Disk - LUN (Logical Unit Number).  In SCSI, each target can (in theory) 
have 7 LUN's (this may have changed, this is based on my old, cobwebby 
file drawer in my head). In fact, on the old SCSI<->MFM/RLL/ESDI 
adaptors (Adaptec ACB 4000/4070 and Emulex MD-21, to name a few), there 
were two LUNS available, making them lots of fun to play with.

Ya always fsck the raw device.  In the olden SunOS days (pre 5.0), it 
was /dev/sd0a and /dev/rsd0a...
