| - | ''Continue form 4.5'' | + | ===== Patrol Read Controller Properties ===== |
| + | |||
| + | A Patrol Read scans the system for possible drive errors that could | ||
| + | lead to drive failure, then takes action to correct the errors. | ||
| + | The goal is to protect data integrity by detecting drive failure before the failure can | ||
| + | damage data. The corrective actions depend on the virtual drive | ||
| + | configuration and the type of errors. Patrol Read affects performance; the | ||
| + | more iterations there are, the greater the impact. | ||
| + | |||
| + | ==== Set Patrol Read Options ==== | ||
| + | |||
| + | <code> | ||
| + | MegaCli –AdpPR –Dsbl|EnblAuto|EnblMan|Start|Stop|Info -aN| | ||
| + | -a0,1,2|-aALL | ||
| + | </code> | ||
| + | <code> | ||
| + | -Dsbl: Disables Patrol Read for the selected controller(s). | ||
| + | -EnblAuto: Enables Patrol Read automatically for the selected controller(s). | ||
| + | This means Patrol Read will start automatically after the controller initialization is | ||
| + | complete. | ||
| + | -EnblMan: Enables Patrol Read manually for the selected controller(s). This means | ||
| + | that Patrol Read does not start automatically; it has to be started manually by | ||
| + | selecting the Start command. | ||
| + | -Start: Starts Patrol Read for the selected controller(s). | ||
| + | -Stop: Stops Patrol Read for the selected controller(s). | ||
| + | -Info: Displays the following Patrol Read information for the selected controller(s): | ||
| + | * Patrol Read operation mode | ||
| + | * Patrol Read execution delay value | ||
| + | * Patrol Read status | ||
| + | </code> | ||
| + | |||
| + | ==== Set Patrol Read Delay Interval ==== | ||
| + | Sets the time between Patrol Read iterations. | ||
