Thanks to all who replied.
Here is how I wiped the disks..
1. Remove LV and VG information.
2. mediainit the LUN's
3. Created 1 large VG and LV
4. Set a 'while true' loop to echo '1' into a file
5. waited for the LV to be filled up
6. waited some more :)
7. deleted the text file
8. removed LV and VG information
Moving the disks around within the raid unit was also mentioned,
rebuilding the array from the raid unit interface and changing the LUN
sizes.
The consensus seems to be that removing the LV and VG information is
enough to stop 'accidental' data recovery, and mediainit is enough to
prevent all but the most determined. I guess it boils down to how
valuable your data is versus how long it will take someone to recover
that data.
