Create a Partition for EoIB and Associating the pkey with a VNIC and VLAN
Determine GUIDs of the Exalogic compute node the requires the VNIC as follows:
2.
a.
b.
16-10 Oracle Exalogic Elastic Cloud Machine Owner's Guide
Note:
This procedure uses 1A-ETH-3 as an example.
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
Node GUID: 0x0021280001a0a364
System image GUID: 0x0021280001a0a367
Port 1:
State: Active
Physical state: LinkUp
Rate: 40
Base lid: 120
LMC: 0
SM lid: 6
Capability mask: 0x02510868
Port GUID: 0x0021280001a0a365
Link layer: IB
Port 2:
State: Active
Physical state: LinkUp
Rate: 40
Base lid: 121
LMC: 0
SM lid: 6
Capability mask: 0x02510868
Port GUID: 0x0021280001a0a366
Link layer: IB
In the output, information about two ports is displayed. Identify the GUID
and Base lid of the port that you want to use for creating the VNIC.
For the example illustrated in this procedure, we will use the port with GUID
0x0021280001a0a366 and Base lid 121.
On the same compute node, run the following command to view information
about all the active links in the InfiniBand fabric:
hostname# iblinkinfo.pl -R | grep hostname
hostname is the name of the compute node. You can also specify the bonded
IPoIB address of the compute node.
Example:
el01cn01# iblinkinfo.pl -R | grep el01cn01
