I just built an ignite server. Built it but not real schooled at using it yet. I ran a 'create network recovery' and it created a file on my server. Now, If I blow away the client side OS, for a test, how can I use the ignite server to recover the client system if the network configuration is blown away on the client? Not sure how this works. Can someone explain?

You will need to install a 'base OS' on the client - complete with all the network setup. Then after you have that you can add the server as a client and ignite it.

Hello,

Create a boot tape from your server using : make_boot_tape.
Then boot your client from this tape. It will load everything usefull to get the image on the server.

We use ignite for tape creation and recovery. I am trying to do this over the network. I have a server 'a' and a client 'b'. I'd like to recover 'b' from 'a' accross the network. Is this possible. I thought that is what the ignite server was all about.

That will be the end result - but you still need to have something on the server to be recovered in order for the ignite server to see and recognize it

Hello Robert:

I recommend the following document:

ITRC :: navigate knowledge trees and response center FAQs :: HP-UX Software Recovery Handbook :: Ignite-UX

Part "Booting and Installing an HP-UX Client".

This will give you a very short overview over the recovery options within IUX.

Hope that helps,
Johannes

You can install a base OS on your target server and use the ignite server to push an image onto the target server.

You can also do a pull from the client, once its running HP-UX.

It seems from your message, you've got your profile INDEX file ready to go. Thats where you do customization, set the IP address of the target server etc.

You make a golden image with the following command.

/usr/contrib/bin/make_sys_image -d /images -s local -u

-d is for the directory where you want the image to go.

Note that this process changes the /etc/group file and others while building the image.

It is best to shut down oracle while building an image. The database and sqlplus will malfunction if you try operations during a goldem image build.

To recover a failed disk or volume group using the system recovery
archive:

1. Boot the failed system. This can be done in one of
the following ways:

* Using the client console, after booting
with "boot lan install";

* Booting from an Ignite-UX server, using bootsys(1m),
if the client OS is running;

* Booting the failed client locally by using
a boot tape previously created with make_boot_tape(1m). the first option is the one I'd try in this instance

2. Do not interact with ISL.

3. Select: [ Install HP-UX ], from the main menu.

At the client:

1) Respond to Network configuration dialogue
screen.

2) Respond to the UI display options (to run at
Server or at Client).

3) If working from the Ignite-UX server, select
the client icon for the system to be recovered.

4. Choose "Install/New Install".

5. Select the recovery configuration to use.In your case it sounds like this maybe your only available option ....

I'd check out the available documentation that comes with ignite & on the hp.docs site too they are not too bad.

Hi,

In fact the tape generated with make_boot_tape contains all necessary to install the server B using the network (ignite + network configuration) but the install will use the networked image stored on server A.

Hi,

since you have removed OS on client, you can pull the OS from ignite server

>to pull from ignite server
.get into main menu (by pressing any key within 10 sec while booting)
main menu> boot lan. install

this will install the OS on client
