Patent ID: 8205207

Claim:
A computer-implementable method for allocating information processing resources among a plurality of logical partitions (LPARs), comprising: allocating a first plurality of information processing system (IPS) hardware resources in a first central processor complex (CPC) to an LPAR; generating a first unique LPAR identifier for said LPAR, said first unique LPAR identifier correlated with said first plurality of IPS hardware resources allocated to said LPAR in said first CPC; migrating said LPAR from said first CPC to a second CPC; allocating a second plurality of IPS hardware resources in a said second CPC to said LPAR; generating a second unique LPAR identifier, said second unique LPAR identifier correlated with said second plurality of IPS hardware resources allocated to said LPAR in said second CPC; providing a notification of the generation of an LPAR configuration change event to an automated resource manager (ARM), said notification comprising said second unique LPAR identifier; and using said ARM to receive said notification of LPAR configuration event and to release said first plurality of IPS hardware resources allocated to said LPAR in said first CPC upon receipt of said notification; using a hardware management console (HMC) to generate said first and second unique LPAR identifiers; using said ARM to reallocate said released first plurality of IPS hardware resources within the first CPC; issuing a query from said ARM to said HMC, upon initiation of said LPAR, to request said first unique LPAR identifier; receiving said first unique LPAR identifier at said ARM in response to said query; storing said first unique LPAR identifier in said ARM for subsequent comparison operations; using said ARM to compare said second unique LPAR identifier to said stored first unique LPAR identifier; and releasing said first plurality of IPS hardware resources in said first CPC if said second unique LPAR identifier does not match said stored first unique LPAR identifier.
