Re: Dynamic LPAR - Virtual Processors

See I told you it was fun.....

question 1:

It is very complicated. There were some sessions at the last Tech Conference that helped me understand. I cannot seem to find the CD we got so I could send you one.

I think 1.3.12(page 25) has a better explanation.

Hopefully some of this helps,

Bryan,

Thanks for the reply. Here's what the redbook says:

"Although an uncapped logical partition can use more processor power than its assigned
processing capacity, the uncapped logical partition can never use more processing units than
its assigned number of virtual processors."

If I understand that correctly, when the virtual processors and the physical processors are the same it will never use available processors from the shared processor pool. Wouldn't the virtual processors need to be set to a number higher than the physical processors to make use of unused processor capacity?
Also, how does increasing the number of virtual processors affect licensing?
Thanks.
