I'm running FreeBSD 7.2, with Seagate Cheetah (Model ST####) drives.
We are having some problems with the SCSI drives on these machines. Our vendor says that updating the firmware on the drives may fix the problems, and a firmware update did seem to fix some SCSI problems on another FreeBSD host.
How can I view the firmware version of these drives? I tried some tips from nixCraft, but nothing has worked so far. In dmesg, I see the Make and Model, but no firmware revision.
In Linux, this information is often in /var/log/dmesg (Although /var/log/dmesg is sometimes out of date), or I often find this information with something like
sudo lshw -class disk,

Well, turns out I was wrong. Or a little misled. 'dmesg' will show the firmware version, provided that the files at /var/log/dmesg.today and /var/log/dmesg.yesterday haven't been clobbered by the log rotation. I also didn't recognize that '0003' stood for the firmware revision.
# grep -i seagate /var/log/* /var/log/dmesg.today:da2: <SEAGATE ST3300655LC 0003> Fixed Direct Access SCSI-3 device /var/log/dmesg.today:da3: <SEAGATE ST3300655LC 0003> Fixed Direct Access SCSI-3 device
The fields listed here are <"Make" "Model" "Firmware">.
