HP Integrity iLO 2 MP 5991-6005 manual Configuring the iLO 2 MP LAN Using Dhcp and DNS

Configuring the iLO 2 MP LAN Using DHCP and DNS

DHCP automatically configures all DHCP-enabled servers with IP addresses, subnet masks, and gateway addresses. All HP Integrity entry class servers with the iLO 2 MP are shipped from the factory with DHCP enabled.

HP recommends using the DHCP and DNS method to simplify access to the iLO 2 MP.

NOTE: You can use ARP Ping regardless of the status of DHCP unless an IP address has ever been acquired using DHCP. Once an IP address is assigned using DHCP, ARP Ping is permanently disabled.

When you use DHCP and DNS, you can connect to the iLO 2 MP by entering the DNS name in your browser rather than an IP address only if the following applies:

•DHCP must be enabled (DHCP is enabled by default).

•You are using a DHCP server that provides the domain name.

•The primary DNS server accepts dynamic DNS (DDNS) updates.

•The primary DNS server IP address was configured through the DHCP server.

IMPORTANT: You must know the DNS domain name, which is served out by the DHCP server, unless its domain is local or the same domain.

To configure the iLO 2 MP using DHCP and DNS, follow these steps:

1.Obtain the factory-set DNS name from the toe-tag on the server. The DNS name is 14 characters long. It consists of the letters MP followed by the 12 characters of the MAC address. For example:

mp0014c29c064f

This address is assigned to the iLO 2 MP system board. The system board has a unique MAC address that identifies the hardware on the network.

2.Connect the iLO 2 MP LAN cable from the server to an active network port.

3.Apply ac power to the server.

4.Open a browser, telnet, or SSH client and enter the DNS name. The iLO 2 MP Log In window appears.

5.Log in using the default user name and password (Admin/Admin).

CAUTION: When DHCP is enabled, the system is vulnerable to security risks because anyone can access the iLO 2 MP until you change the default user name and password.

HP strongly recommends you assign user groups and rights before proceeding.

Configuring the iLO 2 MP LAN Using ARP Ping

NOTE: You can use ARP Ping regardless of the status of DHCP unless an IP address has ever been acquired using DHCP. Once an IP address is assigned using DHCP, ARP Ping is permanently disabled. Some DHCP server options can cause the apparent issuance of ARP Ping to the iLO 2 MP, which negates the DHCP over DNS method.

The Address Resolution Protocol (ARP) and Packet Internet Grouper (Ping) utility uses ARP packets to ping (discover) a device on the local network segment. The IP address you assign to the server must use the same network segment (subnet) as the system assigning the address. ARP does not work across routed or switched networks.

Use the ARP Ping utility to assign a static IP address when you do not have access to the console serial port (RS-232) or when DHCP is not available.
