Christy,
IF the LPAR is defined with spare processors (reserved), you will be able
to vary the added processors online. Next though, you mentioned '2 CP
engines', are they IFL's or General Purpose processors? Mixing the two? We
only have a z9 and z/VM 5.4. Never tried it.

 Side note......

 We are adding 2 CP engines to our z10 next week. I *believe* we can vary
 these engines onto VM without an IPL.
 Someone very knowledgeable told me he was 99% sure that would work. :-)
 Anyone out there know differently?
 (We currently are using 6 of the existing engines on the box. Our hardware
 folks will 'activate' 2 more....)

 It will be utilized even though you do not define three *virtual* CPUs. CP

 will be able to run three virtual CPUs at once instead of only two.  With
 virtual 2-ways, you ensure that no single guest is using all three CPUs at

 the same time.
