Chapter X. iSCSI PDU Offload Target

Chelsio Unified Wire for Linux

157

configurable item is

“ACL” (for Access Control List). “ACL” is one of the few items that have no

default.

Before starting any iSCSI target, an iSCSI configuration file must be created. An easy way to
create this file is to use the provided sample configuration file and modify it. This file can be named
anything and placed in any directory but it must be explicitly specified when using iscsictl by using
the -f option. To avoid this, put configuration file in the default directory

(/etc/chelsio-iscsi

)

and name it the default file name (

chiscsi.conf

).

“On the fly” Configuration Changes

Parameters for the most part can be changed while an iSCSI node is running. However, there are
exceptions and restrictions to this rule that are explained in a later section that describes the
details of the iSCSI control tool

iscsictl

.

4.3.

A Quick Start Guide for Target

This section describes how to get started quickly with a Chelsio iSCSI target. It includes:

Basic editing of the iSCSI configuration file.
Basic commands of the iSCSI control tool including how to start and stop a target.

A Sample iSCSI Configuration File

The default Chelsio iSCSI configuration file is located at

/etc/chelsio-iscsi/chiscsi.conf

.

If this file doesn’t already exist, then one needs to be created.

To configure an iSCSI target, there are three required parameters (in the form of key=value pairs)
needed as follows:

TargetName

– A worldwide unique iSCSI target name.

PortalGroup

– The portal group tag associating with a list of target IP address (es) and port

number(s) that service the login request. The format of this field is a Chelsio specific iSCSI
driver parameter which is described in detail in the configuration file section.

TargetDevice

– A device served up by the associated target. A device can be:

•

A block device (e.g., /dev/sda)

•

A virtual block device (e.g., /dev/md0)

•

A RAM disk

•

A regular file

A target can serve multiple devices, each device will be assigned a Logical Unit Number (LUN)
as per the order it is specified (i.e., the first device specified is assigned LUN 0, the second one
LUN 1, …, and so on and so forth). Multiple TargetDevice key=value pairs are needed to indicate
multiple devices.
