RoCE Configuration for SLES
To configure RoCE on the adapter for an SLES host, OFED must be installed and
configured on the SLES host. To install in-box OFED for SLES Linux:
1. While installing or upgrading the operating system, select the Infiniband
support packages.
2. Install the following RPMs from the corresponding SLES SDK kit image:
libibverbs-devel-x.x.x.x86_64.rpm
(required for libqedr installation)
perftest-x.x.x.x86_64.rpm
(required for bandwidth and latency applications)
3. Install the Linux drivers, as described in “Installing the Linux Drivers with
RoCE” on page 16.
Verifying the RoCE Configuration on Linux
After installing OFED, installing the Linux driver, and loading the RoCE drivers,
verify that the RoCE devices were detected on all Linux operating systems:
1. Stop firewall tables using service/systemctl commands.
2. Verify that the RDMA services has started using the
service rdma status command. If RDMA has not started, type the
following command:
# service rdma start
If RDMA does not start, type either of the following alternative commands:
# /etc/init.d/rdma start
or
# systemctl start rdma.service
3. Verify that the RoCE devices were detected by examining the dmesg logs.
# dmesg|grep qedr
[87910.988411] qedr: discovered and registered 2 RoCE funcs
4. Verify that all of the modules have been loaded. For example:
# lsmod|grep qedr
qedr 89871 0
qede 96670 1 qedr
qed 2075255 2 qede,qedr
ib_core 88311 16 qedr, rdma_cm, ib_cm,
ib_sa,iw_cm,xprtrdma,ib_mad,ib_srp,
