Hi Doug, Thanks for your response. A follow up question: I have a RAID controller and I create an LU on this controller. Can I use add-single-device to discover this LU (I know the host,channel,id,lun tuple)? I cannot do this with the ips driver, (I have to reboot) so I am trying to get a headstart before I start to debug further.
