Installing HP Fabric Clustering System
Internet Protocol over InfiniBand‘ (IPoIB)
Chapter 4
38
There are important differences in technology between IPoIB and Ethernet. These should be considered to
decide the best use of IPoIB within your HP Fabric Clustering System:
Setting promiscuous mode over IPoIB interfaces is not supported
Setting link layer parameters link link address, MTU etc. on IPoIB interfaces is not suported
DLPI RAW mode applications or DLPI connection oriented applications are not supported
Installation Pre-requisites
For a fully functional IPoIB implementation, the following additional software must be installed:
TOUR product bundle (A.02.00 Transport Optional Upgrade Release for B.11.23)
DLPI patch PHNE_30242
NetTL patch PHNE_30451
SAM patch PHCO_29666 (optional)
IP Filter product version A.03.05.09 or A.03.05.06.V2. The latest version of the IP Filter product is
available on the web site http://www.software.hp.com.
TOUR is a transport software bundle that provides TCP/IP transport stack hooks to a variety of transport
protocols, including IPoIB over an HP Fabric Clustering System network. The DLPI patch is required for the
IPoIB driver to register IPoIB interfaces. Both the TOUR bundle and the DLPI patch allow for configuration
of IPv4 and IPv6 addresses using the ifconfig utility. Additionally, the TOUR bundle and DLPI patch
contain other tools used for administration and management of IPoIB. As an option, SAM will perform the
same function as the ifconfig utility, but through a GUI.
Once the TOUR bundle, DLPI patch and the IPoIB driver are installed, the node will automatically create
IPoIB links to the HP Fabric Clustering System. One IPoIB interface is created for every port installed on the
system.
Enabling the IPoIB Interface
ifconfig Command
Description: This command enables or disables an IPoIB interface, configuring the link to the HP Fabric
Clustering System.
Syntax: ifconfig lan9000
Example: # lan9000
Output Example:
lan9000: flags=843<UP,BROADCAST,RUNNING,MULTICAST>
inet 100.99.99.53 netmask fffff800 broadcast 100.99.103.255
hptem052 1010: ifconfig lan9000 inet6
lan9000: flags=4800841<UP,RUNNING,MULTICAST,PRIVATE,ONLINK>
inet6 fe80::202:c902:0:77d prefix 10
