The options window, Figure 6-28, is used to specify what resources should be
added or removed from the partition at the programmed time. In this example, 0.4
processing units will be moved from the partition VIO_client2 to the partition
VIO_client1. Click the Save button, which adds this task to the list of
programmed operations.

Important: If you schedule a periodic dynamic LPAR reconfiguration, as in
this example, then you must program other reconfiguration operations to move
the same amount of resources into or out of the partition; otherwise, there will
inevitably be eventual depletion of resources.
The operation to start up or shut down a partition is similar to that for the
reconfiguration.
6.3.2 PLM policy reconfiguration
To periodically change the PLM policy file, you must use the PLM command line
interface with a scheduler, such as the AIX 5L cron or at commands. Use the
xlplm -M command, as shown in the “Modify a PLM server” on page 412. Refer
to the AIX 5L documentation for information about the cron and at commands.
