I'll try it tomorrow. Even if it does work, though, the loss of manageability for LPAR mode probably would argue against doing it in production. > b) If I run Linux under VM, is it possible to boot a Linux guest > from a FC attached DASD (dedicated DASD?) ? Not with any of the current commercial distributions. There are experimental kernels -- so it is possible -- but not if you aren't prepared to do your own kernel support. > c) Where can I find info about FC-support on mainframes on the Web > (e.g. Redbook, IOCP-defs) ? The documentation that comes with the FCP microcode is pretty detailed. There was a presentation at the last SHARE on SCSI support and the details of how/if to do it. Neale's had it for a while -- maybe he can add some observations. -- db
