First you need an empty disk or LUN (for example c2t0d0), then you basically do

# drd clone -t /dev/dsk/c2t0d0

Now you can for example patch the inactive clone or activate (boot) it by doing a clone activation.

Hope this helps!
Regards
Torsten.

Hi,

Adding to Torsten, you can also create a mirror for the clone with the -x mirror_disk option. This will crete a mirror of the clone. It is an important point to remember that DRD which stands for dynamic root disk is a cloning mechanism that is confined to the root volume group. So basically, this can be done only on the root volume group i.e vg00. The mechanism is present for minimizing downtime for planned and unplanned events.

Hi ...

You also can consider using Make_tape_recovery and disk mirror.
