Follow-up to this; I ended up hooking the AIX drive up to my SGI O2200,
then writing some quick C code to scan raw disk blocks for potential
password entries, which left me with ~370 possible blocks.
Those I then transferred over to a Linux machine (I don't have any PC SCSI
controllers on this side of the Atlantic with which to hook the drive up
directly) and filtered out a lot of false-positives, leaving me with just
five blocks.
At the suggestion of another listmember, I ran a password cracker* on the
remaining data, rather than clearing the passwords and writing raw data
back to the disk (I don't believe that JFS includes anything which would
have detected the change and become upset, but it did make more sense to
just try a cracker first).
* it's a little more involved than that, because of course IBM does things
differently and the shadow file isn't in the normal format, so needs
converting first.
Anyway, all good now (except I may still want to do a clean OS install,
depending on what data's on the machine)
cheers
