Wiping data from systems

[Travis Harp]

I have several systems that are going to be changing departments and I need to ensure that all of the file systems are wiped clean.

What would be the most efficient and effective way of going about this?

Hi,

Like this one :-)

# mediainit

or

# dd if=/dev/zero of=/dev/dsk/... bs=1024

Hi,

just 2 days ago I have worked on a similar problem.
I agree with Robert. I choose the second chance. :-)

dd if=/dev/zero of=/dev/dsk/cXtXdX bs=1024

Best regards,
Ettore

Can the dd command be used on a vg or lv?

There are quite a few disks on some of these.

Travis,

Unless you're concerned about data security, I think (since it's within your own company) it might be sufficient to recreate the non-root volume groups and their logical volumes. It would take a substantial amount of effort for someone to discover what had been written there before, and the LVM structures are going to have to be re-created anyway. Unless there are security concerns, I think you're just creating extra and unnecessary work for yourself.

Travis,

And, if you do decide to go the dd route, simply use the raw logical volume.
