Re: DOD Disk wiping on AIX & SSA drives...?

I think the DoD standard specifies 7 passes. How about this?

for i in 1 2 3 4 5 6 7
do
cat /dev/random > /dev/hdiskX
cat /dev/zero > /dev/hdiskX
done

When I spoke w/ my IBM AIX-TopGun, he said that he didn't believe that the
SSA-Format
included this option. It will format, but not in the DOD-wipe manner. SSA
drives were
withdrawn prior to the release of this feature.

I opened a ticket w/ IBM AIX Support on this and haven't heard back, yet.

This server (H50) has only 6-4GB and 6-9GB SSA drives to be cleared, but I
have
another server (p660) that has four drawers of SSA drives.
(Both servers contain confidential patient data.)

I have to find a way to "wipe" them and be confident of the process, short
of using a
plasma-cutter...

You can format SSA under diags, just go to Task Selection / SSA Service
Aids.

Also, we format then build new arrays on top of them to help ensure they are
wiped.

Hi all,

I've been searching for options for DOD-Wiping of SSA drives via AIX...

I've found several related threads on the list archive,
(http://unix.derkeiler.com/Mailing-Lists/AIX-L/2005-09/0097.html)

but the "diag -T format" option doesn't work w/ SSA drives and the "scrub"
program doesn't seem to work either.

How about this option?
"cat /dev/urandom > /dev/hdisk1; cat /dev/urandom > /dev/hdisk1; cat
/dev/zero > /dev/hdisk1"

Anyone have any other suggestions?

Regards,
Troy
