Configuring iSER for RHEL
To configure iSER for RHEL:
1. Install inbox OFED as described in “RoCE Configuration for RHEL” on
page 150.
2. Unload any existing FastLinQ drivers as described in “Removing the Linux
Drivers” on page 10.
3. Install the latest FastLinQ driver and libqedr packages as described in
“Installing the Linux Drivers with RDMA” on page 14.
4. Load the RDMA services as follows:
systemctl start rdma
modprobe qedr
modprobe ib_iser
modprobe ib_isert
5. Verify that all RDMA and iSER modules are loaded on the initiator and target
devices by issuing the
lsmod | grep qed and lsmod | grep iser
commands.
6. Verify that there are separate
hca_id instances by issuing the
ibv_devinfo
command, as shown in Step 6 on page 153.
7. Check the RDMA connection on the initiator device and the target device.
a. On the initiator device, issue the following command:
rping -s -C 10 -v
b. On the target device, issue the following command:
rping -c -a 192.168.100.99 -C 10 -v
NOTE
Out-of-box OFEDs are not supported for iSER because the ib_isert
module is not available in the out-of-box OFED 3.18-2 GA/3.18-3 GA
versions. The inbox ib_isert module does not work with any out-of-box
OFED versions.
