I did another version, with regular expressions to accommodate the
variations. Please give it a shot.
The regular expression doesn't work, here, but the rest of the
script now works on the older server. I replaced the find statement with
find /sys/devices/ -name "scsi_host*" |check_host
and it works.
I also changed the find command again and it also works, with one nit,
which is probably just CentOS/RHEL being odd. See the following output:

Is sg driver loaded?

The various links in sysfs refer to sr0 but I don't have a /dev/sr0, I
have /dev/scd0. I guess that's the udev rules Red Hat chose. Anyway, my
fix was to add 2>/dev/null into the sginfo command, which makes the
warning go away - sginfo -s /dev/scd0 gives me no serial anyway.
The only other improvement would be better formatting for controllers
with multiple devices, e.g. IDE interfaces, port multipliers and real
SCSI cards, which could have 2, 5 or 15 devices attached so displaying
the SCSI device ID could be helpful in those cases. It doesn't apply to
me but I thought of it when someone had both primary and slave devices
on their IDE controller, and someone else mentioned port multipliers.
Cheers,
John.
