Thanks for the feedback. The script only looks in sysfs for controllers
implementing the scsi_host interface. So it won't pick up anything using
the legacy IDE interface. If that's not the case on the first server, I'd
like to see lspci -vvv for the controller in question.
I get no output on my CentOS 5,
kernel-xen-2.6.18-194.8.1.el5.centos.plus, much the same as the
CentOS/RHEL kernel-xen-2.6.18-194.8.1.el5.
Here's my lspci -vvv for my storage/SCSI devices:

find /sys/devices/ -name scsi_host |check_host
This may be the culprit, this find command finds nothing, but I think my
devices still support the sysfs scsi_host interface:
[root@beast ~]# find /sys/devices/ -name scsi_host
[root@beast ~]# find /sys/devices/ -name *scsi_host*

When I change the script to use my find command, I get:
[root@beast ~]# ~john/projects/describe_scsi/describe_scsi

Now I need to find udevadm I guess. It must have been introduced since
the udev version that comes with RHEL/CentOS 5, which is
udev-095-14.21.el5_5.1. rpmfind.net suggests it's only been in since
version 118 or so. Never mind :-)
Cheers,
John.
