I'm not sure what 1:0:0:0 and 2:0:0:0 are or where they came from. They 
show up in lsscsi but there is no sd device assigned to them, obviously.

These LUNs do not exist in the array configuration. I only see LUNs 1, 
2, and 31.

The profile saved from my array is here:  http://tinypaste.com/73823

I added to /etc/sysctl.conf "dev.scsi.logging_level = 4096" and 
rebooted. The new syslog since the boot is here: http://tinypaste.com/5b72b
