First comment is that Mother's Rule #1 (mix not data and system code lest peril ensue) applies here. It is a much better idea IMHO to have separate LVM spaces for data and system code. > I am > having a hard time finding information on mixing disk architecture in > an LVM.

VM emulates 9336 FBA devices on pure SCSI setups if you use emulation at all. FCP SCSI LUNs do not necessarily have emulation enabled -- you can choose to not use mainframe device emulation entirely if you have FCP storage, but you cannot manage that space with DIRMAINT or similar tools. > Is anyone out there doing this? It's probably wiser not to mix emulated FBA and true FCP SCSI partitions in the same LVM. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
