Dynamic Root Disk

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.

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.

DRD is supported on systems running HP-UX 11i v2 September 2004, or a more recent release of HP-UX 11i v2, with an LVM managed root volume.
