"When equivalent hardware function is available, Guest IPL from Small Computer System Interface (SCSI) Disks - initial program loading (IPLing) from FCP-attached SCSI disks for Linux and other guest operating systems that contain support for IPLing from FCP-attached SCSI disks, when z/VM is running on a z990, z900, z800, or equivalent server equipped with the IPL-from-FCP-attached-disk function. IBM plans to make this hardware function available in the future." -----Original Message----- Mark, I think that z/VM 4.4 is now GA. If so, it allows IPLing from FC SCSI, from what I've read.
