2 – InfiniPath Cluster Administration Configuration and Startup

Q

To verify the configuration, type:

#ifconfig ib0

The output from this command should be similar to this:

ib0 Link encap:InfiniBand HWaddr 00:00:00:02:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00 inet addr:10.1.17.3 Bcast:10.1.17.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:2044 Metric:1

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

Next, type:

#ping -c 2 -b 10.1.17.255

The output of the ping command should be similar to that below, with a line for each host already configured and connected:

WARNING: pinging broadcast address

PING 10.1.17.255 (10.1.17.255) 517(84) bytes of data.

174 bytes from 10.1.17.3: icmp_seq=0 ttl=174 time=0.022 ms

64bytes from 10.1.17.1: icmp_seq=0 ttl=64 time=0.070 ms (DUP!)

64bytes from 10.1.17.7: icmp_seq=0 ttl=64 time=0.073 ms (DUP!)

The IPoIB network interface is now configured.

NOTE: The configuration must be repeated each time the system is rebooted.

OpenSM

OpenSM is an optional component of the OpenFabrics project that provides a subnet manager for InfiniBand networks. This package can be installed on all machines, but only needs to be enabled on the machine in your cluster that is going to act as a subnet manager. You do not need to use OpenSM if any of your InfiniBand switches provide a subnet manager.

After installing the opensm package, OpenSM is configured to be on on the next machine reboot. It only needs to be enabled on the node which acts as the subnet manager, so use the chkconfig command (as root) to disable it on the other nodes:

#chkconfig opensmd off

The command to enable it on reboot is:

#chkconfig opensmd on

You can start opensmd without rebooting your machine as follows:

# /etc/init.d/opensmd start
