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.
