage groups? - If you are working with clustered hosts, yes (ESX, MSCS, etc.). Non-clustered hosts, no  What will happen? - You can possibly corrupt data  In case of boot LUN? - Each server should get its own storage group. Boot LUNs should be unique for ecah storage group and the data LUNs will be presented to each server's storage group. Just make sure you match the HLU's when adding the data LUN to two or more storage groups.  Can you add a LUN as read only? - Yes, if you are running Flare R31.5.5xx or greater. It can only be done from the cli and the command is: naviseccli -h ip storagegroup -addhlu -readonly
Hi,  I would like to know is it recommended to assign one LUN to multiple storage groups? What will happen in this situation? Can we make the LUN read only? If both the server writes to the LUN, will it get corrupted?  Incase of a Boot LUN, do we allocate one LUN to multiple hosts?  Please help.
