When you say "physical device", do you mean real rotating media? Your V960 sprinkles data associated with a specific device address across all its arrays -- you don't allocate device addresses to specific drawers or RAID5 sets. So you are already getting some unit separation. As for simultaneous I/O to a logical device, I don't think your V960 supports PAV. Probably the closest you can come is to use LVM to stripe your logical volumes across multiple S390 device addresses. Check the archives for gobs of PAV and LVM discussion: http://www.mail-archive.com/linux-390%40vm.marist.edu/ And not that it applies to your case, but there is a document that discusses Linux, VM, LVM and PAV here: ftp://www6.software.ibm.com/software/developer/linux390/docu/lx24pav00.pdf -- David Andrews A.
