One of these rules is that - of the two paths to a single disk storage stack from a single node, one should connect to the top and one to the bottom of the storage stack. If you are informed either by MyAutoSupport or another source that this particular rule is being violated, this article shows how to diagnose and possibly remediate the issue with no downtime.
