I love these blog posts by the Ask The Core team and i think everyone should subscribe to their blog, they do not post often but when they do its worth while….

 

this post represents a problem for which i have seen many a time what it comes to clustering with hyper-v and let me assure you to date its never been a windows / hyper-v issue, it has always been network related / fibre channel related.

In my experience it is almost always down to a dodgy cable but in the case your problem is not the same this guide will help you on your way to discovering the exact issues.

 

Enjoy and thanks to the Ask the Core Team Again!
