Manual Disaster Recovery of an HP-UX ClientManual Disaster Recovery of an HP-UX Client

This chapter explains the procedure that should be used to recover a HP-UX client from a disaster.

The procedure is based on the Ignite-UX product; an application primary developed for HP-UX system installation and configuration tasks, which offers (in addition to a powerful interface for the system administration) preparation and recovery of the system from a disaster.

While Ignite-UX is focused on the disaster recovery of the target client, Data Protector has to be used to restore the user and application data in order to complete the Phase 3 of disaster recovery.

This chapter cannot cover the full functionality of Ignite-UX. For detailed information please refer to the “Ignite-UX Administration Guide”.

Concept

Ignite-UX offers 2 different approaches to prepare a system for and recover a system from a disaster:

Using custom installation medium (Golden Image)

Using system recovery tools (make_tape_recovery, make_net_recovery)

While the usage of Golden Image is most suitable for IT environments with a large number of basically identical hardware configurations and OS releases, the usage of the system recovery tools supports the creation of recovery archives, which are customized for your individual systems.

Both methods allow the creation of bootable installation media like DDS-Tapes or CD’s. Using these media, the system administrator is able to perform a local disaster recovery directly from the system console of the failed client.

In addition, both methods can also be used to run a network based recovery of the client by assigning the failed client a suitable Golden Image or the previously created “recovery archive”. In this case, the client boots directly from the Ignite Server and runs the installation from the assigned depot, which has to be located on a NFS share on your network.
