We have storage connected to switch 1, and hosts connected to switch 2.
Both Brocade 300.
Full Fabric license are in place (but not Trunking License)
Hosts connected to switch 2 does not see storage connected to switch 1. They do if we connect the storage directly to switch 2.
Obvously, we are configuring the Fabric and/or the link between the switches wrong.
We observe that 1 port is in downstream and 1 is in upstream on the link.
Any help is appreciated!

--->>> We observe that 1 port is in downstream and 1 is in upstream on the link.
such message is a sympthom Switch Domain ID is set wrong or with other word, both switch have same Domain ID.
if this is the cause, set the switch disable "switchdisable" -> execute the command "configure" and change the DID.

Zoning: Yes, and yes, the host on SW2 was zoned to the storage.
Unfortunately, we had to reverse the setup, so fabricshow and switchshow in question is not available.
Howvere this was how it was set up:
SW1: Domain ID 1
SW2: Domain ID2
(once the domain id was changed on one of the switches, the Fabric Tree showed the 2 switches)
After the 2-switch Fabric was established, we configured the zones like this:
Zone on SW1 and SW2 the same, with the following ports:
Port 1.0: Storage on SW1
Port 1.7: Link to SW2 (lw, 'Additional Port Info' showed upstream)
Port 2.1: Host on SW2
Port 2.7: Link to SW1 (lw, 'Additional Port Info' showed downstream)

Usually you don't add the ISL in a zone.
It was enough to create 1 zone in the fabric as such
--Port 1.0 #: Storage on SW1
--Port 2.1 #: Host on SW2
But zoning in this manner is a bit dated and tricky as the webgui anly show the local Port.
If must use D,P zoning ok otherwise try to switch to wwpn zoning

not really upstream downstream tells if you're getting closer (up) or further (down) from the principal switch.
added a picture for clearification
eitherway henning already posted the switches hae differnt DID's.

I did notice the difference and opted to comment that DID's where supplied to make it clear for whomever is reading the threads and jumps to the last post.
If you don't like it that I did so, please don't reponds to it.
It makes your message useless since its NOT contributing to a solution for henning.
When I'm wrong about the technical part of my post, than go right ahead to correct me.
As we are here to learn and benefit from each other's knowledge and experience.
My 2 cents and now back ontopic, so henning can go forward on this issue.

Just to make sure;
Do I have all the licenses neede in place?
The only applied license installed above the default is Full Fabric (in both)
I get confused when I read Brocade documenation, whether the Trunking License is neede or not.
