Dell PowerEdge RAID Controller 10 User’s Guide PERC H345, H740P, H745, and H840 Series Controllers

Selecting boot mode

1. Enter the Dell PERC 10 Configuration Utility. See Navigating to Dell PERC 10 configuration utility.
2. Click Main Menu > Controller Management > Advanced Controller Properties.
3. In the CONTROLLER PROPERTIES section, select boot mode from the Boot Mode drop-down box.
   The following lists of boot mode options appear:

   Table 1. Boot mode optionsThis table describes the boot mode options.

   Option	Description
   Stop on errors	The system stops during boot for errors which require attention from the user to rectify the issue.
   Pause on errors	System pauses during boot to show errors but continue boot after it times out. Only critical events with an infinite timeout halt boot and require the user’s attention to correct the issue.
   Ignore errors (headless mode)	System ignores most errors during boot in headless mode and prevents the system from halting during boot. Headless mode is designed for systems that do not have a dedicated monitor or a peripheral connected, requiring the user to manage errors during boot. In headless mode, errors can be monitored by viewing PERC events, the life-cycle log, operating system logs, and the system event log. NOTE:In headless mode, any foreign disk is automatically imported during boot.
   Safe mode on errors	System is routed to safe mode when critical errors arise. PERC firmware disables most of the features on the controller, and the controller requires attention from the user to rectify the issue.

   NOTE:In UEFI BIOS mode, errors with timeouts do not appear during boot. It is designed to arise only in legacy BIOS mode.

   NOTE:By default, the boot mode option is set to pause on errors.
4. Click Apply Changes.
   The boot mode operation is completed successfully.
