I have just got a MDS 9124 swith to replace an old Capellix Gadzoox 3000 unit.
Basically, I have just removed the Gadzoox and added the Cisco switch in its place.
There are only 8 ports used. 3 x HBAs, 4 x Tape Drives and 1 x JBOD.
The problem that I have is that when everything is connected together through the switch nothing seems to talk to each other. I can FCPING each of the divices individually from the switch.
Now all the 8 ports are in VSAN 1 and I have set the default-zone to permit too but still no success.
Put the Gadzoox back in circuit, it all works but nothing with the Cisco.
Fibre channel is definitely a different beast to Ethernet!
