Ignite-UX Administration Guide for HP-UX 11i (B3921-90079, October 2013)

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 should 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 should be saved using backup software. Not all
systems support tape boot and so require two-step media recovery. See “Tape Recovery With
