Duplicating the HP Server.

[sunil_4]

I am running an HP9000 server having Os 10.2 and having oracle on top of it. this runs on the K570 m/c.
We have another m/c freshly brought, which is a D390 server. and What we wanted is to duplicate the K570 on the D390 server.
Can i use the tape recovery, in which i will make a image of the K570 server and then recover the new m/c with this tape to duplicate the K570.
If yes How should i go about it?
If no then is there any way out? to make this happen.
Thankyou in advance..
sunil.

Hi,
Ignite/UX may be a good option.

Ignite is a free product from HP. Load it from the Applications CD or download from http://www.software.hp.com (you'll need to search this site to find it)

Ignite has a command 'make_recovery -A' that makes a bootable tape recovery image including all data in the root volume group.

This tape can be booted on the D class box and the interactive menus used to build the D calss system.

There are many other posts in this forum on ignite so you can do a serach on 'ignite' and see lots more info on how to use ignite.

If your oracle DB is in the root volume group (i.e. vg00) tehn make_recovery will back up this too. If this is so then just make sure that Oracle is shut down when creating the image.

Cheers - Trevor

Straight duplication is not an option where the two platforms are very different from a hardware perspective. The Ignite method you may have heard of is not really designed to handle the hardware mismatch either. Your best bet is perform a new install using the install cdroms, add all the desired applications from the install and applications cdroms, install Oracle, and then apply the most recent patch bundle. There are a variety of methods of transferring files across the network to make the machines identical otherwise. The utility I use swear by to do this is rdist.

I am very new to HP-UX. Are you sure the make_recovery works with the HP-Ux 10.2.

Hi,

Regarding Tim's post, yes it is not as straight forward to do and ignite recovery to dissimilar hardware but it is possible and I have seen this used succesfully in disaster recovery when recovering on to a different system. With ignite you do have the option to customise the recovery. The biggest problem will be in lan card and fibre channel and similar card setups if these drivers are not installed on the source system first.

If you are new to HP-UX I would go with Tim's suggestion and do a complete system build and copy the remaining files over the network, or via tape.

Ignite is available for 10.2.

The big hardware compatability issue as I see it is the EISA bus that exists on the D machine and any/all interface cards that attach to it. The K machine that you are extracting the OS from using the Ignite product is not even aware of this issue. As a minimum it will NOT have applicable patches relative to the EISA bus (or anything connected). Not having tried this maneuver I can't say for sure what may occur; will the machine successfully boot after you attempt to load it? Will it be stable afterward? I think the statement that you may end up getting from HP support if you end up with problems is that Ignite is not supported in this situation.

Hi,

I'm afraid that Ignite won't be able to deal with the totally different hardware you have on the 2 platforms.
At the interface levels, D class has an EISA bus of which a K class system has no single idea, to say the least...

I guess that the only valid option is to do a brand new install with the distribution CDROM and apply the same level of patches on the 2 systems. After installation of application software and data transfer, your systems will be 'equivalent' but not 'clone'.

Best regards,

Dan

Hi
Do not go the ignite path as you will encounter many problems. LAN cards, disk paths and kernel config to name but a few - also if you ignite this second server and it is on the same LAN you will have an IP address duplications as it fires up.

Go for the fresh install from scratch and as you are new to Sys Admin use it as a learning situation.


The ignite make_recovery is very highly recommended it is free and will work on 10.20. Once you have finished the system build download it and install.

Hi,
make_recovery wont work between two different hardware platforms as I see it. You would be best off doing a clean install and copying over all the necessary data files.

Thanks for the reply.. i have decided to go with the fresh install. and may be applying the patches.
