Hi,

I have a machine running AIX 4.3.3 which needs to be returned to the
company we hired it from. Problem is that we have sensitive information on
the disks and hence need to clean them.

I'm a little more practiced with Solaris and Linux than AIX, so I went
straight for GNU Wipe - Which fails to compile and looking at questions
other posed AIX 4.3.3 doesn't have have /dev/*random to see the process.

I also tried fwipe, but it can't handle files of this size.

Any advice/suggestions would be greatly appreciated.

It's the same as in the other OS you mentioned, run

dd if=/dev/zero of=<whatever you want to wipe>
dd if=/dev/urandom of=<whatever you want to wipe>

maybe with verying block sizes at least 4 times. That will pretty much
delete everything and prevent it from being restored. If it's about
rootvg disks run the commands from CD in maint mode.

Thanks Patrick - Do you know of somewhere I can obtain /dev/urandom as it
isn't available in this installation?

You may want to try a PPC live cd then, or boot from a recent version
of AIX install CD (AIX 5.2+)
