 The B<--commit> flag is used to write the contents of the temporary side of the flash to the permanent side.  This flag should be used after updating code and verifying correct system operation.  The B<--recover> flag is used to write the permanent side of the flash chip back to the temporary side.  This flag should be used to recover from a corrupt flash operation, so that the previously running code can be restored.
 
-B<NOTE:>At present, the B<rflash> command B<doesn't> support B<commit/recover> for BPAs. Because the command "B<licutil>" on HMC doesn't support the "B<commit>" and "B<recover>" operation for the BPA. And "B<rflash>" is dependent on the "B<licutil>" command. So when the B<--commit> or B<--recover> two flags is used, the noderange cannot be a BPA or BPA list in the B<rflash> command. xCAT will pay the attention to the changes all the time.
