The tools in FreeBSD seem half decent.
The really simple stuff is done by sdd from Ian W. Dall
<ian.dall@dsto.defence.gov.au>. I've got a copy of version 0.1, but I
don't know were I got it from! ;-)
The best tool for this that I've ever run across is scsiping, which
unfortunately only runs on SunOS-4 and 5 to date.
ftp://ftp.cdf.utoronto.ca/pub/jdd/scsiping/
ftp://ftp.fwi.uva.nl/pub/scsiping/
I've appended a sample report from it.
Peek in here for something that can read and write them but not
interpret them:
ftp://ftp.cdf.utoronto.ca/pub/jdd/scsimodepage/
It needs to learn how to use user-mode SCSI commands under NetBSD (only
works on SunOS 4 & 5 right now), but it shouldn't be hard to teach it.
John may even maintain it if he gets the appropriate changes back.
A slightly more SunOS-specific program that prints out other info about
scsi devices:
