Zone out the portID for the second path on the servers in the HBA
configuration on each server (you'd probably zone out a different path on
each server depending on the switch they're in).  Everything can be done
this was in the operating system without needing interaction on the switch.

Hmm, losing the second path ... so if the switch where I'll get my
first path blows away I have no chance to get NB back running without
changing the switch ...

Maybe I'm too influenced designing clusters with storage arrays ...

Regards an thanks
