Running a Patrol Read A Patrol Read periodically verifies all sectors of physical disks that are connected to a controller, including the system reserved area in the RAID configured drives. Patrol Read works for all RAID levels and for all hot-spare drives. A patrol read is initiated only when the controller is idle for a defined period and has no other background activities. To enable and configure Patrol Read, follow these steps: 1. Click a controller icon in the left panel. 2. Select the Go To -> Controller tab and click Set Patrol Read Properties to display a pop-up window, as shown in Figure 83. Figure 83. Patrol Read Configuration 3. Select an Operation Mode for patrol read. The options are: - Automatic: Patrol Read runs automatically at the time interval you specify on this screen. - Manual: Patrol Read runs only when you manually start it by selecting Start Patrol Read from the controller options screen (see Figure 83). - Disabled: Patrol Read does not run at all. 4. (Optional) Specify a maximum count of physical drives to include in the patrol read. The default number is 255; if you want, you can specify a lower number. 5. (Optional) Select virtual disks on this controller to exclude from the Patrol Read. The existing virtual disks are listed in the gray box. To exclude a virtual disk, select the check box next to it. 6. Enter the Interval at which the Patrol Read will run. 7. If Run Patrol Read non-stop check box is selected, Patrol Read will run continuously. 8. Click OK to enable these Patrol Read options. 132 Intel® RAID Software User's Guide
