Look in /var/log/dmesg to see what the kernel called it when it 
found it (if it did, it may not have) during the initial scan.

You may have run into a RedHat gotcha if you are using the stock 
kernel.  The stock kernel does NOT "scan all luns", thereby missing 
a robot device thats on the same bus address, but at lun=1 (or 
higher) as opposed to the tape drive itself which normally defaults 
to lun=0.

LUN is Logical Unit Number.

If thats the case, you'll have to build a kernel that does this.  
Its a ready to check option under the scsi menu in a "make 
xconfig".  You shouldn't have to do anything else, although I 
brought my scsi card driver into the kernel instead of as a module.

If the robot is found, you should see something like this in your 
dmesg file:
