5.9 Patrol Read-Related
Controller Properties
You can use the commands in this section to select the settings for Patrol Read. 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.

Read options.
5.9.2 Set Patrol Read Delay Interval Use the command in the following table on the selected controller(s) to set the time
between Patrol Read iterations.

options.

-Val: Sets delay time between Patrol Read iterations. The value is time of
delay in hours. A value of zero means no delay and an immediate restart.
