Overview
|
|
========
|
|
|
|
This is the SCST development repository. It contains not a single
|
|
project SCST as one can think, but a number of them, which are divided
|
|
as the following:
|
|
|
|
1. SCST core in scst/ subdirectory
|
|
|
|
2. Administration utility for SCST core scstadmin in scstadmin/
|
|
|
|
3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc.
|
|
|
|
4. User space programs in usr/ subdirectory, like fileio_tgt.
|
|
|
|
5. Some various docs in doc/ subdirectory.
|
|
|
|
Those subprojects are in most cases independent from each other,
|
|
although some of them depend from the SCST core. They put in the single
|
|
repository only to simplify their development, they are released
|
|
independently.
|
|
|
|
Thus, use "make all" only if you really need to build everything.
|
|
Otherwise build only what you need, like for iSCSI-SCST:
|
|
|
|
make scst scst_install iscsi iscsi_install
|
|
|
|
For more information about each subproject see their README files.

QLogic target driver
|
|
====================
|
|
|
|
QLogic target driver qla2x00t is the old driver, forked from qla2xxx
|
|
several years ago. It is very stable, well tested and actively used in
|
|
many production setups. The ultimate goal is to have the mainstream
|
|
(git) QLogic target driver to be the main and the only QLogic target
|
|
driver, but, unfortunately, this driver not yet reached level of quality
|
|
and maturity of qla2x00t. We with QLogic are working toward it.
|
|
|
|
You can find the latest version of the git driver in git://git.qlogic.com/scst-qla2xxx.git.
|
|
It is maintained by QLogic, hence located in the QLogic's git.
|
|
|
|
To integrate it into the SCST build tree you need:
|
|
|
|
1. Clone the QLogic git tree somewhere in your system.
|
|
|
|
2. Create in the SCST root, i.e. this directory, a subdirectory with name
|
|
qla2x00t_git
|
|
|
|
3. Optional for the in-tree build: symlink drivers/scsi/qla2xxx
|
|
subdirectory in the cloned git tree to the qla2x00t_git subdirectory
|
|
|
|
Thats all. Now common and QLA specific root Makefile targets "magically"
|
|
start working with the new driver.
|
|
|
|
For detail instructions how to setup QLA target build environment see
|
|
its README or HOWTO. Run either "make all" to build the SCST core and
|
|
all target drivers with in-tree QLogic drivers, or the following command
|
|
with standalone QLogic drivers:
|
|
|
|
BUILD_2X_MODULE=y CONFIG_SCSI_QLA_FC=y CONFIG_SCSI_QLA2XXX_TARGET=y make all
|
|
|
|
In presence of qla2x00t_git subdirectory you can still build the
|
|
qla2x00t using qla_old* root Makefile targets.
