HP Insight Control Server Provisioning 7.2 Update 2 Installation Guide

• You already have a DHCP server on your network
• You require more advanced features than you can configure using the appliance UI.
NOTE: The appliance TFTP server required to allow target servers to PXE boot from the appliance
will always run regardless of whether the DHCP server you use is internal or external to the
appliance.
Setting up a DHCP server external to the appliance
The Insight Control server provisioning appliance can support either using the DHCP server internal
to the appliance, or using an external DHCP server set up at your facility.
If you require more control or more features from your DHCP server than are available via the
appliance UI, you should disable the DHCP server on the appliance and configure your own server.
See “Deciding whether to use a DHCP server internal or external to the appliance” (page 34) for
details.
Use the following instructions for configuring an external Windows DHCP server or an external
Linux ISC DHCP server (the Internet Systems Consortium implementation of DHCP that is distributed
with most major Linux operating systems).
NOTE: HP recommends setting the lease time on your DHCP server to at least one day to prevent
issues caused by time synchronization.
NOTE: These instructions are for configuring the extended DHCP options required for PXE booting
target servers from the appliance. If you do not require extended options, no special configuration
of your DHCP server is necessary beyond the ability to provide an IP address to target servers and
possibly extending the lease time.
NOTE: If you decide to use an external DHCP server, make sure Service provided by appliance
is set to None on the appliance Settings DHCP screen.
NOTE: You can find the deployment IP address on the Settings Appliance screen under Deployment
IP.
To set up an external Windows DHCP server:
1. Using the server manager, add a DHCP server role on your Windows system.
2. Set up your scope and start the server. Be sure to set the lease time to one day or greater.
3. Right-click on IPv4 and select Set Predefined Options... From that screen, you can add the
following options to your DHCP server IPv4 global settings:
Data typeOption nameCode
IP Addressbuildmgr_ip186
Wordbuildmgr_port187
4. In your DHCP scope, right-click on Scope Options and select Configure Options.. to assign
the following values to the DHCP options:
Option valueOption nameOption number
