Each host needs access to each controller.
(Which looks like your drawing (I think))
example:
Host 1 port A-> NetApp-01 port e0c
Host 1 port B -> NetApp-02 port e0c
Host 2 port A -> NetApp-01 port e0d
Host 2 port B -> NetApp-02 port e0d
For Aggrs / vole / LUNs in this config... I’m going to assume you have 24 drives in there, you’d want to creat 2 aggrs, one on each controller. From there, the basic way is just do a volume / lun off each aggr and map to the hosts. Install VSC too, It’ll making mapping datastores easy.
and always test failover on each controller before it goes production.
