For SVC, the SCSI ID goes in the first four hex digits and you append 12 trailing zeroes. I did a presentation "From zero hardware to Oracle RAC" at the z tech conference in Berlin a few weeks ago and that includes more detail on SVC configuration (XIV backend) of hardware, z/VM and Linux. I'll make it available somewhere tomorrow. --Malcolm -- Malcolm Beattie Mainframe Systems and Software Business, Europe IBM UK
