Important Information
- MegaPR for Windows requires a minimum level of firmware in order to operate with a PERC controller.

- MegaPR for Windows is only supported on firmware versions listed in the MegaPR Release Notes document or later versions. Do not run MegaPR on controllers with firmware older than the versions listed in the Compatibility/Minimum Requirements section of the MegaPR Release Notes.

- MegaPR will display 'Option not supported for adp 0' for any operations attempted when Patrol Read mode for the controller is set to Disable. The adapter number referenced in the message will correspond to the adapter number specified in the MegaPR command. The Patrol Read mode must be set to Auto or Manual for MegaPR to start or stop a PR iteration. To change the Patrol Read mode on an adapter, enter the PERC BIOS configuration utility by pressing CTRL+M at controller initialization during system POST. Go to Objects, and then select the Adapter menu. If multiple adapters are in the server, select the appropriate adapter. Now choose Patrol Read Options. Change the Patrol Read Mode to Auto or Manual. MegaPR will now be able to start, stop, or display status for Patrol Read from Windows.

- Typing 'megapr ?' displays help information for the MegaPR utility. The example given for command specific help displays '-ctlrInfo ?', which is not a supported option. Supported options include -dispPR, -startPR, and -stopPR.

- For further information concerning the MegaPR utility or the Patrol Read feature, see the latest PERC User's Guide on
