Notes on CPU Activation

Notes on CPU Activation
  1. If the XSCF setting information is initialized by executing the restoredefaults(8) command in XCP 2032 or earlier, the information of the CPU Activation key is also initialized.
    Before executing the restoredefaults(8) command, save the CPU Activation key and then restore the information, or re-register the CPU Activation key.
    In addition, when you replace a CPU memory unit or motherboard, the CPU Activation key may be erased. For details, see "Notes on Maintenance of a CPU Memory Unit, Motherboard Unit, XSCF Unit, PSU Backplane, or Crossbar Backplane Unit."
  2. If you execute the restoredefaults -c xscf command on XCP 2041 or later, the CPU Activation key information is deleted, not only from the XSCF unit but also from the backup information on the XSCF. On the other hand, even if you execute the restoredefaults -c factory command, the information of the CPU Activation key is not deleted.
    To initialize all settings to factory defaults, including the CPU Activation key information, use the -c factory -r activation option.
  3. XSCF setting information saved by the dumpconfig(8) command contains CPU Activation information and CPU Activation keys.
    You can use the restoreconfig(8) command to restore the CPU Activation information and CPU Activation keys that were saved with the dumpconfig(8) command.
    Therefore, if you configure CPU Activation or install a CPU Activation key when configuring settings for the XSCF, such as when configuring an XSCF network or physical partition (PPAR), we recommend that you first save the CPU Activation information and CPU Activation key by using the dumpconfig(8) command. To save and restore only CPU Activation keys, execute the dumpcodactivation(8) and restorecodactivation(8) commands, respectively. Note, however, that CPU Activation information cannot be saved and restored. Use the showcod(8) and setcod(8) commands to reconfigure CPU Activation.
