adding cells to a Vpar

Todd McDaniel_1 — Wed, 05 Apr 2006 15:34:16 GMT

I am fairly new to adding cells to a Npartition and then to a Vpar. Can yall give me some guidance as to how I go about adding the new cells to the Vpar portion. I believe I have the correct command to add them to their respective Npars first.

I have a question about the CLM value... Is there a default value is that is set for partitions? 50% was in the man page. i dont recall using it the last time we added a cell to an Npar. i dont believe I need to configure it as the CLM value is probably already set for the Npar. Can I just leave that last field blank where the CLM value is?

Server1
parmodify -p 4 -a 0/7:base:y:ri:50% -B

Server2
parmodify -p 5 -a 1/7:base:y:ri:50% -B

Once I get this far, I know how to vparmodify and get the CPUs into the 2 Vpars but Im not sure how to add the 16gb memory to each Vpar. How do I ensure I add the cells properly to the 2 Vpars and get the proper amount of memory in each Vpar?

All help is greatly appreciated.

Once the cell is added to the npar, just shutdown the vPar and use vparmodify to add the memory. What system you are using?

well CLM is only valid with certain HP-UX versions and certain processor types.

Also, as far as the Vpar chanegs are concerned, do you wiosh to add the full cell to each Vpar?
If so, if using A.04.0x you can add entire cells to a Vpar (check Release Notes for the version you are using)

Hi Todd,

You add to do it in two steps. This can't be done while the server is up, so you have to shutdown one to modify it from the other and after reverse. To add memory :

vparmodify -p -m mem::TotalSize

vparstatus -A (To display all available ressources)

vparstatus -v -p (Display information about vpar)

I've done this few week ago and that's all.
Once the server is up, the memory is available.

If you have two cells in your Npars you must spread all your DIMM accross the two cells. What I mean is that you can't have 12Go on one and 20 one the other, you should have on both 16Go. For the repartition just be careful, if you SD is an orca(PA8800,PA8900) or not(PA8700).

Hope this helps
