+====== MegaraidCLI ======
+**Page Under Construction, is based off of the megaraid pdf on the main page**
+----
+The MegaRaid cli utility is used to talk to LSI MegaRaid controllers, such as the one in the PowerEdge 2950 which is re-branded by Dell as the perc5. The utility exists in the AUR (Arch User Repository) and is installed in /opt.

+===== 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.

+</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.
