Booting a Red Hat Enterprise Linux server in a non-DHCP environment

If you plan to use SA Provisioning in an environment without a DHCP server, you must assign static IP information for the managed server and manually configure that server to resolve the SA Core.

There are several reasons you might need to manually specify the network information for a sever being provisioned:

  • You don’t use DHCP and must manually specify the static IP address and the Agent’s IP and Port
  • You must provision a server but DHCP is inactive.
  • You must provision a server but DHCP is blocked by firewall rules.

CD boot images for Linux SA Provisioning in non-DHCP environments can be exported by selecting Library > By Folder > Opsware > Tools > OS Provisioning.

The images are named using the following format:

HPSA_linux_boot_cd.iso

This section provides details for provisioning in a non-DHCP environment.

When you boot an unmanaged server in a non-DHCP environment, you will see a boot screen.

After you select the boot method, you see a dialog that allows you to choose whether you want to boot your machine using DHCP or enter the static network configuration.

If you choose DHCP, SA uses your DHCP server for configuration. If you choose static, you will see a Network Configuration dialogue that allows you to enter a static IP address for the server, the subnet mask, the host gateway IP address, and the IP address and default port for the SA Agent Gateway:

You can manually configure the following fields:

  • Interface: the NIC to be used
  • IP Address: static IP address for the server being provisioned
  • Netmask: netmask for the server being provisioned
  • Default gateway: Gateway IP address the server being provisioned should use (network level IP router)
  • DNS Server: the IP address the server being provisioned should use
  • DNS Search Path: the fully qualified DNS suffix the server being provisioned should use
  • SA Server IP: IP address of the SA Core host

After the information in these fields is entered and applied, the server is able to register with the SA Core. You can now start the normal SA Provisioning process.

DHCP custom attribute

Servers that have been registered with the SA Core using a static IP specification will display the hpsa_netconfig custom attribute in the server record, as shown in the following figure:
