Xserve 4gb fiber not showing link, but Xraid says ok

I have an intel 2x2 dual core (10.5.8) with the 4gb fiber channel card. Both fibre channels run to upper and lower controllers on an older Xraid. Software is up to date and all has been running fine for 2 years.

One morning, the one raid array (1-7 is a level 5, and 8-14 are a level5), one of them was offline. There was no server restart, servers are on ups, no other history in logs except the time it suddenly went offline (from services shutting down).

Xraid admin says all is good on the Xraid, all lights green, all drives good.
Only ONE of the two arrays is not functioning (ie mounting). As from the Xraid standpoint it works fine. I've switched cables on the xserve fiber card and can get the opposite array to mount no problem.

What's puzzling is this:
Xserve fiber channel card lights on back show both green.
Xraid shows links established.
System prefs show Port 0 as no link. (which is of course why it won't mount or be seen by the system).

Is this a card failure?
Will be first I've ever had of this, but anything is possible.
Why would the Xraid think there is a link and why is the light indicating there is a link?

Before I go drastically fiddling with it, anyone else had this problem?

(I'll attach the profiler info)
