Add memory, CPU

Bunti — Wed, 28 Dec 2011 08:28:24 GMT

Hi,

I have a vpar whose resources are heavily busy aslways because of one application Process which are critical. We cant stop that process.

Below are the output of vpar resources.

Could anyone please suggest can i increase resources (memory/CPU) with reference to below information.

Not sure what your vPars version is, so I cannot tell if you can have dynamic memory.

However, the max of CPU count is reached, to increase the max the vPars must be down. Once down, you can increase the max value of CPU and the amount of memory.

Hi,

1.)Yes if you want to do it offline (shutdownt the vpar and add the resoruces and boot the vpar back)

2.) Dynamic CPU - the output is not clear due to page formating, but i guess you have all the 10CPUS available for the VPAR and that is the maxium limit for this vpar at this moment. hence we would need to modify the same which i guess require reboot..

3.) Dynamic Memory - The dynamic memory addition to the VPAR is only supported after 11iv3 hence no chance to look for that here.

Thanks.
