Most recent DRD software version:
Dynamic Root Disk version A.3.3.1.223 (January 2009)
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—only on VMs or blades running
HP-UX 11i v3 LVM.
- Perform an OE Update on the clone from an older version of HP-UX 11i v3 (initial release, update 1, update 2,
or update 3) to HP-UX 11i v3 update 4.
DRD is available for download from the HP Software Depot
(DRD product page),
and is supported on HP PA-RISC and Itanium®-based systems.
DRD is supported on systems—including hard partitions (nPars), virtual partitions (vPars), and Integrity
Virtual Machines (Integrity VMs)—running the following operating systems with roots managed by the following
Volume Managers (except as specifically noted above for rehosting):
- Operating System Releases

- HP-UX 11i Version 3 (11.31)
