+
+## Utilisation
+
+### Lister les disques 
+
+Sur une machine avec un seul disque :
+
+~~~
+# smartctl --scan
+
+/dev/sda -d scsi # /dev/sda, SCSI device
+~~~
+
+Sur une machine avec du RAID hardware :
+
+~~~
+# smartctl --scan
+
+/dev/hdd -d ata # /dev/hdd, ATA device
+/dev/sda -d scsi # /dev/sda, SCSI device
+/dev/sdb -d scsi # /dev/sdb, SCSI device
+/dev/sdc -d scsi # /dev/sdc, SCSI device
+/dev/bus/0 -d megaraid,0 # /dev/bus/0 [megaraid_disk_00], SCSI device
+/dev/bus/0 -d megaraid,1 # /dev/bus/0 [megaraid_disk_01], SCSI device
+/dev/bus/0 -d megaraid,2 # /dev/bus/0 [megaraid_disk_02], SCSI device
+/dev/bus/0 -d megaraid,3 # /dev/bus/0 [megaraid_disk_03], SCSI device
+/dev/bus/0 -d megaraid,4 # /dev/bus/0 [megaraid_disk_04], SCSI device
+/dev/bus/0 -d megaraid,5 # /dev/bus/0 [megaraid_disk_05], SCSI device
+/dev/bus/0 -d megaraid,6 # /dev/bus/0 [megaraid_disk_06], SCSI device
