Nice.
Output on one of my machines is however not as expected:

host3: [Empty]
This machine has seven SATA ports: one provided by the JMicron chip, the other six by the Intel H55 south bridge. Only three ports are currently used, but I had expected another [Empty] entry.
Here's what's in /sys/devices:
root@zotac:~# find /sys/devices/ -name scsi_host
/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/host4/scsi_host
/sys/devices/pci0000:00/0000:00:1f.2/host0/scsi_host
/sys/devices/pci0000:00/0000:00:1f.2/host1/scsi_host
/sys/devices/pci0000:00/0000:00:1f.5/host2/scsi_host
/sys/devices/pci0000:00/0000:00:1f.5/host3/scsi_host
Not sure what to make of that...
I'm guessing it's an artifact of IDE compatibility mode. You can see host1
reports two drives, and my script is only expecting one. Master vs. slave
emulation, perhaps? Can you check your BIOS for legacy IDE vs. AHCI mode
setting?
I suspect my script will have similar problems with port multipliers.

Can someone running near to Linux 2.6.30.6 or slightly less post
(privately) their .config file so I can see what option I am missing as I
definately have scsi devices & hosts , But there are no 'scsi_host' entries in
the /sys file system .
