Managing volume efficiency operations manually

You can manage how the efficiency operations run on a volume by running efficiency operations manually.

You can also control how the efficiency operations run based on the following conditions:

  • Use checkpoints or not

  • Run efficiency operations on existing data or only new data

  • Stop efficiency operations if required

You can use the volume efficiency show command with schedule as value for the -fields option to view the schedule assigned to the volumes.

  • Running efficiency operations manually
    You can run efficiency operations manually on a volume by using the volume efficiency start command.
  • Using checkpoints to resume efficiency operation
    The checkpoints are used internally to log the execution process of an efficiency operation. When an efficiency operation is stopped for any reason (such as system halt, system disruption, reboot, or because last efficiency operation failed or stopped) and checkpoint data exists, the efficiency operation can resume from the latest checkpoint file.
  • Running efficiency operations manually on existing data
    You can run the efficiency operations manually on the data that exists in volumes prior to enabling deduplication, data compression, or data compaction. You can run these operations by using the volume efficiency start -scan-old-data command.
