So your VNX has two SP’s and you have two fabric switches. You already know you have to connect each SP to each fabric for resilience, but you’re still a bit confused. Fear not. Use this as a guide. It can be used no matter how many front-end port modules and SFP’s you have so that you get it right first time for all your designated Storage Ports, Mirrorview Ports, Sancopy Ports required for your project. The FC Switch Ports you choose are not set in stone, but keep it the same on each side at least.
What’s important is that the correct SP port, goes to the correct switch.
When you know you’ve got it right, you can get verify the WWN in Unisphere corresponds with the WWN logged in on the FLOGI database on the switch to check before you create the requisite fcaliases etc.
It’s much easier to build it right first time than sort it out afterwards.
