UNIX for Advanced & Expert Users

Yes and no. In pinciple you are right, but the rootvg might contain things you deem equally confidential - ssh keys in home directories, wallet files for databases, and similar things.

The procedure i described - export the VG, then zero out the first GB of each disk device of the VG - will work for datavgs too, of course. I just mentioned the rootvg, because this is usually the most complicated to delete. You have to "take away the floor you stand on", so to say.

Another option would be to over-install a fresh copy of the OS, so that all the old data get surely overwritten. This can easily be done remotely vin NIM (AIX) or kickstart.

I hope this helps.

Good point, bakunin. I suppose you also have to include the encrypted passwords, which with enough time can be cracked.

If you can wipe a disk with dd then install afresh on that and boot from there, you would then be able to wipe your original rootvg disks too.

Or just destroy the disks, with hammer or some microwaves , if the data on them is more valuable then the hardware
