"Expert" Recovery

The first method, "expert recovery" (formerly called Support Media Recovery), allows you to recover a slightly damaged root disk or root volume group. With this method, you boot a special recovery system from core HP media. Once the recovery system has been booted, it allows you to do the following:

Note that expert recovery does not require that you do any preparation before you use it. The media used is supplied by HP; it is not customized to your site. Of course, this also means that any customizations you have are not reflected in the files you recover via expert recovery. Expert recovery is meant to give you enough capabilities to get your system back up again. At that point, you need to use your normal restore tool to recover your system to the state it was in before the problem occurred.

System Recovery

The second method uses the make_recovery tool, which is part of the Ignite-UX tool set, and is delivered on the Applications disk with Ignite-UX. The make_recovery tool allows you to use tape media to quickly recover from a failed disk (root disk or disk in the root volume group). The failure can be either a hardware failure or a catastrophic software failure.

System recovery does require some work on your part before the problem occurs. On a regular basis, you need to run the make_recovery tool on each of your systems. This tool creates a bootable recovery (install) tape which is customized for your machine. The tape contains your system's configuration information (disk layout, etc) as well as an archive of the files on your root disk or root volume group. (You can exert some control over which files are saved as part of the archive.)

When you have a failure, follow these steps:
