Patrol read Patrol read
A patrol read periodically verifies all sectors of the drives connected to a controller, including the system reserved area in the RAID
configured drives. You can run a patrol read for all RAID levels and for all spare drives. A patrol read is initiated only when the controller
is idle for a defined period and has no other background activities. You can set the patrol read properties and start the patrol read
operation, or you can start the patrol read without changing the properties.
Access the patrol rate by selecting Set Adjustable Task Rate under the More Actions menu then locating it under the Priority
Percentage column. Enter a number from 1 to 100. The higher the number, the faster the patrol read will occur (and the system I/O rate
might be slower as a result).
