Is IVR possible using a "router on a stick" ?
Hello people,
I'm facing an inherited SAN design where IVR is done by a 9222i which isn't in the "line of sight"... if traffic flows over the shortest path (FSPF ?), the 9222i isn't on the route.
I'm now facing problems with the routing of traffic between 2 VSANs.
In Fabric A it works fine, but in fabric B it doesn't.
EMC says in the SR I've opened that the 9124 on the right should be IVR capable, but I doubt that very much.
A colleague of mine says it should be done like this:
What do you think ? All help is appreciated !

this is from "Inter-VSAN Routing Configuration Guide"

i would think that the first picture would work as well, what is your ivr topology ?
sh ivr vsan-topology
so what happens when you try create an IVR zone, you don't see Clariion2 WWN that are logged in to 9124 on the right side ?

On one fabric mirrorview works fine, but on the other fabric I can't see logins anymore at all. Deleting the IVR zone and recreating it doesn't help.
The fabric in which we have problems the VSAN number is 1108 by the way.
AFID SWITCH WWN Active Cfg. VSANS
-----------------------------------------------------------
1 20:00:00:05:73:d5:b8:80 yes yes 1126,2250
1 20:00:00:0d:ec:82:61:c0 * yes yes 1101,1121,1125,1500,2250
I'm now working to get a change approved to move the portchannel from the 9134 to the 9222i. This way the IVR switch isn't a "router on a stick" anymore.

hmmm, on the other 9222 the topology is:
AFID SWITCH WWN Active Cfg. VSANS
-----------------------------------------------------------
1 20:00:00:05:73:d3:78:40 yes yes 126,250
1 20:00:00:0d:ec:82:62:c0 * yes yes 101,108,113,121,125,150,250
The VSAN we're using there is the 108.

Clariion 2 logs in just fine on the 9124 on the right. It's on Clariion 1 where I don't see Clariion 2 loging in. At least SPA1 isn't logging in, SPB1 works just fine over the other fabric.

so why am i not seeing VSAN 1108 as part of your IVR topology ?

I don't know. I didn't even know this command until you asked me to run it. I've searched where I could "insert" the missing VSAN, but I can't find it.

you already have ivr enabled so you just need to go into vsan topology database and add that VSAN.

Thanks, that worked. But I'm still puzzled why it used to work and suddenly it wasn't working anymore. I must admit that I didn't even know about this. I'm managing inherited VSANs and never had to add new ones yet.
Thanks.
