AH304A HP Fabric Clustering System PCIe 2-port 4X DDR Fabric Adapter Installation Guide

12. Verify that all installed fabric adapters have a software state of CLAIMED, by running the
ioscan -fk -C ib command.
Internet Protocol over InfiniBand (IPoIB)
In order to use the Internet Protocol over InfiniBand™ (IPoIB) the same patches need to be
installed on each server used for IPoIB in the HP Fabric Clustering System. For current patch
requirement , see the latest HP Fabric Clustering System for InfiniBand Support Matrix on
http://www.docs.hp.com .
The ifconfig command provides information about the IPoIB interface, enables or disables an
IPoIB interface, configuring the link to the HP Fabric Clustering System.
Checking the IPoIB Interface Status To check the current status of the IPoIB interface.
Syntax and example: ifconfig lan9000
Output Example:
lan9000: flags=842<BROADCAST,RUNNING,MULTICAST>
inet 192.32.32.255 netmask ffffff00 broadcast 192.32.32.255
Enable the IPoIB Interface To enable the IPoIB interface.
Syntax: ifconfig <ipoib_interface> [address] [netmask] up
Example: ifconfig lan9000 192.32.32.255 up
There is no direct output from this command.
To confirm that the interface is UP, run the ifconfig lan9000 command again.
Output Example:
lan9000: flags=843<UP,BROADCAST,RUNNING,MULTICAST>
inet 192.32.32.255 netmask ffffff00 broadcast 192.32.32.255
Managing the IPoIB Interface See the HP Fabric Clustering System - HP-UX Administrator's Guide
for additional information on the IPoIB interface.
On-Line Addition and Replacement Operations (OL*)
On-Line Addition and Replacement (OL*) of HP Fabric adapters is supported on HP Fabric
Clustering System version B.11.23.02 or newer with a couple of limitations related to replacing
an HCA, see below.
Replacing an HP Fabric Clustering System HCA
Use the Attention Button method of On-Line Addition and Replacement (OL*) to replace an
existing HP Fabric Clustering System HCA. You can also use the Command Line Interface, or
Peripheral Device Tool graphical user interface (GUI), to replace an HP Fabric HCA. Refer to the
Interface Card OL* Support Guide, available on http://www.docs.hp.com for details on using standard
OL* features.
HP Fabric HCAs can also be added using the Attention Button feature.
