Or use lsscsi like this and look for lines with 'enclosu' in
its output:
   # lsscsi -gs
[3:0:0:0]  disk    ATA     ST3160812AS      D     /dev/sda  /dev/sg0  160GB
[6:0:0:0]  disk    SEAGATE ST200FM0073      0007  /dev/sdb  /dev/sg1  200GB
[6:0:1:0]  enclosu Areca   ARC-802801.13.1D 0113  -         /dev/sg2      -

Then:
   # sg_ses /dev/sg2
   Areca     ARC-802801.13.1D  0113
