Ignite and Disaster Recovery

[MikeL_4]

We are currently using make_net_recovery to make archives for our production servers. In
a Disaster Recovery case however we would not be recovering the Ignite server where the archives are stored.

* Archiving contents of server1 via tar to
/var/opt/ignite/recovery/arch_mnt/2004-12-04,04:00

Is there a way to take this archive and create a bootable CD from it ?? None of our servers have tape drives attached to them that we could use the make_boot_tape option, but if I could create a CD using my writable CDROM on my PC we could you that in a recovery mode.

Mike,

Take a look at Chapter 8 in the "Ignite-UX Administration Guide":

http://www.docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B2355-90849/B2355-90849_top.html&con=/hpux/onlinedocs/B2355-90849/00/00/1-con.html&toc=/hpux/onlinedocs/B2355-90849/00/00/1-toc.html&searchterms=Ignite-UX%20Administration%20Guide&queryid=20041209-082348

It talks about creating your own installation media.

The way make_net_recovery works the following plan makes sense:

Designate a server as the image server. Make sure those images get backed up along with the configuration of that server. You can use ignite or an ignite/fbackup combination.

Then to recover the Enterprise the steps are as follows:

1) Rebuild the ignite image/recovery storage server.
2) Boot the newly designated servers off the ignite/recovery server and load the make_net_recovery images.

Note that make_net_recovery images are server specific. Hostname server1.your.net can only be rebuilt off its own archive.

There is more flexibility but more post configuration work with Golden images.

Hi Mike,

Normally the way we do this or plan this would be,

designate a server as ignite dr server. recover the server with a ignite image from the ignite server. Then restore the backup data containing the ignite image for all the server that was backed up from the ignite server.

It is okay to create a cd for a server or two, but what if you have to do this for a few hundreds of them.

This procedure from itrc might help you a little on how to create a bootable cd for a ignite image,

The itrc doc id is KBRC00002082.

Never tried this myself. Too painful for me.

Hope this helps.

Thanks, I agree recover the Ignite server and go from there, and in a real disaster that is what would happen, but this is a HOT Site exercise and it cost $'s to add another server to the mix just to recover the OS and not need it any more.... thus the need to make a CD to use in it's place..
