> > It took a lot of work, but I think your problems are dealt with. Success! It all works. The paths all failover when the fabric goes away, and all get added back when the fabric it re-appears. The only problem I had was that multipathd crashes on startup if it is compiled with -O2 on ia64. Compiling the deamon without optimisation solves the problem. I've not been able to test a controller failure; the HSVs I'm running against are in production for other systems. However, I should have access to a dedicated pair of HSV in a few weeks, so I'll be able to do the test I'll be able to test breaking the controller. Thanks for all the hard work!
