Running a Patrol Read

A Patrol Read periodically verifies all sectors of physical disks connected to a controller, including the system reserved area in the RAID configured drives. Patrol Read works for all RAID levels and for all hotspare 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 Operations tab in the right panel, and select Set Patrol Read Properties.
  3. Select an Operation Mode for patrol read. The options are
    • Auto: 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.
    • 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; you can specify a lower number if you wish.
  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, check the box next to it.
  6. (optional) Select Continuous Patroling
  7. Enter the frequency at which the Patrol Read will run, in hour, minutes, and seconds.
  8. Click Go to enable these Patrol Read options.
