Add a new vpar to and existing server running 2 vpars

[Kevin McNamara_1]

I have a server that is currently running 2 vpars (HP-UX 11.23 and VPAR 04.04) on a single npar. We need to create a 3rd vpar. Can someone point me at a procedure to build the 3rd vpar from either an ignite backup or from HP-UX install CD/DVD (cold install).

Hi Kevien:

First you must known if you have hardware for third vpar.(use parstatus and see man page of olrad command,please)

If you have hardware you can clone a server booting new vpar of IUX server in mode interactive for change vital data (hostname,ip...)

Bonsoir Kevin,


That is a subject for wich a detailled answer is almost impossible here : there are many steps to achieve.

May be you could first read those documentations :

- Booting, Installing, Recovery, and Sharing in a vPars Environment from DVD / CDROM / TAPE / Network at http://docs.hp.com/en/5760/vPars_DVD_TAPE_NET_Usage_V2.pdf

- Using Golden Images with Virtual Partitions at http://docs.hp.com/en/6770/golden.images.pdf

And more generally you will find others docs at http://docs.hp.com/en/vse.html#Virtual%20Partitions and http://docs.hp.com/en/oshpux11iv2.html#HP%20Integrity%20Virtual%20Machines

After reading, if something is still not clear maybe, or if you face a problem, you can still post a more precise question.

In a general way you will have to :

- identify the resources you can affect to this new vPar and those you miss. Remember that the granularity is one CPU, on LBA/SLOT. In other word you can't share resources.

- Once hardware has been updated if needed, create your vpar with vparcreate / vparmodify commands. It's rather simple : you say how many cpu, ram you want, witch IO Cards to add, and so on.

- Make an Ignite Image of one vPar you want to clone.

- Modify the Ignite Server so that the new vPar can install with the Ignite image just generated. You can look at "ignite recover one Virtual machine to another" http://forums12.itrc.hp.com/service/forums/questionanswer.do?threadId=1190283. That's for HP VM but it will work also well for any cloning action.

I know it is not a precise answer to your question but I hope it will guide you a little through the process of creating a new vPar.

Regards

The process is the same as when you created the other two.

1) identify unused resources, hbas, disk, cpu, mem for 3rd vPar. ( hopefully you have the ioscan from the origional server before you created the vPars )

2) configure vPar3 using vparcreate commands using the above found resources.

3) use ignite image of 1st or 2nd vPar to clone 3rd vPar

Thanks everyone for your responses. I will study the resources mentioned in the replies. If I still have questions, I will add to this string.
