Can someone confirm my understanding of this feature is correct:

I/O Shipping does not help in server or storage failures - it help in disk path failures like HBA card or FC switch failure, but this is what DMP provides, so the use cases of I/O shipping are:

You only have 1 path to the storage
You have multiple paths, but they all fail.

As both of these are not that common, I am wondering if I am misunderstanding what I/O Shipping provides.
