Disaster Recovery

Manual Disaster Recovery of an HP-UX Client

Using System Recovery Tools

Overview

The usage of the system recovery tools, bundled with the Ignite-UX, enables you a fast and easy recovery from a disk failure. The recovery archive of system recovery tools includes only essential HP-UX directories. However, it is possible to include other files and directories (for example, additional volume groups or the Data Protector files and directories) in the archive to speed up the recovery process.

make_tape_recovery creates a bootable recovery (installation) tape, customized for your system and enables you unattended disaster recovery by connecting the backup device directly to the target system and booting the target system from the bootable recovery tape. The backup device has to be locally connected to the client during the creation of the archive and recovery of the client.

make_net_recovery allows you to create a recovery archive over the network onto the Ignite-UX server or any other specified system. The target system can be recovered across subnets after booting ether from a bootable tape created by the Ignite-UX make_boot_tape command or the system boots directly from the Ignite-UX server. Booting directly from the Ignite-UX server can be automated with the Ignite-UX bootsys command or interactively specified on the boot console.

Creating Recovery Archives

The easiest way to create a recovery archive of an HP-UX client is to use the Ignite-UX GUI on the Ignite-UX server. All GUI commands can also be executed from the command line. Refer to the “Ignite-UX Administration Guide” for more information.

Prerequisites Before you are able to prepare your system for disaster, the Ignite-UX fileset has to be installed on the client in order to enable the Ignite-UX server to communicate with the client.

Make sure that the revisions of the Ignite-UX fileset on the Ignite-UX sever and on the client are the same. The simplest way to keep everything consistent is to install Ignite-UX from a depot build on the Ignite-UX server. This depot can be constructed by running the following command on the Ignite-UX server:

pkg_rec_depot -f
