install kernel, the RAM file system is still the root disk. For the commands in this phase, the new disk file systems is the root file system. A reboot is required to change the HP-UX kernel root disk from the RAM disk to the final disk.

1.Release RAM disk space to accommodate software installation and kernel build processes to be done later.

2.Load the archive if indicated in the config (for recovery and golden image installation).

3.Update mnttab so it appears to be correct during installation and kernel build.

4.Create device special files.

5.If needed, rename device files to make the I/O configuration appear fully restored.

6.Update bootconf.

7.Change I/O configuration files to match final instance config using ioinit and ioscan -M.

8.Load depot-based software if indicated in the configuration.

9.Save configuration so it is available for reuse.

10.Build final system kernel.

11.Set up the inittab file so final Ignite-UX processing will be done after reboot.

12.Reboot system.

Phase 3

Software is configured and final installation or recovery cleanup is done. The result of this phase is a fully installed or recovered system, ready for use after reboot. If configuration has been deferred, the system will be set up to run FIRST-BOOT set_parms on initial boot so you may choose the hostname, IP address, and other settings. Processing for this phase is done using the final disk-based file system.

1.Update the AUTO boot file.

2.Configure software.

3.Configure final networking.

4.Generate a system manifest.

5.Save the installation information for deferred configuration.

6.Perform final cleanup.

7.Reboot or halt system.

Ignite-UX server requirements

Hardware requirements

An Ignite-UX server supporting boot, installation and recovery for clients requires the following hardware:

•Computer: An HP 9000 (PA-RISC) system running HP-UX 11i v1, HP-UX 11i v2, or HP-UX 11i v3; or an Itanium®-based system running HP-UX 11i v2 or HP-UX 11i v3 is required.

•Memory: Client installation and recovery performance is typically limited by network throughput. Normally, no special consideration for system memory is needed.

•DVD drive: A DVD device is recommended to simplify copying HP-UX release depots directly from installation media to the Ignite-UX server.

•Tape device: As part of your overall disaster recovery plan, you must consider how the Ignite-UX server itself would be recovered. A tape drive allows the Ignite-UX server to use tape media to save the server’s own recovery archive. Note that depots, saved client recovery archives, and other client-specific content typically should not be included in the recovery archive saved to tape. This client content must be saved using backup software. Not all systems support tape boot and so require two-step media recovery. See “Tape recovery with no tape boot support
