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:
- Click a controller icon in the left panel.
- Select the Operations tab in the right panel, and select Set Patrol Read Properties.
- Select an Operation Mode for patrol read. The options are
- (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.
- (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.
- Enter the frequency at which the Patrol Read will run, in seconds.
- Click Go to enable these Patrol Read options.
