can I ignite hpux11.11 os from one system to another using tape?

[Sammy_2]

1) Need to make a DRP server to look exactly like PROD server. Can I make_tape_recovery on PROD server and restore to DRP box without any issues.? Since H/W specs are different (see below) btw 2 boxes, is that going to be a problem ?



PROD SERVER SPECS
===================
HP 9000/RP4440
24gb mem, 8 CPU, 4 network ports, HPUx 11.11
==============

DRP SERVER SPECS
===================
HP 9000/K580
4 gb, 4 cpu, 1 network port, NO OS right now


2) If above method not recommended, How I can just copy kernel parameters from one server to another so when I look thru SAM on both servers, they look exactly the same. Will copying /stand/system do the trick and rebooting.

Hi Sammy.
I do not have a definitive answer for you but I can tell you that I have successfully "cloned" systems with comparable ( i.e. rp3440 to rp 3410 )hardware using this method.

One word of caution. If your prod server uses any kind of cluster software you might want to start the "cloned" machine while it is diconnected from the network for the first boot. A clone trying to join a prod cluster can be a bad thing.

Sammy,

To your first question, the answer is no, since both machines are so different, probably after you restore the OS, if you ever get that far, the machine is just going to post and boot with a lot of errors.

Regards,

Jaime.

hi

In ignite , you can specify to restore on different hardware

When you execute ignite , do advanced option and specify restore on different hardware platform.

Interrupt the boot , sea for find random access media (tape), bo Px

Ignite screen will be appears, select install HPUX,select advanced installation

here, servers are very different, and I don't know if restore will be works correctly....

I've done it, but only on identical hardware.

Be aware, the IP address may be duplicate if the system the tape came from is online.

You may have to do an interactive ignite and change where your root data will reside.

I wouldn't do it on 2 different type servers.

[Rick Garland]

Odds are - NO. HW is vastly different.

Many changes from a K box to RP box. You can try (as this will be definitive answer).

[DCE]

Ignite *might* work, if you specify the cloning to hew hardware, as mentioned above. This equipment is quite disparate, and the chances of success are small.

You might have better luck creating an ignite golden image and using that to do the system creation (it is less hardware dependent)

A word of caution on kernel parameters, you are going from a 98 cpu 24 GB memory PCI bus system to a 4 cpu 4 GB memory HSC bus system - it is doubltful that ALL of the kernel parameters will be identical.

[Sammy_2]

I am convinced igniting is not a good idea. So, How about installing OS/patches and but then how can I copy ALL kernel parameters to other system rather than doing manually (one by one) thru SAM. Not sure copying /stand/system file from PROD and rebooting will work.

I want a visual look at SAM on DRP to look like the one on PROD.

[Sammy_2]

I know not all kernel params will be same due to disparity in hw/memory. But the ones (kernel parameters) that are not Hwdependent , how can I copy those ?

[Ludovic Derlyn]

for me , it's more appropiate to define parameters in function of preconiosations constructor
(sorry if my english is not very good)

[DCE · Accepted solution]

after you have the initial OS install and patching done, open a window to the production server, and a window to the test server. using cut and paste in conjunction with vi, you should able to block copy the /stand/system parameters you want from the production system to the test system.

you might want to copy your working kerel to a new name, in case you have to boot from it if the ystem will not boot from the new kernel

[Sammy_2]

Thanks to all. Especially to DCE who answered both of my questions. I will redo OS/fs and then copy kernel parms from prod to drp.
