# Synchronizing logical drives

Note: This action is not supported on the integrated RAID controller.

If auto-synchronization is not supported on your controller, you must use this action to manually synchronize new RAID level-5, 5E, and 50 logical drives after you create them.

If data scrubbing is disabled or your controller firmware does not support data scrubbing, consider manually synchronizing your logical drives weekly using this action.

Manual synchronization can be a lengthy operation. You can synchronize the logical drive immediately or schedule it for a later date and time. You can also schedule the synchronization as a recurring task. A recurring task starts at the initial start time, then runs periodically according to the given interval: the same time each day, each week, or each month.

Note: You cannot perform any other actions on the controller until the manual synchronization is completed. For example, you cannot schedule a synchronization if another logical drive synchronization is in progress.

## An example

You schedule a synchronization task with an initial start time of Sunday, October 13, 2004 at 2:00 AM. It recurs weekly. It will run again on Sunday October 20, 2004 at 2:00 AM.

Note: Do not turn off the server while manual synchronization is in progress.

To synchronize a logical drive:

1. In the Logical devices view, click (logical drive).
2. Right-click Synchronize.
3. Click Yes to synchronize the logical drive immediately (now). Depending on the controller, the ServeRAID Manager displays either a progress indicator in the status bar or (in animation) in the Logical devices view, indicating that the operation is in progress.
4. Or click Schedule to schedule the synchronization for a later date and time. The ServeRAID Manager displays the Synchronization Scheduler pane:
   - From the drop-down lists and calendar display, select the day, month, year, and time you want the task performed.
   - From the Recurring drop-down list, select the interval at which you want the task to recur: Never, Daily, Weekly, Monthly.
   - Click OK to schedule the task; click Cancel to cancel the scheduled task and return to the initial confirmation pane.
