Destroying data permanently from old disks
Old box will be returned to HP.
If I only use rm or lvremove/vgremove commmands, how I can be sure that my company data will not be returned from disks?
What would be the most secure way to destroy old data?
Thanks

Stopping short of an acid bath, this recent, lively discussion offers some other choices:

Re: Destroying data permanently from old disks
pvremove will remove the LVM information on the disk ... but if you want to be completely sure, you can use "dd" ...

Re: Destroying data permanently from old disks
If you have a device that is really empty, you could use this trick. Or maybe one of the forum members know how to implememnt /dev/zero?
Goodluck

Re: Destroying data permanently from old disks
To remove all the data from the disk, first remove the lv and then delete the VG's info from the disk and then do a dd to delete all possible data from the disk, say cxtydz
dd if=/dev/null of=/dev/rdsk/cxtydz bs=1024k
Hope this helps.

The thread I cited above...
http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x24b53a7b3682d611abdb0090277a778c,00.html
...contains more information about '/dev/zero'. However, ff you are running 11.11 you should already have /dev/zero. If not, do this to create it:
# mknod /dev/zero c 3 0x000003 #...on 10.20
# mknod /dev/zero c 3 0x000004 #...on 11.x
# chown bin:bin /dev/zero
# chmod 666 /dev/zero

Re: Destroying data permanently from old disks
The *only* SURE way to completely remove data would be to crush & burn 'em.
Seriously, data has been retrieved from disks after up to 17 passes of random overwrites.
IF the pursuer is determined enough, it's only a matter of time & $ - they'll get it.
But normally 3-6 passes of random ones & zeros should be sufficient for most cases. IF you only overwrite w/zeros you may want to up that count some.
Rgds,
Jeff
