Scheduling Automatic Data Scrubbing

You can configure the appliance to perform RAID data scrubbing on a regular basis. During data scrubbing, the appliance reads all the disks in a RAID array and checks for defective blocks, thus reducing the likelihood of silent data corruption and data loss due to bit errors.

By default, automatic scrubbing is performed on a weekly basis for all defined RAID arrays. It can also be run manually for specific arrays, as described in Manually Starting Data Scrubbing.

To schedule automatic data scrubbing for all RAID arrays

1. In the Configuration tab's navigation pane, click Storage > Arrays.

   The Storage > Arrays page appears.

2. Click Scheduled Scrubbing.

   The Data Scrubbing dialog box appears.

   

3. Do one of the following:
   • To disable automatic data scrubbing, clear the Enabling Automatic Scrubbing check box.
   • To enable automatic data scrubbing, select the Enabling Automatic Scrubbing check box.
4. If you enabled scheduled snapshots, do the following:
   1. In the Schedule field, click .

      The Scheduled Scrubbing dialog box appears.

      

   2. In the Start Time drop-down list, select the hour at which data scrubbing should start.
   3. In the On Days drop-down list, select the days on which data scrubbing should be performed. This can be any of the following:
      • One or more specific days
      • Every Day. Data scrubbing will occur every day.
   4. Click OK.
5. Click Finish.
