Disaster Recovery

Manual Disaster Recovery of an HP-UX Client

Use Ignite-UX GUI where it is supported.

Using Custom Installation MediumOverview

Large IT environments often consist of a large number of systems that are based on identical hardware and software. Installation of OS, applications and required patches can be significantly reduced if a complete snapshot of the installed system is used to install other systems. Ignite-UX includes a feature, which allows you to modify parameters like networking or filesystem settings and add software like Data Protector to the image (with Ignite-UX command make_config) before you assign such a Golden Image to another system. This feature can thus be used to recover a system from a disaster.

Creating a “Golden Image”

Steps to Create a The following steps explain how to create a Golden Image of a client

Golden Image system on a target system, which will share the image via NFS to your network. In this example, Data Protector client is already installed on the client system and will be included in the “Golden Image” without additional configuration steps.

1.Copy the /opt/ignite/data/scripts/make_sys_image file from your Ignite-UX Server into a temporary directory on the client system.

2.Run the following command on the client node to create a compressed image of the client on another system: make_sys_image -d <directory of the archive> -n <name of the archive>.gz -s <IP address of the target system>

This command will create a gzipped file depot in the specified directory on the system defined with the –dand -soptions. Make sure that your HP-UX client has granted a passwordless access to the target system (an entry in the .rhosts file with the name of the client system on the target system) otherwise the command will fail.

3.Add the target directory to the /etc/exports directory on the target system and export the directory on the target server (exportfs –av).

4.On the Configuring Ignite-UX server, copy the archive template file
