Determining the iLO 2 MP LAN Configuration Method

To access the iLO 2 MP through the iLO 2 MP LAN, the iLO 2 MP must acquire an IP address. The way the iLO 2 MP acquires an IP address is dependent upon whether DHCP is enabled or disabled on the server, and if DHCP and DNS services are available to the server. (See Table 3-12for possible scenarios.)

Once you have determined the iLO 2 MP access, you must determine how you will configure the iLO 2 MP LAN in order to acquire an IP address. There are three methods available.

•DHCP/DNS

•ARP Ping

•RS-232 serial port

Table 3-12provides all the possible scenarios to consider. Use this table to help you select the appropriate LAN configuration method to obtain an IP address.

Once you have determined how you will configure the iLO 2 MP LAN in order to acquire an IP address, you must configure the iLO 2 MP LAN using the selected method.

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 typing the default host name in your browser rather than an IP address only if the following applies:
