So, can we safely say that by failing to follow the rules, one can break any implementation of a technology that involves two or more components? Whether it is drives on a PC or code on Mac or even, as hard as I find this to believe, the 3K? I have seen a third party use other name brand third party software in ways the 'crashed' our 3Ks. Before that, I only saw one crash when it lost LDEV 1. Since then, I have read and heard amazing things that could crash the 3K. As to following the rules, one can say much about the reasonableness and accessibility of those rules. On a better day, I could say something witty about aberrant behavior on the part of one's spouse when unreasonable and unknowable rules were violated...
