12.10.7 Changing the Expander Minimum Scan Duration Settings

Some expanders do not scan the drives on time for the firmware to discover them. Once the controller is up, the logical device may be marked as failed. To overcome this situation, the firmware has added a new configurable value of minimum scan duration (in seconds) that will force the firmware to stop and wait during discovery.

Whenever the Expander Scan Duration value is changed, it will take affect on the next power cycle. The controller waits for the specified duration and then scans/discovers the drive attached to the expander.

To change the expander minimum scan duration settings:

  1. In the Enterprise View, select a controller.
  2. On the ribbon, in the Controller group, click Set Properties.
    The General tab on the Set Properties window opens.
  3. To specify the waiting time for the controller, slide through the bar next to the Expander Minimum Scan Duration field.
    When the Expander Minimum Scan Duration setting is changed, the power cycle warning is displayed.
  4. Click OK.
    The value of Expander Scan Duration gets displayed in the Properties tab of the controller.
