I don't know... No, I looked at this also. All machines had access. What I did notice was that the switch was in a state with flashing ports so I restarted it and all seemed to go fine after that. > I can't imagine your storage being trashed by the FC network.

That's the other funky thing that happened and is why I posted asking if what I see from webmin is the same as what I see from the command line. I asked that because I was sometimes able to see volumes from one or the other. Either way though, I was not able to do anything with the volume I would see because I would get seg faults. The seg faults ended once I reformatted one of the devices, which is one of the one's back on line now.
