This section describes how to configure LNET for an InfiniBand network.
OFED InfiniBand Options
For the SilverStorm/Infinicon InfiniBand LND (iiblnd), the network and HCA may be specified, as in this example:
options lnet networks="o2ib3(ib3)"
This specifies that the node is on o2ib network number 3, using HCA ib3.
InfiniBand connectivity can be achieved using commands and options provided in
The OFED InfiniBand software suite <link to where it can be downloaded> provides commands and options to monitor and control aspects of the InfiniBand fabric. These commands are installed on and run from the Linux InfiniBand host.
To configure LNET as an InfiniBand network, see the example below.
For the SilverStorm/Infinicon InfiniBand Lustre Network Driver (iiblnd), the network and HCA can be specified by entering:
options lnet networks="o2ib3(ib3)"
In this example, the node is on o2ib network number 3 and uses HCA ib3.
