Configuring iSER for RHEL
To configure iSER for RHEL:
1. Configure in-box OFED, as described “RoCE Configuration for RHEL” on
page 64. Out-of-box OFEDs are not supported for iSER because the ib_isert
module is not available in the out-of-box OFED-3.18/3.81-1 GA versions.
The inbox ib_isert module does not work with any out-of-box OFED
versions.
2. Unload any existing FastLinQ drivers, as described in “Removing Linux
Drivers in a RoCE Environment” on page 13.
3. Install the latest FastLinQ driver and libqedr packages, as described in
“Installing the Linux Drivers with RoCE” on page 16.
4. Load the RDMA services.
systemctl start rdma
modprobe qedr
modprobe ib_iser
modprobe ib_isert
5. Verify all RDMA and iSER modules loaded on the initiator and target devices
using the lsmod | grep qed and lsmod | grep iser commands.
6. Verify that there are separate hca_id instances by typing the ibv_devinfo
command, as described in Step 6 on page 66.
7. Check the RDMA connection on the initiator device and the target device.
Initiator device:
rping -s -C 10 -v
Target device:
rping -c -a 192.168.100.99 -C 10 -v
