(ie could we write a method that would do that?) My current situation is that I have a couple of IBM ESS F20 Sharks each with 3 fibre channel cards hooked to 3 brocade switches. When I allocate a LUN out of either shark it appears as 3 separate devices. IBM ship software called "SDD" that provides a single virtual device "VPATH" on NT, Solaris and AIX and load balances. At the moment when I hook up a FreeBSD box I just select one of the devices and ignore the others. Mildly annoying and I have to bring down the FreeBSD boxes when we upgrade the microcode on the shark. Carl.
