Dynamic LPAR
Dynamic LPAR is the ability to add or remove resources to a partition while that partition is running. Dynamic LPAR can be controlled from the HMC GUI or through scripts. The scripts are administered with the drmgr command and can be written in any programming language. Alphaworks provide a dynamic LPAR Tool Set for pSeries; refer to the following address for more information:
