K.6.1 PPAR DR and CPU Activation Interim Permit


K.6.1 PPAR DR and CPU Activation Interim Permit
A CPU Activation Interim Permit can be used simultaneously with physical partition dynamic reconfiguration (PPAR DR).
Note - While PPAR DR is being executed by the addboard or deleteboard command, at that moment, changing the mode of a CPU Activation Interim Permit will fail. In other words, a conflict between the setinterimpermit command and the addboard/deleteboard command will result in failure of either command.
For example, suppose that you are going to use PPAR DR to add BB#4 to a PPAR for which a CPU Activation Interim Permit is enabled. In this case, all CPU cores in all CPU chips mounted on BB#4 are made available when the addition process of PPAR DR is completed.
However, if the logical domain configuration of this PPAR is not factory-default, you need to use the ldm command of Oracle VM Server for SPARC to incorporate the added CPU cores into logical domains.
Conversely, suppose that you are going to use PPAR DR to delete BB#4 from the PPAR for which a CPU Activation Interim Permit is enabled. In this case, all CPU cores in all CPU chips mounted on BB#4 are automatically deleted from the PPAR as part of the deletion process of PPAR DR. Therefore, you must delete CPU core resources from logical domains in advance before deleting them from the PPAR.
