Hi Gurus,

wondering if someone can help me in how to make an OS image by using the Ignite software.

Regards

Hi Alex,

How about the make_sys_image command.

I'd start by reviewing some of the docs at this URL

http://www.docs.hp.com/en/IUX/infolib.html

What's the scope of the ignite backups you're wanting in your environment>

1. Do you just want to ignite a single server locally?

2. Or copy the OS of several servers to one central Ignite server?

Hi Alex:

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

This will create a bootable tape backup image of vg00. See the manpages for more information.

Regards!

The make_sys_image command create an image of the vg00 to the default tape device (typically /dev/rmt/0m)

Depending on your configuration, you may want to include other volume groups.

Do a man make_sys_image to see the many options available

Hi,

The scope of this question is to have a good copy of the current configuration of a server. An HP engineer recommended me to use the ingnite software but if some of you has a better suggets, I will really appreciate it. In the James response, I suppose I can repeat the command for each VG or include all of them in just one line.
is this correct?

Regards

Ignite is designed to create a bootable archive, to tape or network, of the operating system ONLY. It is NOT designed to be used as a general backup tool.

YOu should use Ignite to create bootable backups of your OS and another tool to do regular backups of your data.

I try to keep HP-UX on VG00 and data on other VGs. That way if VG00 blows up, I can recover it and still have the other data available.

My preferred method is to create tapes via the command:

# make_tape_recovery -a /dev/rmt/?mn -I -v -m tar -x inc_entire=vg00

Thanks Patrick for the explanation, indeed, I am using another tool for regular backups (netbackup). So, just making a vg00 backup to use just in case, is ok for me.

Best regards

Hi,

Even if you do not have any other mode of backup, taking non-root VG backups using ignite is not worth useful unless it is taken when the files are not is use. Which is not the case most of the time.

So it will be always safe to backup your root using ignite and other VGs using proper application supported backup tool. The best reason supporting this will be that there is a rare possibility of both root and other VG's getting corrupted simultaneously. So while recovering, there is no point in recoverying both root and other VG's when there was problem in only one VG either roor or other. This will delay the recovery depending upon the volume of data.

HTH,
Devender
