Greetings all,
It is my great honor to announce the Target_Core_Mod/ConfigFS infrastructure project
has reached v3.4.0-rc1 and is again tracking linux-2.6.git HEAD at v2.6.34-rc1. The
kernel code can be found here:
http://git.kernel.org/?p=linux/kernel/git/nab/lio-core-2.6.git;a=summary
With this release marks the merge of the Open-FCoE.org based target module (tcm_fc) for
TCM/ConfigFS 3.x contributed by Joe Eykholt as the third fabric module available in
lio-core-2.6.git/master. This has included in a seperate release announcement, and
information for the TCM Open-FCoE.org target module can be found here:
http://www.linux-iscsi.org/index.php/Openfcoe
This release also reaches the milestone of TCM/ConfigFS becoming the first and only Linux
target mode project to run in multi-fabric mode across all known feature bits for SPC-4
defined persistent reservations (PR) using iSCSI, FCoE and Virtual SAS ports. This patch series
and test case to make that happen for PR features SPEC_I_PT=1 and REGISTER_AND_MOVE was originally
posted here:
http://permalink.gmane.org/gmane.linux.scsi/57831
For more information about TCM/ConfigFS and fabric module usage with PR+ALUA, please have a look at:
http://www.linux-iscsi.org/index.php/Target_Core_Mod/ConfigFS
http://www.linux-iscsi.org/index.php/Persistent_Reservations
http://www.linux-iscsi.org/index.php/ALUA
Finally as no announcement would be complete without an multi-fabric demonstration, here is how
explict/implict ALUA multipath using upstream scsi_dh_alua is looking with Open-iSCSI + Open-FCoE
Initiators between TCM LIO-Target iSCSI and Open-FCoE.org target ports. This is done by seperate
the iSCSi and FCoE Target ports into two different ALUA Target Port Groups (1gb_iscsi and 1gb_fcoe
respectively) for the same TCM/FILEIO LUN backstore.
Any constructive comments or questions are welcome!
