Chapter VIII. iSCSI PDU Offload Initiator
Chelsio T5/T4 Unified Wire For Linux Page 140
2. Software/Driver Loading
The driver must be loaded by the root user. Any attempt to load the driver as a regular user will
fail.
Run the following command to load the driver:
[root@host]# modprobe cxgb4i
On SLES, load the driver with --allow option:
[root@host]# modprobe cxgb4i --allow
If installing the Chelsio Unified Wire package doesn’t install the cxgb4i driver properly on SLES,
then follow these steps to configure your source tree and then re-install the package:
[root@host]# cd /usr/src/linux
[root@host]# make clean
[root@host]# make oldconfig
[root@host]# make scripts
If loading the driver fails, then follow the steps mentioned below and try again.
i. Run the following command to view all the loaded iSCSI modules
[root@host]# lsmod | grep iscsi
 Sometimes open-iSCSI fails to compile because of dependencies on
libopenssl-devel (for SLES11SP1) or openssl-devel(for RHEL 6) packages,
so install these packages first and then install the Chelsio Unified Wire
package (such issue is not seen while installing package using RPM).
 If loading of cxgb4i displays "unkown symbols found" error in dmesg, then kill
iscsid, unload all open iSCSI modules and related/dependent modules (like
multipath, bnx2i etc) and then reload cxgb4i driver.
