...tell it to validate the storage only between 2 Prod nodes, and also validate the storage for the 2x DR nodes only, if all 4 nodes are in the same cluster now?
That's what I am struggling with now in my virtual lab,
node1 > storage1
node2 > storage1
works like charm, then I've added
node3, node4, and I want to add storage only for node3 and node4, and there configure second WFC, and later run AO between them
my final idea is
node1,node2 : same dc1, part of 4node metro cluster, hosting SQL FCI "DC1SQL"
node3,node4 : same dc2, part of 4node metro cluster, hosting SQL FCI "DC2SQL"
AO from DC1SQL to DC2SQL
seems impossible...
