booting from an ignite server on different subnet

[uri_1]

hi,
I am very interested in doing this too.
patrick - the link you sent is not working.
isn't there some way to have 'boot lan '
from a different subnet? by setting routing somehow?

Hi,

you need a boot helper system,

Hope this helps.

hey,
i can't find a way to reply.

Say I have a subnet with only 1 hp computer on it, and I want it to be able to boot from an ignite server in another segment, in case of a system disk failure; can I do it someway?

[Sanjay_6]

Hi,

I don't think i understand you clearly. Do you know that you boot using a ignite server to install OS on your local system. If your root disk has failed and you want to reinstall the OS using a ignite server which is across a network or on a different subnet, you need a boot helper.

I hope you are not trying to look for a server from which you can boot and still work as usual as if the root disk has not failed. That is not the purpose of ignite.

I hope i've tried to make sense and have not mistaken what you are trying to do.

Hope this helps.

okay,

i'll be more clear.

i want to use make_net_recovery to make a complete image of vg00 from which I can boot and restore my system if its boot disk is dead for some reason, and I replace it with a new, empty disk.

If I understand corectly, this is done quite easily when the ignite server and the system I want to restore are on a single subnet.

Am I wrong on this ?

However, I have a computer which is found alone on a different segment from the ignite server. And I want some way to boot & start the installation from the recovery image of the server.

Is there some way to do it? Must I have another computer which would help the system to boot?

In this case where you have no option to have a boot helper, you should boot the system using tape OR CD and configure the netowork with IGNITE-UX server's IP. After this you will be able to access the Ignite-UX server.

But with out boot helper system, you can boot from a ignite-UX server which is in different subnet.

Hope the above is clear.
Cheers,

So if i understand, I couldn't do a 'boot lan'. I must boot from the cdrom recovery shell.
If so, I need to setup networking and then what? how do I load the vg00 image onto the client system?

[Manju Kampli]

does your system has TAPE drive .. initially you can boot from the ignite TAPE and then select network installation (here you select your ignite-ux server's IP address as source)

I am not sure, by using bootsys command (which pushes the INSTALL kernel for initial boot of the system can do the job for you. see man page of bootsys command.
