10.2 Set Up Ethernet Over InfiniBand (EoIB) on Oracle Linux
To set up Ethernet over InfiniBand connectivity for an Exalogic compute node running
Oracle Linux, complete the following steps:
1. Use an SSH client, such as PuTTY, to log in to a Sun Network QDR InfiniBand
Gateway Switch. Oracle recommends that you log in as the root user. For
example, log in to el01gw04 as root.
2. At the command prompt, run the following command:
el01gw04# listlinkup | grep Bridge
The following is an example of the output of the listlinkup command:
Connector 0A-ETH Present
Bridge-0 Port 0A-ETH-1 (Bridge-0-2) up (Enabled)
Bridge-0 Port 0A-ETH-2 (Bridge-0-2) up (Enabled)
Bridge-0 Port 0A-ETH-3 (Bridge-0-1) up (Enabled)
Bridge-0 Port 0A-ETH-4 (Bridge-0-1) up (Enabled)
Bridge-0 Port 1A-ETH-1 (Bridge-1-2) down (Enabled)
Bridge-0 Port 1A-ETH-2 (Bridge-1-2) down (Enabled)
Bridge-0 Port 1A-ETH-3 (Bridge-1-1) up (Enabled)
Bridge-0 Port 1A-ETH-4 (Bridge-1-1) up (Enabled)
From this output, identify the uplinks. You can determine that you can use any of
the following Ethernet connectors for creating a VNIC:
• 0A-ETH-1
• 0A-ETH-2
• 0A-ETH-3
• 0A-ETH-4
• 1A-ETH-3
• 1A-ETH-4
Note:
This procedure uses 1A-ETH-3 as an example.
3. Determine GUIDs of the Exalogic compute node that requires the VNIC, as
follows:
a.
On the compute node that requires the VNIC, log in as root, and run the
ibstat command on the command line. For example, log in to el01cn01 as
root.
Example:
el01cn01# ibstat
CA 'mlx4_0'
CA type: MT26428
Number of ports: 2
Firmware version: 2.7.8100
Hardware version: b0
