Product details and specifications

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 boot the clone disk during off-hours after the desired changes have been made and significantly reduces the system downtime
  • Utilize the clone for system recovery
  • Rehost the clone of an LVM-managed root on another system for testing or provisioning purposes
  • 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.
