Dynamic Root Disk (DRD) is an HP-UX system administration toolset used to clone an HP-UX system image to an inactive disk for software maintenance and recovery. DRD is available for download from a software depot.

System administrators use DRD to manage system images on HP PA-RISC and Itanium® -based systems.

DRD complements other parts of your total HP solution by reducing system downtime while installing and updating patches and other software.
