The document describes how to create multiple clones of a target system disk on HP-UX 11iv3 using Dynamic Root Disk (DRD). It shows creating a first clone on disk5, then a second clone on disk6, both cloning from the original system on disk7. Commands are provided to check the clone status and device mappings. The goal is to demonstrate that previous DRD clones, like disk5, can be reused to create additional clones on new disks.

HP-UX DRD Multiple Copies of Targets
Initial scenario - HP-UX 11iv3 server with four disks.
* Current boot disk is disk7:
disk5 HP 73.4GMAU3073NC
disk6 HP 146 GST3146707LC
disk7 HP 73.4GMAU3073NC
disk9 MSA/P2000 VOLUME
* Initial clone is disk5.
* Then, we create another clone via DRD on disk6.
* The question is: can we use the previous DRD clone disk5? The answer
is: YES!
