To wipe the image off of the disk, you can just 'dd' over the disk.

# dd if=/dev/null of=/dev/rdisk/disk6 bs=8192

Once that finishes there will be nothing left on that device.

To remove the disk from the 'drd status' output you can remove the file /var/opt/drd/registry/registry.xml

The file should get recreated the next time you run a 'drd clone' operation.
