Overview
Dynamic Root Disk (DRD) provides customers the ability to clone an HP-UX system image to an inactive disk, and then:

Perform system maintenance on the clone while their HP-UX 11i system is online
Quickly reboot during off-hours—after the desired changes have been made—significantly reducing system downtime
Utilize the clone for system recovery, if needed
Rehost the clone on another system for testing or provisioning purposes on the following:
Integrity Virtual Machines (Integrity VMs) running either HP-UX 11i v3 or HP-UX 11i v2 LVM
Integrity server blades running HP-UX 11i v3 LVM
Perform an OE Update on the clone from an older version of HP-UX 11i v3 to HP-UX 11i v3 update 4 or later
Automatically synchronize the active image and the clone, eliminating the need to manually update files on the clone
DRD is available for download from this page and is supported on HP PA-RISC and Itanium®-based systems.
