I tried to not look directly into the port, but indirectly verify that 
there was no light.  My remaining eye seems to be ok. :)

Well, this was working fine for three years until 6:45 AM yesterday 
morning.  Nothing else happened on the server at that time.  It's a 
windows server, so probe-scsi-all doesn't get me anywhere, but i tried 
poking at it in a few directions with SANsurfer.  As far as it is 
concerned, the HBA is fine, but the loop is down.  That led me to 
believe that it might just be the GBIC, but i can't easily pull out the 
GBIC with  it mounted in the rack, so this will probably have to wait 
until the evening when i can pull out the HBA.
