Ignite across different network segment

[Gordon_3]

Hi all,

From the whitepaper of Ignite Unix, it clearly showed that each network segment require a dedicated Ignite server in order to do the ignite backup. Suppose now I want to consolidate all image files into a single server hard-drive, so it require me to setup those segment ignite server, and then do the ftp to the consolidate one? Or I should have a better method to do so? Thx.

Bgds,

Hi,

You will need to set up a boot helper system to boot and backup across different subnet's

See admin guide !

Or use two network cards in the Ignite Server?

Hi,

For the boot helper system to boot and backup , I do check it out from the admin guide, but seems quite hard to understand. Any solid example that can help?

Hi,

if you want to reinstall a system (it has already a system load), you can just call the bootsys command on the ignite server, e.g.:
bootsys -avf host

If you have to boot from the network you can simply setup a boothelper:

Install the ignite-ux package at your boothelper, then execute for minimal setup:
instl_adm -b # clean default config
instl_adm -t ServerIP # enter address of Igniteserver
instl_adm -m NetMask # enter your netmask, if not default
edit /etc/opt/ignite/instl_boottab and add one or more ip-addresses for temporal use
Maybe you want to setup additional values like default gateway, if your system does not support proxy-arp.

To set up a boot helper, you just need to install the 'Ignite minimum runtime" and do some minor file editing. The minimum runtime is in your distribution, where you drill into the ignite software instead of selecting the entire thing. The minimum runtime is definitely NOT at full blown install. (NOTE: The ignite version on your ignite server must be the same version as your boot helper, or installs that go through the helper will eventually fail. Trust me.)

In the setting up a boot helper doc, after it tells you to install, it gives you a file to edit and point to your ignite server and give a temporary address for the boot helper to boot your new machine to. That is all you need to do. Then when you install on the other subnet, you use 'boot lan.ipoftheboothelper install' instead of 'boot lan.ipoftheigniteserver install".

Sorry I am not more specific, but I am out of town.

Hi Gordon,

You don't need dedicated ignite server on each segment / subnet. You can have one ignite server and setup boot helper for other subnets,

Take a look at this thread,

http://www.software.hp.com/products/IUX/iux_faq

Look at section 6.10 .

Here is another thread,

Hope this helps.

Hi all,

Thx for all your effort, now I seems to able to setup the Ignite server, and able to "Create Network Image across different network segment machine", however, I have one Q about the recover, like those command "bootsys", it require the OS is up and running fine, suppose my system hang and core dump, and then reboot, can I recover the machine in the ISL boot prompt? I checked out the menu, they said press "ESC" at the bootup interrupt prompt

BOOT ADMIN>

I cannot do it as I just get the normal menu which can enter pa, bo... etc. I do try to type "search lan install" at this prompt but no boot device were found... any idea, thx.

Bgds,
Gordon
