Cloning Server

System Dude_1 — Fri, 12 Apr 2002 11:42:25 GMT

I would like to clon a server with a same server model. But the problem is, the new server is having more CPU and memory plus additional external hard disk. For information my current server is connecting to a HA disk and my new server is connecting to XP256. The new server also have a fibre card. Can I use ignite-UX? or make_recovery to do so?

Hi,

Yes you can do, the only thing that you need to do is stop the booting from the tape and interact with it in order to tell it the differences.

Regards,

Justo.

Could you guide me the step. I had never done this before.

Yes you can. If you boot off internal disks that are identical, you COULD make a dd copy and boot off it.
With Ignite you can interact to enter another hostname and IPaddress too.

Hello,

Create your recovery tape using:

# make_tape_recovery -vA -I

This will force the interactive mode when you boot from the tape and allow you to make the changes you need.

Thanks for participating in the forums,

Yes, you can.

Use switch "-I" when you create tape by using make_tape_recovery, then boot from this tape, response the console prompts. See

http://www.docs.hp.com/hpux/onlinedocs/B2355-90749/B2355-90749.html

for step by step details.

One more point, generally, I always make ignite tape twice and put them at different location, just in case something happened. Fyi.

I use ignite, wonderful product.

When you boot from the ignite tape, it gives you the option of continuing with the automatic install or doing a manual install and it waits I think 30 seconds to give you time to respond and then continues automagically.

If the automagic install detects significantly different hardware, then it will drop into the the manual install.

In the manual install, you have the options of changing the disk layout. You can change the directory sizes and placements of all the mount points or even create more mount points for different directories.

Good stuff.

Hi Dude,

Yes you can apply an Ignite-UX.

1. Generate an Ignite Tape by issuing the following command on the configured system ( consider it as S ). The command is :

#make_recovery -A -d /dev/rmt/#mn

The character "#" stand for a number on which the tape drive is connected.

Don't forget the character "n" in the #mn because you are sollicitating the No-Rewind drive.

2. Put your generated Ignite Tape into the desitination server ( D ) and boot your system.

3. On the console, interrupt the boot process by typing any key

4. Reply by YES to the question : Interact with IPL YES/NO ?

5. On the prompt of the ISL, issue the "SEArch" command like :
ISL> SEA

6. Issue the following command :
ISL> BO Pn
Such as the "Pn" stand for the ID of the tape drive giving back by the result of the command "SEA" in point 5.

7. Stop the automatic configuration and modify the specific values for your new system (D) such as :
a. system name
b. TCP/IP address.
c. Default Gateway.
d. Root password.
e. size of files system in root volume group (vg00).
etc...

8. Then OK and your system will be built.

9. Log to your new system (D) and drop the configuration for your the old LVM ( Logical Volume Manager )

10. Configure your new disks XP256 into your LVM.

Attention : After building your server D, when you boot, you will have some errors due that you do not have the external disks as discribe in the Ignite Tape. Don't care about it. You will correct it by steps 9 and 10.

Good luck.

Hi,
Absolutely you can use ignite for your configuration.
Once your machine will be booted first time, it will take the other system component in to consideration.

Thanks,

Hi,

You can use "make_tape_recovery -AvI" and boot from the tape after that follow the install steps. I have done it in the DR testing and it works.

How about to add the new driver for the HBA card as the current server was not install with it whereas in the new server we have it. OR Any driver that differ from the current server with the new server

Re: Cloning Server

Magdi KAMAL — Sat, 13 Apr 2002 06:51:30 GMT

Hi Dude,

Just swinstall the new driver if it is not already installed on your system.
This driver ( or depot ) must be delivered by HP if it is not included in the general patches on your system.

1. Put your installation CD into the drive ( for the drive ).

2. swinstall -i

3. Choose CR-ROM from source depot list

4. Mark it and install

Probably the system will reboot after because this will modify the kernel.

Hi

the driver will not be on the installation CD but on one of the application CD's usually number one.
