==== Infiniband Script to add IPoIB to all nodes ====

Tested on Rocks 5.1

This assumes that OFED is correctly installed. The script below will add all the compute node's ib0 interface to the database and create /etc/sysconfig/network-scripts/ifcfg-ib0.

Edit the script below to reflect the number of nodes you are editing.

<syntaxhighlight>
#!/bin/bash

rocks add network ipoib subnet=192.168.0.0 netmask=255.255.255.0;
echo "rocks add network ipoib subnet=192.168.0.0 netmask=255.255.255.0";

IP=100;
NODE=0;
NNODES=5

while [ $NODE -lt $NNODES ]; do
echo "Adding ib0 network to scarf-0-$NODE"
rocks add host interface scarf-0-$NODE ib0
rocks set host interface ip scarf-0-$NODE iface=ib0 ip=192.168.0.$IP;
rocks set host interface subnet scarf-0-$NODE iface=ib0 subnet=ipoib;
rocks set host interface name scarf-0-$NODE iface=ib0 name=ib-0-$NODE;

let IP++;
let NODE++;
done;

echo "Sync config... ";
rocks sync config;

NODE=0;

while [ $NODE -lt $NNODES ]; do
echo "Syncing network ib0 on scarf-0-$NODE...";
rocks sync host network scarf-0-$NODE;

let NODE++;
done
