Caution - Restoring default settings replaces your current configuration changes with the original manufacturer configuration settings. Some of these settings take effect immediately while others take effect after you restart the RAID controllers. Restoring default settings cannot be undone. To restore all defaults: 1. Select Manage > General Config > Restore Defaults. 2. (Optional) To see a list of the current settings and default settings, click See Restore Defaults Changes. When done, click Return to Restore Defaults Page. 3. In the Restore Defaults panel, click Restore Defaults. Changes take effect immediately, except for Requested Loop ID for host ports (one per controller), which requires a controller restart. Select Manage > Restart System > Shut Down/Restart. Enabling and Disabling Background Scrub for Disks You can enable or disable whether the system analyzes disk drives in virtual disks to detect, report, and store information about disk drive defects. At the vdisk level, hard errors, medium errors, and bad block replacements (BBRs) are reported. At the drive level, metadata read errors, SMART events during scrub, bad blocks during scrub, and new drive defects during scrub are reported. Any errors found are reported as events. Background scrub always runs at background utility priority. To enable or disable background scrub: 1. Select Manage > General Config > System Configuration. 2. Set Background Scrub to Enabled or Disabled. The default is Enabled. 3. Click Change System Configuration. Chapter 6 Additional Configuration Functions and Utilities 189
