11 Zero-touch, bare-metal server provisioning using the Dell EMC iDRAC with Lifecycle Controller Auto Config
2.1.5 iDRAC interfaces to enable Auto Config
By default, the Auto Config feature is disabled in all servers. However, while ordering, you can request for
enabling this feature by default at the factory settings. If not enabled, you can enable it by using the iDRAC
GUI, RACADM, iDRAC RESTful API, and WS-Man interfaces as discussed in the following sections. You can
also refer to the iDRAC User’s Guide available on the support site and TechCenter.
2.1.6 Enabling Auto Config by using RACADM (local or remote)
RACADM provides the iDRAC.NIC.AutoConfig attribute, which can be modified regardless of the DHCP
setting on the iDRAC.
2.1.7 DHCP provisioning enable setting
This attribute can be set to one of four values (0–3) and is displayed as a definition when queried:
iDRAC.NIC.AutoConfig (Disable/ Enable once/ Enable once after reset/ Enable always)
Description: Set the Auto Config operation.
Possible Values:
 Disabled (0) — iDRAC does not perform DHCP configuration
 Enable once (1) — iDRAC performs DHCP configuration once
 Enable once after reset (2) — Performs configuration after iDRAC is reset
 Enable Always (3) — Always performs configuration
Default: Disabled
Write Privilege: Configure iDRAC
Note: The Enable always option is not recommended because it may result in the server being reconfigured when any
new DHCP request is received, such as an iDRAC reset or introduction of another DHCP server. This option is removed
from iDRAC 2.10.10.10 and later versions, and is no longer supported in the 13
th
generation and later PowerEdge
servers.
 To set Auto Config by using RACADM, run the RACADM get and set sub-commands.
 An example workflow for enabling Auto Config by using RACADM and a remote SSH session to the
iDRAC, and then running the commands from the RACADM command line interface (CLI) is given here.
Note: User inputs are highlighted in blue color in this technical white paper. File names, commands, scripts, and
methods are indicated by using the Courier New font style.
 These commands can also be run from a remote system by using racadm –r <IPAddress> -u
<UserName> –p <Password> preceding the commands highlighted here:
