| enabled=? | Starts or stops the LUN DIF scan. | The value can be "start" or "stop". |
| lun_id=? | LUN ID. | To obtain the value, run the "show lun general" command without parameters. The value ranges from 0 to 65535. |
| lba=? | Start LBA of the LUN DIF scan. | The maximum value cannot exceed the maximum capacity of the LUN. The value ranges from 0 to 549755813887. |
| length=? | Length of the LUN DIF scan. | The maximum value cannot exceed the maximum capacity of the LUN. The value ranges from 1 to 549755813888. |
| controller=? | ID of a controller. | To obtain the value, run "show controller general". The value is in the format of "XA", "XB", "XC" or "XD", where the "X" is an integer ranging from 0 to 3. |

If parameter "controller=?" is set to the default value, this command is applicable only to the current controller. If parameter "controller=?" is specified, this command takes effect only on the specified controller.
Example
-
Start the DIF scan task for all LUNs of disk domain "0" on controller 0A. The scan covers 100 sectors whose start LBA is "0".

-
Start the DIF scan task for LUN "0" on the current controller.
