I'm pretty worried if IBM are withdrawing processor activations for some of the models. What this means is that if you have, for example 13 processors activated out of 16, that come 1st July, even though you have the processors physically present in your system, you will never be able to use them.
Call me a cynic, but this looks like a move designed either to make sure that customers activate (and pay for) un-needed processors before they are required (a money grab), or after 1st July, that they are forced to upgrade to new hardware before they actually exceed the capabilities of their existing stuff.
And as far as IBM is concerned, it costs almost nothing apart from the cost of collecting the payment to activate a processor. Maybe there is scope for working out how to jailbreak processors on IBM tin.
Must remain anonymous, as IBM currently pays me (at least, indirectly).
