Hi

I'm trying to find a way to change a lpar from capped to uncapped on a regularly time basis. In the HMC GUI, there's the possibility to schedule dlpar operations, but I can't find a capped/uncapped option. I was thinking of the command line -dynamically changing the sharing mode is possible with the chhwres command-, but access to the crontab is not allowed because of the restricted shell of hscroot.

Any ideas? Thanks....

I'm pretty sure you can't changed from capped to uncapped without stopping the profile and restarting.

You can (I believe) configure profiles as uncapped with a weighting of 0, this makes them behave as if they're capped. You can then dynamically change the weighting at a later stage, although I've no idea if you can schedule that.

Weird? When did we lose our ability to edit our own posts?

Anyway, you could, at a push if you find your command does work (I don't think it does) schedule it from a remote host using ssh to the HMC assuming you've configured remote ssh access previously.

Actually you can change the capped/uncapped setting using the DLPAR->Processor->Add or Remove task, or using the command line using the chsyscfg command. The attribute is called sharing_mode, man chsyscfg will show you the values you can set it too.

And as Tony mentioned this could be automated by setting up a cron job on another system, that can ssh to the HMC.

Have a look at the following website for some examples about using the HMC command line:

Actually, I used the chhwres command which is, I think, more appropriate for dlpar operations. Thanks for the hint with the remote ssh command execution. I will try that, although I still would prefer something located directly on the HMC.

You are right, it should be chhwres for DLPAR operations, chsyscfg would only change the partition profile.

I wonder what the hell I was remembering then.

Oh well.

I think you couldn't change uncapped to capped and vice versa with the initially releases, but it does work now.

Ah good, I'm happier just being out of date than just plain wrong

Hi Tony,

You asked about the ability to edit posts. I checked with the server team and this feature has been temporarily disabled. It should be reinstated shortly.

Thanks Nicolette
