A tale of two switches
Hello,
At our DR site we have not purchased a Director Class switch for our environment. Instead, we have purchased two pairs(4) of MDS 9148s for our arrays, servers, data domain, etc.
The configuration would be two fabrics, 1 pair for VSAN 100 fabric A, the other pair for VSAN 200 fabric B.
I have DCNM installed and I can see the see pair, 1a, 1b as the fabric(s) defined.
1a, 1b have redundant paths for the VNX, Recover Point and Data domain ports. I would like the 2a/2b side to host the servers that I can zone to the storage array.
My question is can I make the first switch 1a, the principal, and the 2nd (2a) edge the subordinate by creating an ISL link between the two. I would like both switches in the same vsan(1a, 2a, vsan100), 1b,2b(vsan 200).
I have only done this using the core-edge topology so I wasn't sure if I an do this with edge-edge.
Thank you in advance

copy and paste from the Cisco forum ..or did you post here first ?
Benita,
why do you care about principal role, if one of the switches fails, that role will be assumed by the other switch in the fabric.

So a couple of strange things happened. I created the ISL between the two switches. It came up, however, the new switch thinks it the principal. This looks odd in fabric manager since I downloaded dcnm and made the seed switch the first of each pair since those were the original switches with the zoneset(1a, 1b). Even though I said to enable the full zoneset, and it sees it in the running config when I do a show zoneset, nothing shows up. I see a clear zoneset issued with the running config which is odd. This is also how it looks in DCNM.
zoneset distribute full vsan 2

Reset the priority so now the right switch is the principal, however, I am still seeing that error in DCNM and the zoneset did not distribute.

I think I know the issue, the passwords/id is not the same for the two pairs of switches.
Will change it.
