Two cases can happen, as shown in Figure 6-32: 1. You release resources to a level that enables the remaining applications to run at an  optimal level. PowerHA SystemMirror applies the remaining RGs policy to computation  and provides the optimal amount of resources to the remaining applications. 2. You do not release any resources because the level of currently allocated resources is  already under the level that is computed by the  Fit to remaining RGs  policy. Figure 6-32 Resource computation in the releasing process Releasing resources from the LPAR to the CEC DLPAR resources are released by the HMC  chhwres  command. Table 6-24 shows the  commands that PowerHA SystemMirror uses to release resources from the LPAR. You do not  need to run these commands.
