A nice little one liner:
# ls -l /sys/block/sd* | sed 's/.*\(sd.*\) -.*\(host.*\)\/t.*/\2 => \1/'
host0 => sda
host1 => sdb
host6 => sdc
host7 => sdd
host8 => sde
host9 => sdf
therefore
host0 => ata0 => sda
Which is the same with this:
The first number in the [] brackets shows the ata number
# lsscsi --long
