HP-UX 11i v3 Installation and Update Guide, September 2009 (Update 5 Release)

Part I: Creating an operating system recovery image
To protect your system data, create an operating system (OS) recovery image:
• The Ignite-UX server has two commands you can use to create an OS recovery
image:
— make_net_recovery
◦ Create an OS recovery image and store it on an Ignite-UX server on the
network.
◦ Works on any system that has Ignite-UX installed.
◦ See “Choosing make_net_recovery” (page 28).
— make_tape_recovery
◦ Create an OS recovery image on a bootable recovery tape.
◦ Works on any system that has a local tape drive and Ignite-UX installed.
◦ Also works on any system without an Ignite-UX server.
◦ See “Choosing make_tape_recovery” (page 29).
NOTE: To include the entire contents of the root volume group instead of just a
minimal OS, HP recommends using the-A option to both make_net_recovery and
make_tape_recovery.
• The Dynamic Root Disk (DRD) toolset can also be used to create a clone of the
current root volume group. In the event of a failed upgrade or issues after
cold-installing, you can boot from the clone to quickly recover the system:
— drd clone
◦ Create an OS image on a free local or SAN disk.
◦ Works on any system that has the DRD toolset installed.
◦ See “Choosing drd clone” (page 29).
IMPORTANT: The Ignite-UX recovery tools and DRD toolset are intended to be used
in conjunction with data recovery applications to create a means of total system recovery.
HP recommends against using Ignite-UX or DRD as backup solutions. They should
only be used as part of a recovery or availability strategy.
Choosing make_net_recovery
The Ignite-UX product has the make_net_recovery command to create an OS
recovery image on another system on the network. The image created by
make_net_recovery is specific to the system it was created for and its identity
includes host name, IP address, networking information, and so on. In the event of
root disk failure, you use the Ignite-UX server to restore the system by installing the
OS recovery image.
