Just by way of further clarification of my Mark's accurate comment: 1. VDISK is in one of theses states: in core memory, paged out, or never referenced, i.e. it's treated as memory albeit looking like FBA. No actual FBA I/O occurs. 2. EDEV "exists" at least in the hardware. Feels like FBA to the virtual machine. Actual I/O occurs as needed. The real I/O's are not FBA CCWs rather are SCSI driven through QDIO. No actual FBA I/O occurs. David Kreuter
>Yes, you would. That's the whole idea of EDEVs. You let z/VM manage the SCSI >part, and Linux treats it just like >VDISK, for example. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
