Section 6: Using Ignite-UX Across
Gateways
A system that is running 9.x or 10.x can use the Ignite-UX server across
a gateway if the target system is booted via the bootsys command. If the
system is booted manually, it will need a helper system to help it boot
across a gateway, and enabling the target system to perform a “boot
lan.<ip_address> install” to the local boot helper system. This section
describes how to configure the boot helper system.
To boot HP-UX across a gateway, you need a system on the local subnet
to provide the target with a minimum core kernel. The helper system can
run either HP-UX 9.x or 10.x. The setup is much simpler if the helper
system is running 10.x.
How to Set Up a 10.x System as a Boot Helper
Step 1: Install the Ignite-UX minimum core functionality onto the helper
system:
# swinstall -s /dev/rmt/0m Ignite-UX.BOOT-KERNEL
Step 2: On the helper, run the following command to point the
INSTALLFS at the correct Ignite-UX server:
# /opt/ignite/bin/instl_adm -t <IUX_server_IP>
Verify that INSTALLFS is referencing the correct Ignite-UX server, and
gateway for your subnet:
# /opt/ignite/bin/instl_adm -d
Step 3: Specify temporary IP address for the helper
On the helper, in the /etc/opt/ignite/instl_boottab file, add the IP
addresses that clients can use to boot. The remote subnet needs to have
temporary IP addresses to use during an initial bootup. These are
located in the /etc/opt/ignite/instl_boottab file, and were provided during
our initial IUX server installation. But, the remote gateway systems
cannot use these, so the boot helper system must supply its own.
Therefore create an /etc/opt/ignite/instl_boottab file on the boot helper
system containing lines of the following format. (See
/etc/opt/ignite/instl_boottab on the IUX server for more details): For
example:
