Configuring iWARP on Linux
QLogic 41000 Series Adapters support iWARP on the Linux Open Fabric
Enterprise Distributions (OFEDs) listed in
iWARP configuration on a Linux system includes the following:
iWARP RDMA-Core Support on SLES 12 SP3, RHEL 7.4, and OFED 4.8
Installing the Driver
Install the RDMA drivers as shown in
Configuring iWARP and RoCE
To enable iWARP and RoCE:
1.
Unload all FastlinQ drivers
#
modprobe -r qedr or modprobe -r qede
2.
Use the following command syntax to change the RDMA protocol by loading
the
qed
driver with a port interface PCI ID (
xx:xx.x
) and an RDMA
protocol value (
p
).
#modprobe -v qed rdma_protocol_map=<xx:xx.x-p>
The RDMA protocol (
p
) values are as follows:
0—Accept the default (RoCE)
1—No RDMA
2—RoCE
3—iWARP
For example, issue the following command to change the interface on the
port given by 04:00.0 from RoCE to iWARP.
#
modprobe -v qed rdma_protocol_map=04:00.0-3
