Configure an existing ISC DHCP server for SA provisioning

To configure an existing ISC DHCP server, perform the following steps:

  1. Ensure that the configuration file for the existing ISC DHCP server is a copy of configuration file that SA provide, which is located in /etc/opt/opsware/dhcpd/dhcpd.conf.

    The SA DHCP server must not be running on the server hosting the Boot Server.

    • To disable SA DHCP for IPv4, use the dhcpdtool and select the option Disable All DHCP Management option (this preserves the configuration)
    • To disable SA DHCP for IPv6, run the commands:

      /opt/opsware/dhcpd/sbin/dhcpd6tool --no-ra-check disable
      /etc/init.d/opsware-sas stop dhcpd6
    • To delete SA DHCP IPv6 configuration, run the command:

      /opt/opsware/dhcpd/sbin/dhcpd6tool --restart clear

  2. Ensure that the DHCP configuration for systems to be provisioned has all required details, such as the DNS server, netmask, default router, DNS domain, and so forth.

  3. Restart the existing ISC DHCP server.
