HP XC System Software Installation Guide Version 2.1

Follow this procedure to configure network access to the Myrinet switch monitoring line cards:
1. Begin this procedure as the root user on the head node.
2. Ensure that an Ethernet cable from the monitoring line card primary Ethernet port is
connected to an Ethernet port on the admin root switch. This connection is d escribed in
the HP XC System Softwa re H ardware Preparation Guide.
3. Obtain the line card MAC address from the label on the front panel of the Myrinet switch.
4. Use the text editor of your choice to op en the /etc/dhcpd.conf file, and add the
following lines inside the c o nfigu ration block that begins with: shared-network
XC {. Enter the MAC address obtained in step 3 , and use the number zero (0), not the
letter O, in the host name MR0N00.
host MR0N00 {
hardware ethernet your_MAC_address;
option host-name "MR0N00";
fixed-address 172.20.66.1;
}
In the following exam ple, the entry is added to the end of the shared-network XC
{ block:
#Built by Blddhcpd in DiscoverTools.pm
ddns-update-style none;
deny unknown-clients;
allow bootp;
default-lease-time 480;
max-lease-time 480;
option xc-macaddress code 232 = string;
shared-network XC {
subnet 172.0.0.0 netmask 255.224.0.0 {
next-server 172.20.0.8;
filename = "/pxelinux.0";
host cp-n1 {
hardware ethernet 00:11:85:5c:1b:dc;
option host-name "cp-n1";
fixed-address 172.21.0.1;
# location "Level 2 Switch 172.20.65.4, Port 1";
}
.
.
.
host n3 {
hardware ethernet 00:11:0a:ea:ea:41;
option host-name "n3";
fixed-address 172.20.0.3;
option xc-macaddress "00:11:0a:ea:ea:41";
# location "Level 2 Switch 172.20.65.3, Port 3";
}
host MR0N00 {
hardware ethernet your_MAC_address;
option host-name "MR0N00";
fixed-address 172.20.66.1;
}
}
}
5. Restart the DHCP service:
# service dhcpd restart
6. Use the text editor of your choice to o pen t he /etc/hosts file to in clude an entry for
each monitoring line card, using the data in Table G-2 as a reference:
172.20.66.1 MR0N00
