It should -- I don't have any to test it, but the Linux DASD drivers are pretty tolerant of odd sizes. They don't tolerate PAV (at least for booting) yet, though. > Also, the shark is being used to share dasd with open systems over > fiber.

You would need the FCP microcode for the FICON adapter (which effectively turns it into a FCP adapter and you lose the ability to access FICON-connected disks) and the FCP disk device driver for your Linux system. See your CE or IBM rep for the former, the developerworks WWW site for the latter. Note that when you convert the FICON adapter to FCP, you need to plug it into a FCP port on the ESS, not a FICON port. -- db
