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.
NOTE: The nwmgr utility is a unified command, introduced in HP-UX 11i v3, intended to
replace the existing lanadmin, lanscan, and linkloop commands, which are being deprecated,
but are still available on HP-UX 11i v3. See nwmgr(1M) for details.
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
Listing All IPoIB Interfaces (HP-UX 11i v3 only) To list all IPoIB interfaces.
Syntax and Example: nwmgr -S ipoib
Listing All IPoIB Interfaces (HP-UX 11i v2 and 11i v3 ) To list all IPoIB interfaces.
Syntax and Example: lanadmin -x [if_info] | link_info | all_if_info ]
<ipoib_ppa>
Display Details of an IPoIB Interface (HP-UX 11i v3 only) To display details of a particular
interface.
Syntax and Example: nwmgr[-v] -c lan9000
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 “IPoIB Administration and Management” (page 67) for
additional information on the IPoIB interface.
