I'm adding a second 8 bay drive cage and an 12G SAS expander to a DL380 GEN9 server with a P440ar controller. My question is can I keep my existing RAID configuration or will I have to rebuild it after I install the second drive cage. The RAID configuration should be stored on the drives but I'm not sure the contoller will pick up the config after the SAS expander is installed
cheers
