Hi

Sending IP traffic over your SAN will at least make your SAN switches 
confused, as I believe that they do not talk IP, only SCSI commands.

I have installed two Emulex LP8000 adapters in an IBM P-Series 640. You 
cannot use the IBM drivers for the Emulex card, as there are no drivers 
for the LP8000, only for LP7000 and LP9000. Bull has drivers, but they 
won't work with IBM AIX, as Bull is at level 4.3.3.1 and I think IBM is 
still at 4.3.3.09.

When installed, the default value was FC Networking. When starting up the 
machine, we didn't get a link on the LP8000. However, after we had changed 
the setting to use FC-SCSI, the adapter worked correctly. Our problem was 
that the LP8000 couldn't talk to an 3584, as the tape driver talks FCP 
native, and the LP8000 talks SCSI down to the HBA. When we tried to 
install the IBM driver instead, the adapter driver couldn't load. After 
talking to both Emulex and IBM, we found out that IBM has changed the 
memory addresses for the adapter, and therefore, the IBM driver will not 
work with a native LP8000 adapter and vice versa.

Hope you get IP traffice to work through your SAN switches.

Best Regards
