Some things that you may have already checked:

1 do the switches have different domain IDs?
2 do the zonesets have the same name?
3 if there are zones with the same name on each switch, do they contain 
the same members?

I've not used Brocade switches, but all the other fiber channel stuff 
I've used has required those three things to be true before the fabrics 
can be merged; if the fabric merge fails, the ISL is taken down and the 
SAN is segmented.  I'd expect Brocade to at least require 1 and 3 to be 

You may also want to check that both switches agree about how the ISL 
should work - usually there's the vendor specific way and the 'open 
standards' way.
