Steps to create a IUX from scratch to support network recovery

Lor — Fri, 07 Dec 2007 17:04:08 GMT

Would an expert tell me in details steps to configure an new Ignite-UX server on a HP-UX11.23 server to support network recovery for clients using an image created by another Ignite-UX server.

I am facing situation where an image was created in datacenter1 using Ignite c.7.1.93 and I have to use it in a datacenter2.
Current Ignite server in datacenter1 is not visible to new servers in datacenter2.

My objective is to create a new Ignite server in datacenter2 and ftp trought the network what ever minimal config. file is required.

New Ignite-server in datacenter2 is revision C.7.3.144.

Is my objective realistic and feasible ?
Any help appreciated as I am new to Ignite-UX and have not touched HP-UX for over 3 years.

Is the purpose to use the ignite-server at datacenter2 to image the servers in datacenter1 or simply to replicate the ignite-server at datacenter1 then keep it current with images from datacenter1 ?

If you are simply replicating the ignite-server from datacenter1 then wish to update my first idea would be:

Create ignite tape from ignite-server1 in datacenter1. Use this tape to create ignite-server2 in datacenter2.

After that you can simply replicate the /var/opt/ignite/clients and /var/opt/ignite/recovery/archives directories from ignite-server1 to ignite-server2 to keep things updated.

If you are going to do an actual recovery to a server at datacenter2 you need to beware that Ignite uses the MAC address of the server(s) in it's config. A new server would have a different MAC and would require some slight of hand to make it work.

Thanks for fast reply.
Let me rephrase everything.

Current situation : datacenter1, exists an IUX server. Was used to :
step 1 : create a depot of HPUX11.23
step 2 : a tailored in-house HP-UX OS (with specific security configuration, in-house applications installed,...) image was later on created.
step 3 : tailored image created at step 2 was re-used in datacenter1 to install additionnal HP servers

Objective : "reuse" the tailored in-house OS image created at step2 in remote datacenter2.

My understanding is I have to :
1] create in datacenter2 a distinct Ignite server and
2] transfer through ftp "tailored" image
3] configure datacenter2 new ignite server to be able to use tailored in house OS image.

I have no clue if this is feasible and what the steps are.

note : Only way to tansfer data between sites is a network link.
No access to a tape drive.

Can someone help with detailed instructions ?

1) Install IUX on ignite-server2 using swinstall -s /path/to/ignite_distro( it would be best to keep the same versions of Ignite )
2) ftp /var/opt/ignite/clients/tailored_image_dir from ignite-server1 to same path on ignite-server2
3) ftp /var/opt/ignite/recovery/archives/tailored_image_dir from ignite-server1 to same path on ignite-server2

Note: make sure the ftpd files and dirs are owned by bin:bin. Review the above directory structures from ignite-server1 as example.

Hi Tim,
There is no /var/opt/ignite/recovery directory on ignite-server1.

Its INDEX files contains following lines :

cfg "HP-UX B.11.23 new Standard Archive" {
description "This selection is the new standard for RX3600, 11iV2."
"/opt/ignite/data/Rel_B.11.23/CGIconfig"
"/var/opt/ignite/data/Rel_B.11.23/CGI_archive.cfg"
"/var/opt/ignite/config.local"
}=TRUE

and my understanding is my tailored-image is stored in /images directory :

whmh4476# grep images /var/opt/ignite/data/Rel_B.11.23/CGI_archive.cfg
archive_path = "/images/11iv2PatchKernelHardenUser"

What steps would you recommend ?
