So Microsoft isns server considers the last request as the storage node and doesn't discover the previous targets. Root Cause ---------------- Function ISNS_FUNC_DEV_ATTR_REG Target A Source attribute ISCSI-Name = <IQN A Name> Operating Attribute ISCSI-Name = <IQN A Name> Flags Replace Access = 1 Target B Source attribute ISCSI-Name = <IQN B Name> Operating Attribute ISCSI-Name = <IQN B Name> Replace Access = 1 So as per the request format Microsoft isns Server always takes the last target as the source node. and register the same. Hence it doesn't discover the targets other than last one. The Source Attribute has to be fixed for all targets. It would be better if we use the first target iscsi name (rather than the last target iscsi name) as source attribute iscsi name to represent the storage node. ........ r3866 | bvassche | 2011-09-18 03:38:37 -0400 (Sun, 18 Sep 2011) | 1 line ib_srpt: Reduce the Last WQE wait time ........ r3867 | bvassche | 2011-09-18 04:01:29 -0400 (Sun, 18 Sep 2011) | 1 line Follow-up for r3866 ........ r3869 | bvassche | 2011-09-18 07:04:10 -0400 (Sun, 18 Sep 2011) | 1 line ib_srpt: Show the state name in debug messages ........ r3870 | bvassche | 2011-09-18 07:15:17 -0400 (Sun, 18 Sep 2011) | 6 lines ib_srpt: Fix "rejected SRP_LOGIN_REQ because creating a new RDMA channel failed" Fix two race conditions that could trigger this failure: - Completion thread not woken up after channel state change. - Reception of Last WQE event before the channel queue pair was reset. ........ r3872 | bvassche | 2011-09-18 08:23:13 -0400 (Sun, 18 Sep 2011) | 1 line ib_srpt: Remove a superfluous __srpt_close_ch() call ........ r3875 | bvassche | 2011-09-22 13:49:04 -0400 (Thu, 22 Sep 2011) | 1 line ib_srpt: Clean up two PRINT_ERROR() statements ........ r3876 | bvassche | 2011-09-22 13:49:45 -0400 (Thu, 22 Sep 2011) | 1 line ib_srpt: Remove an outdated comment ........ r3877 | bvassche | 2011-09-22 13:51:19 -0400 (Thu, 22 Sep 2011) | 1 line ib_srpt: Avoid that the cleanup code invoked after rejecting a new initiator connection triggers a race condition ........ r3879 | bvassche | 2011-09-24 10:11:39 -0400 (Sat, 24 Sep 2011) | 1 line scst, latency statistics: Introduce timespec_to_ns(). ........ r3882 | vlnb | 2011-09-27 22:07:50 -0400 (Tue, 27 Sep 2011) | 3 lines Change reporting processed_cmds to unsigned as suggested by ido benda <idombd@gmail.com> ........ r3883 | vlnb | 2011-09-27 22:18:44 -0400 (Tue, 27 Sep 2011) | 5 lines Micro-optimize scst_unpack_lun(): avoid comparing "len" twice with the constant "2".

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.
