Ignite backup/restore for migrate from D380 to D280

[Michel Dijkhuizen]

I have a HP9000 D280 production server running hpux 10.20 with oracle 7.3.4 and a HP9000 D380 testserver running hpux 11.0 (32-bits)with oracle 8.1.7 (32-bits).
When we finish our end-user tests we want to migrate from the D380 (test) to the D280 (production). My scenario is to use ignite software to make a full backup on the D380 and restore it on the D280 production server. Is this possible (thinking off difference in hardware, firmware, etc...)and how can i do this? I'm not familiar with Ignite software.

Who can help me ...!

Thanks,
Mies

Hi Michel:

Treat the D280 as if you were going to do a cold-install -- essentially, you are.

Do 'vgexport's of your non-vg00 volume groups with the '-s' and '-m' options and copy the resulting mapfiles to a tape that you can load later. Be very sure to copy all configuration files unique to the D280, too. Certainly, this will include files lke '/etc/passwd', '/etc/group', etc.

Then create an Ignite 'make_tape_recovery' on the D380 with:

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

When you are ready to use it to clone onto to D280, boot from the tape made on the D380. The '-I' option used to make the tape causes an interactive recovery session when you boot.

To begin, on the D280, interrupt the boot process. Select the tape drive that contaains the Ignite tape. Whn asked to "interact with IPL?", answer "NO".

About 10-minutes will epalse before you will see "Recovery tape created from system on ". Press any key to continue.

Choose 'Install HP-UX / Media Only' and select the Advanced Installation tab.

The menus are quite intuitive. You can resize the vg00 filesystems if you desire. On the "System" tab, under "Final System Parameters", shoose "Ask at first boot". This will cause '/sbin/set_parms' to run after the primary installation completes. I find that this is the easiest way to configure networking (including the hostname).

Map files of your (D380) volume groups were captured by the 'make_tape_recovery' process, and included on the tape you created. The Ignite recovery will attempt to 'vgimport' using these specifications. If you have different and/or missing device files as on a different server, then this will "fail". You will see a block-letter "FAILURE" message at the end of the ignition for this reason, but you *will* have a viable vg00. You can review the install.log to confirm this.

You will want to 'vgimport' the D280 volume groups using the mapfiles you first created and held on tape before you used the Ignite tape for installation.

Processing these, and reloading your critical D280 configuration files should yield a viable system again.

Regards!

Hey Mies


It will work , you can try this first just doa install of HPUX 11.00 on the D280 and cgheck for the comtability of versions and bios , and then return to ingnote theere should be no issues.

Hi James,

Thanks for your reaction.

We cannot physically move the discs from the D380 to the D280. As far as i know that is what you have to do when you use vgexport/vgimport. Do you have another scenario.
