Could make_recovery tape work on another system?

[Ryan Gu]

I have a RP4440 which has two 73GB HDDs. I want to replace 73GB HDD with 146GB HDD. But we don't want to reinstall the applications.

So, we want to do follow these steps:
1. make a make_recovery tape.
2. after replaced internal HDDs, recovery system by make_recovery tape.

OLD.vg00 2x 73GB HDD
NEW.vg00 2x 146GB HDD

Does it work well?

Hi,

Yup, you can follow the steps above :

1. make a make_tape_recovery
2. shutdown the system
3. replace 2x73GB with 2x146GB
4. boot the system from Ignite/UX tape that has been created on steps #1
5. do the necessary change, especially the boot disk

Hope this information can help you.

Cheers,
AW

Hi Jason,

Yes absolutly, this is one of the reasons ignite is designed.

If you restore your VG00 from tape, choose the advanced settings and you can create larger filesystems for your VG00 volume group.

Don't forget to create a very good backup of the rest of your volume groups.

Hi,

Dont forget to assign the appropriate number of extents (Max PE) to accomodate your larger drive.

Hi,
you can do it by using make_tape_recovery -A,then replace the disks and boot from tape; if you want to enlarge file systems you can by choosing the advanced option.

Hi Jason,

You can proceed as follows:

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

[ Assuming /dev/rmt/0mn you tape device ]


2. Confirm make_tape_recovery completed successfully.

# cat /var/opt/ignite/recovery/latest/recovery.log | grep -i successful

3.
# take backup information of all system configurations. You can run print_manifest or cfg2html or nickel

4.
Also take one tar backup of vg00, being safer side.

5. Backup your other vgs other than vg00.

6.
# shudown -h -y 0

7. Replace the 73GB disks with 146 GB disk.

8. Boot from the Ignite tape.

9. Once recovery done, check and restore the other vgs.

Hope this will help.


Cheers,
Raj.

Jason,

Here is two goodtool , to keep your systems existing config informations:

1. Nickel Script:

2. cfg2html

Both are excellent, generates html file , you can ftp to local windows system and can be viewed, as html format.

I have done it.
The steps I done is blow.
1. do two copies make_recovery tape.
2. shutdown the server.
3. replace the disk from 73GB to 146GB.
4. restart server.
5. boot from tape
my tapes seems cannot bootable, so I boot from CD, and recover from tape.
6. recreate the vg00 mirror.
7. check everything.

other vg, vgdate, had been imported auto.
