Ok, I am sorry, if I have annoyed someone with my reply..
I didn't mean it.. It's just the problem was very crucial to solve as soon as possible, and nobody was answering..
By the way, FYI, I have found the solution and it is - "cu"..
I knew that AIX has a huge amount of utils, but couldn't recall this one.. You can find out everything by : man cu
About the documentation on ILS, I have the documentation from IBM, but it is not very detailed, you know.. So I was having problems with setting up a link between two Fabric switches..
But as I have found out, the problems was in wrong zoning and that the domain ids of each switch was same...
