9 Zero-touch, bare-metal server provisioning using the Dell EMC iDRAC with Lifecycle Controller Auto Config
2.1.2 DHCP provisioning options
The AutoConfig DHCP Provisioning attribute for an iDRAC can be set to one of four values. This attribute
depends on DHCP configuration and can be set only if it is enabled. The values set for the attribute can be
viewed by using any user privilege level. However, the admin or config iDRAC privileges are required to
enable or disable the attribute.
DHCP provisioning options
Note: The Enable always option is not recommended because it may result in the server being reconfigured at any new
DHCP request, such as an iDRAC reset or introduction of another DHCP server. This option is not supported on iDRAC
2.10.10.10 and later versions of the 13th generation PowerEdge servers.
Default state. In this state, the iDRAC does not request for option 43 from the DHCP server, and
the feature is turned off. Use when not using DHCP for server Auto Config.
Disable
Applies the configuration changes immediately and can be used to configure a server one time
with the Server Configuration Profile referenced by the DHCP server. After the DHCP server
responds with option tag 43, this attribute turns to the Disable state.
Enable once
A state in which option tag 43 is not requested until iDRAC is reset. After iDRAC is reset, this
state changes to Enable once and the configuration changes are immediately applied.
Enable once after
reset
Used to configure iDRAC every time the iDRAC gets an IP address from the DHCP server. The
option tag 43 is requested for every time the server is restarted. When the attribute value is
changed from Disable to Enable always, no immediate action takes place. After the iDRAC is
reset, changes take place immediately. The DHCP Provisioning option remains in the Enable
always state after the changes have been made.
