I asked:

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.

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.
