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 that provides a high-speed bi-directional in-band communication between iDRAC and the host operating system through a shared LOM (rack or tower servers), a dedicated NIC (rack, tower, or blade servers), or through the USB NIC. This feature is available for iDRAC Enterprise license.

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 WS-MAN (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 using the XML configuration file through RACADM or WS-MAN 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).

Host operating system and iDRAC are in the same subnet and same VLAN.

Host operating system IP address is configured.

A card that supports OS to iDRAC pass-through capability is installed.

You have Configure privilege.
