Identifying the Network Name of the InfiniBand HCA Port
The network name of InfiniBand HCA port is needed when creating a virtual IP over InfiniBand (IPoIB) interface. To identify the network name, do the following on the partition desktop:
Access the Windows Control Panel, click Network and Internet, click Network and Sharing Center, and then click Change adapter settings.
Under the Device Name column, locate the entries for Mellanox InfiniBand adapters. For example, Mellanox ConnectX-3 IPoIB Adapter.
Note: You may need to change the view to Details.
Under the Name column, locate the network names of the adapters and note them down. For example, Ethernet 3, Local Area Connection 3, or SLOT 3 2.
Creating a Virtual IP over InfiniBand (IPoIB) Interface
Use the Mellanox part_man utility to create a virtual IP over InfiniBand (IPoIB) interface.
Launch a Command Prompt window with administrative privileges.
Use the following command to create a virtual IPoIB with the network name of InfiniBand HCA port and the subnet tag (PKEY) of the secure fabric:
part_man [-v] add <network connection name> [iname] <pkey>Where
[-v] is a switch for verbose output.
add is the command to add a virtual interface. Only one virtual interface can be added in a single operation.
<network connection name> is a required parameter and is the network name of InfiniBand HCA port that you previously noted down. If there are spaces in the name, be sure to enclose the name within quotation marks, for example, “SLOT 3 2”.
[iname] is an optional parameter that you can specify for a printable name for the virtual interface. The printable name must start with an “i”, and not include any of the following characters: ; (semicolon), , (comma), : (colon), and - (dash). If you do not specify an iname when using the add command, the utility generates one automatically.
<pkey> is the 4 hex-digit subnet tag (PKEY) that you previously noted down.
For example,
part_man add "SLOT 3 2" ib4000 0FA0
Note: For more information on the part_man utility (usage, syntax, parameters, and so on), use the command part_man.exe -help.
Assigning an IP Address to the Virtual IP over InfiniBand (IPoIB) Interface
To assign an IP address to a virtual IP over InfiniBand (IPoIB) interface, do the following:
Access the Windows Control Panel, click Network and Internet, click Network and Sharing Center, and then click Change adapter settings.
Locate and right-click the virtual IPoIB interface, and then click Properties.
The connection properties dialog box opens.
Note: Occasionally, after a system reboot, the virtual IPoIB interface is connected but may appear to be disconnected, and the displayed status is “Network cable unplugged”. To correct the erroneous display, right-click the interface, select to disable it, and then select to enable it.
On the Networking tab, depending on the subnet type of the secure fabric that you previously noted down, click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
The internet protocol properties dialog box appears.
Select Use the following IP address, and then type an IP address within the range of available addresses of the secure fabric. Additionally, type in the subnet mask that you previously noted down.
Click OK to close the internet protocol properties dialog box.
Click OK to close the connection properties dialog.
Verifying Connection
If desired, verify that your Windows operating environment is connected to the secure fabric by issuing a ping command to another operating environment (if available) participating in the secure fabric.
