148
BC0154501-00 P
On RHEL or CentOS: 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, issue 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,
ib_ucm,ib_iser,ib_srpt,ib_umad,
ib_uverbs,rdma_ucm,ib_ipoib,ib_isert
5.
Configure the IP address and enable the port using a configuration method
such as ifconfig. For example:
#
ifconfig ethX 192.168.10.10/24 up
6.
Issue the
ibv_devinfo
command. For each PCI function, you should see a
separate
hca_id
, as shown in the following example:
root@captain:~#
ibv_devinfo
hca_id: qedr0
transport: InfiniBand (0)
fw_ver: 8.3.9.0
node_guid: 020e:1eff:fe50:c7c0
sys_image_guid: 020e:1eff:fe50:c7c0
vendor_id: 0x1077
vendor_part_id: 5684
hw_ver: 0x0
phys_port_cnt: 1
