The answers:
many people suggested doing
dd if/dev/random of=/dev/dsk/cXtXdXs2
assuming that the server has /dev/random and slice 2 has not been modified.
some folks suggested Gnu shred.
http://www.gnu.org/software/coreutils/manual/html_node/coreutils_69.html
some folks suggested using Sun's format command; select "analyze" and then
select "purge".

some folks suggested bcwipe or bc.
and of course some folks suggested physical destruction.
Several respondents requested that I not include their name or organization,
so I won't include any. Thanks to everyone for their responses.
