Re: Configure multiple initiator zoning to single initiator zoning
If you are not changing anything on the array and are not doing anything with VMFS partitions on LUNs you should be on safe side.Even if host detects a permanent device loss and then at some point...

It depends...Theoretically the risk of having multi initiator zone related fabric problems in 3 host / 1 array environment is fairly small, so you might go with a concept of "dont fix it if it ain't...

your current config is ok, no need to worry too much, for each subnet just use one pNIC, that is what the DELL paper says, and that is what i also mentioned in my first post, an one to one mapping is...
