Setting first boot device using RACADM
● To set the first boot device, use the iDRAC.ServerBoot.FirstBootDevice object.
● To enable boot once for a device, use the iDRAC.ServerBoot.BootOnce object.
For more information about these objects, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
Setting first boot device using virtual console
You can select the device to boot from as the server is being viewed in the Virtual Console viewer before the server runs
through its boot-up sequence. Boot-once is supported by all devices listed in Setting first boot device on page 102.
To set the first boot device using Virtual Console:
1. Launch Virtual Console.
2. In the Virtual Console Viewer, from the Next Boot menu, set the required device as the first boot device.
Enabling last crash screen
To troubleshoot the cause of a crash on the managed system, you can capture the system crash image using iDRAC.

For information about Server Administrator, see the OpenManage Installation Guide available at https://

The host system should have Windows Operating system to use this feature.
NOTE:
● This feature is not applicable on Linux system.
● This feature is independent of any agents or attributes.
Enabling or disabling OS to iDRAC Pass-through
In servers that have Network Daughter Card (NDC) or embedded LAN On Motherboard (LOM) devices, you can enable the OS
to iDRAC Pass-through feature. This feature provides a high-speed bi-directional in-band communication between iDRAC and
the host operating system through a shared LOM, a dedicated NIC, or through the USB NIC. This feature is available for iDRAC
Enterprise license.
NOTE:
iDRAC Service Module (iSM) provides more features for managing iDRAC through the operating system. For more
information, see the iDRAC Service Module User's Guide available at www.dell.com/idracservicemodule.
When enabled through dedicated NIC, you can launch the browser in the host operating system and then access the iDRAC
Web interface. The dedicated NIC for the blade servers is through the Chassis Management Controller.
Switching between dedicated NIC or shared LOM does not require a reboot or reset of the host operating system or iDRAC.
You can enable this channel using:
● iDRAC web interface
● RACADM or WSMan (post operating system environment)
● iDRAC Settings utility (pre-operating system environment)
If the network configuration is changed through iDRAC Web interface, you must wait for at least 10 seconds before enabling OS
to iDRAC Pass-through.
If you are configuring the server using a Server Configuration Profile through RACADM, WSMan or Redfish and if the network
settings are changed in this file, then you must wait for 15 seconds to either enable OS to iDRAC Pass-through feature or set
the OS Host IP address.
Before enabling OS to iDRAC Pass-through, make sure that:
● iDRAC is configured to use dedicated NIC or shared mode (that is, NIC selection is assigned to one of the LOMs).
