Chapter 1. Introduction

Software Requirements

cxgb4, toecore, t4_tom, chiscsi_base and scst modules are required by chiscsi_t4.ko module to
work in offloaded mode supporting SCST. Whereas in iSCSI non-offloaded target (NIC) mode,
only cxgb4 and scst are needed by chiscsi_base.ko module.
1.3.1. Linux Requirements
Currently the iSCSI Target driver is available for the following versions:
Ubuntu 14.04.1, 3.13.0-32-generic
Ubuntu 14.04.1, 3.13.X recompiled with scst_exec_req_fifo-<kernel-version> patch*
* Download the 3.13.X kernel using apt-get source linux-image-$(uname -r).
Kernel.org 3.13.X is not supported.
Other kernel versions have not been tested and are not guaranteed to work.
1.3.2. Requirements for Installing the iSCSI Software
When installing the iSCSI software, it is required that the system have Linux kernel source or its
headers installed in order to compile the iSCSI software as a kernel module. The source tree
may be only header files, as for RHEL6 as an example, or a complete tree. The source tree
needs to be configured and the header files need to be compiled. Additionally, the Linux kernel
must be configured to use modules.
