* Per capire che dispositivo è, elencare i dischi
ls -l /sys/block/sd*

lrwxrwxrwx 1 root root 0 Dec 22 13:04 /sys/block/sda -> ../devices/pci0000:00/0000:00:1f.2/host2/target2:0:0/2:0:0:0/block/sda
lrwxrwxrwx 1 root root 0 Dec 22 13:04 /sys/block/sdb -> ../devices/pci0000:00/0000:00:1f.2/host3/target3:0:0/3:0:0:0/block/sdb

* In base al link, il numero di ataX è quello di target

* Usare questo semplice script:

<pre>
#!/bin/bash
# on Ubuntu get ata ID for block devices sd*
ls -l /sys/block/sd* \
| sed -e 's^.*-> \.\.^/sys^' \
-e 's^/host^ ^' \
-e 's^/target.*/^ ^' \
| while read Path HostNum ID
do
echo "/dev/${ID} <-> ata$(cat $Path/host$HostNum/scsi_host/host$HostNum/unique_id)"
done
</pre>
