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 inbox 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
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.
To verify RoCE configuration on Linux:
1.
Stop firewall tables using
service/systemctl
commands.
2.
For RHEL only, verify if the RDMA service has started.
Use the
service rdma status
command to start service:
If RDMA has not started, issue 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
NOTE
For RHEL 6.x and SLES 11 SP4, you must start RDMA service after
reboot. For RHEL 7.
x
and SLES 12 SPX and later, RDMA service
starts itself after reboot.
