TargetCLI is the LIO commmand-line administration tool for managing the Linux SCSI Target, and its third-party target fabric modules and backend storage objects.
Based on RTSLib, it allows direct manipulation of all SCSI Target objects like storage objects, SCSI targets, TPGs, LUNs and ACLs, as well as manage startup system configuration for the SCSI Target subsystem.
TargetCLI can be used either as a regular CLI tool, one command at a time, or as an interactive shell based on the python configshell CLI framework, with full auto-complete support and inline documentation.
TargetCLI is part of the Linux Kernel's SCSI Target's userspace management tools.
TargetCLI is currently part of several Linux distributions. In most cases, simply installing the version packaged by your favorite Linux distribution is the best way to get it running.
Migrating away from a targetcli < 3.0 setup
Prior to version 3.x, TargetCLI relied on lio-utils for managing the target's
startup configuration. Unfortunately, rtslib.Config - now used by targetcli and
/etc/init.d/target initscript for startup config save and restore
operations - is incompatible with the legacy lio-utils config files.
However, the new initscript has a special provision for this case.
When attempting to start the target service when there is no
/etc/target/scsi_target.lio configuration file present, a check is made to see
if there is a target configuration currently running on the system. If there is,
it is assumed to be a keeper, and the initscript will attempt to dump it to the
system startup configuration file
When migrating from a lio-utils install, the trick is to prevent the old lio-utils
package removal from stopping the service. For this, you can simply empty the
lio-utils version of
/etc/init.d/target - or the equivalent location for your
Example on Debian:
echo > /etc/init.d/target dpkg --purge lio-utils apt-get install targetcli
Building from source
The packages are very easy to build and install from source as long as you're familiar with your Linux Distribution's package manager:
Clone the github repository for TargetCLI using
git clone https://github.com/Datera/targetcli.git.
Make sure build dependencies are installed. To build TargetCLI, you will need:
- GNU Make.
- python 2.6 or 2.7
- A few python libraries: rtslib, configshell, lio-utils
- Your favorite distribution's package developement tools, like rpm for Redhat-based systems or dpkg-dev and debhelper for Debian systems.
From the cloned git repository, run
make debto generate a Debian package, or
make rpmfor a Redhat package.
The newly built packages will be generated in the
