HELP: Ignite_UX Recovery

[Alexander Pino, Sr.]

Dear Friends,

I have an L-2000 server OS = 11.11. A about a week ago I created an Ignite-UX recovery tape (DLT) via the make_recovery command. The command I use is was:

make_recovery -A -C -v -d /dev/rmt/12m -t "ignite_ux 03/26/02 D.R...."

On Monday, 4/1 my staff and I are heading to SunGard (our Disaster Recovery Hot-Site), for a Disastery Recovery test -- Our first test!

What is the process now when we get there? that is, What's the coomand to restore/install this tape? Is there a site I can visit that details how to go about installing the data on this tape unto another server?

Your feedback in very much appreciated!

Regards,

Alex

Hi

Interupt the boot prosess.

At prompt enter:-

# sea

look for path to tape drive p?

enter

# bo alt p? ( path number).


Then follow prompts on screen.

You boot the machine directly off the tape.

I am not sure if this is possible directly off a DLT, but it sure works from a DDS.

Interrupt the boot sequence, then either scan for bootable devices and boot from the one containing your make_recovery tape, or just type in bo [hw path], interact with IPL=N.

What will happen is that it will bring up an HP-UX install window. Then you either leave it to automatically restore the tape contents to your root disk, or you can interrupt it again and change various things, like filesystem sizes etc.

Hi

Points to note:-

The recovery server need to mimic the master in paths to devices, as upon recover the tape will restore the device files from the master and if they do not match then problems will occur.

Hi Steve

Working over Easter??

Hi Paula, yes I am in for a big data conversion/take-on job. Unfortunately Easter is the ideal time to do such tasks, when the rest of the company isn't working.
Muggins here has to change backup tapes at various checkpoint times. :-(
Plus they wanted me to check that the clock going forward one hour didn't upset everything.
Are you working too?

[Paula J Frazer-Campbell]

Hi

Yes I am working in Bromley.

Doing End Of Month accounting procedures, which requires server with no users.

I can think of much better things to do on easter Sunday.

The clocks going forward should have no effect providing that no important Cron jobs are set to run during the one hour jump.

Hi,

As usual Paula has the right end of the story.
One extra link with information:

http://www.software.hp.com/products/IUX/docs.html

Might be usefull.
Really be carefull as Paula already mentioned with recovery on different types of systems with different HW paths.

Succes,
C.

Hi Alexander,

Just to make sure that you have a good set of ignite tape, make a second copy.

To recover using the ignite recovery tape, boot using the ignite tape, interrupt the boot process, boot thru the tape, interrupt the installation (do an interactive installation). you can change the system name, ip address and the filesystem layout if you want. You must do an interactive installation to change these information.

Also i hope you are trying to recover the same class of system using the ignite tape. The hardware configuration should also be same for everything to go smoothly.

Hope this helps.

THANKS! to all of you who have contributed to my question. The Disaster Recovery test was approximately 80% successful. There is a problem/issue with Ignite_UX and OS 11.i -- you all might want to be aware of. Ignite-UX cannot restore any "/etc? directories, so for those of you who have the OmniBack-II software and have a directory: /etc/opt/omni, you will have to rename the directory and later create a symbolic link (or at least that's how I got around that situation). As per HP's Tech. Support, the development team is currently working on this issue.

Thanks again!

Regards,

Alex.

Alexander,

You said this:

...you all might want to be aware of. Ignite-UX cannot restore any "/etc? directories, ...

I've done make recoveries with the "-A" option on "vg00"'s that had over 33GB of data, with countless subdirectories under /etc, and I have successfully restored each one of them countless times.

Are you talking about MOUNTED directories under /etc??? Is your /etc/opt/omni directory really a mounted filesystem? Is /etc/opt/omni part of "vg00"??

Also, you should upgrade your ignite to the latest version and start using make_tape_recovery.

Hi

Harry is correct and providing that the sub dirs of /etc are not mounts then ignite will handle it.

Down load the lastest version and install it - No reboot required and it is free.

The following command will cover all of vg00

- ensure that the device file is correct for your machine.

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

Harry,

perhaps I was not very clear. Yes, Ignite_UX will back-up the /etc directory, even if its mounted (like mine is). It is when you recover from the Ignite_UX tape that an error message appears: "The Volume /etc/opt/omni" is not a suitable mounted Volume (cannot be /sbin, /etc, or /dev in pre-10.20...)

I believe I have the latest Ignite_UX: ver. Ingite-UX-11-11 v. B.3.4.115.


Alex.

[harry d brown jr]

B.3.6 is the latest version.

Check the order of your mounts, you should have the omni directory be a later mount sequence after /etc is mounted.
