Obsolescence
HP-UX 11i v3 has native support for multi-pathing and the features provided by this
product will be part of the base OS. Therefore this product will be discontinued for future
releases of HP-UX.
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.
Summary of Change
In June 2007, DRD is newly added to the HP-UX 11i v2 Operating Environments. It was
previously released on the Web in January 2007.
