How to set the static IP address for compute nodes?

Question & Answer


Question

This article described the static ip address setting for compute nodes in the cluster.

Answer

Spectrum cluster foundation use DHCP to assign ip address to computer nodes in the cluster.

Accurately, fixed ip addresses were assigned to computer nodes. You can check /var/lib/dhcpd/dhcpd.leases for this setting. Below is the example and we can see the fixed ip 10.100.100.3 was assigned to compute000.

========================


host compute000 {
dynamic;
hardware ethernet 00:0c:29:6e:8b:04;
fixed-address 10.100.100.3;
supersede server.ddns-hostname = "compute000";
supersede host-name = "compute000";
if option user-class-identifier = "xNBA" and option client-architecture
= 00:00 {
supersede server.filename =
"http://${next-server}/tftpboot/xcat/xnba/nodes/compute000";
} elsif option client-architecture = 00:00 {
supersede server.filename = "xcat/xnba.kpxe";
} else {
supersede server.filename = "";
}
