Info

6.2.1 BOOTP DHCP is an extension to the original BOOTP specification. As a result, you can use the DHCP daemon (dhcpd) to provide the BOOTP information for booting via the network. The DHCP daemon is configured through the /etc/dhcpd.conf file. Example 6-7 shows the configuration that we used in our lab. With dhcpd configured, start the DHCP daemon as shown here: # /etc/init.d/dhcpd start Example 6-7 /etc/dhcpd.conf always-reply-rfc1048 true; allow bootp; deny unknown-clients; not authoritative; default-lease-time 600; max-lease-time 7200; subnet 192.168.1.0 netmask 255.255.255.0 { group { next-server 192.168.1.1; } Attention: Keep in mind that Example 6-7 contains IP and MAC address information specific to our lab environment. See your product documentation or the dhcpd man page to customize this for your site. } 110 The IBM Eserver BladeCenter JS20 host blade1 { fixed-address 192.168.1.117; hardware ethernet 00:0d:60:1e:0f:89; filename "zImage.initrd.suse"; } host blade2 { fixed-address 192.168.1.118; hardware ethernet 00:0d:60:1e:0e:fb; filename "zImage.initrd.redhat"; }
6.2.2 Trivial File Transfer Protocol The TFTP daemon for both distributions considers the /tftpboot directory its home. Any file name statements made in the /etc/dhcpd.conf configuration file should be relative to this path. Both RHEL and SLES spawn TFTP from the xinetd daemon. By default, tftpboot is disabled on both distributions. To enable both xinetd and TFTP, enter: [root@blade1 root]# chkconfig tftp on [root@blade1 root]# /etc/init.d/xinetd restart Your installation server is now ready to network boot the BladeCenter JS20. 6.3 Preparing an unattended install RHEL and SLES both have their own methods of conducting an unattended installation. RHEL uses Kickstart, and SLES uses a method known as AutoYaST. Chapter 6. Installing Linux 111
