Do you have any reservations that the WinIB (Mellanox) SRP initiators
will not work with SRPT?
There are two version of SRPT: ofed/gen2 srpt and ibgold srpt
You are working with ofed/gen2 srpt now
WinIB srp initiator works well with ibgold srpt
I quickly test WinIB srp intiator with ofed/gen2 srpt. It sees the
target but not its lun - some debugs are required
ibgold srpt only work with suse/sles 9, rhel 4. It does not work with
rhel 5 or sles10 or vanilla kernel > 2.6.11
Do you have any restriction on kernel, version of IB driver/srpt driver
on the target machine?
If there is any doubt, I need to know so that I can fall back to iSCSI
over IPoIB (iSIPIB??? ;) ) . This has lots more overhead, but it's a
sure bet until this can be worked out.

Thanks for doing this.
Please use the latest readme from this link -

WinIB initiators --> Gentoo Linux SRP Target.
I mainly test linux initiators with gen2 srp-target. I have
not tested win srp initiator with the target.
Anything wrong with the above approach, I would be interested in a best
practices if there is one. I saw a CentOS target post, is this more
stable or better performing?
There is no difference when you run the same srp target /
scst codes in CentOS or RH/SuSe linux distributions. The
storage back-end will determine the performance

Thanks.

Compiling on kernel 2.6.21-rc6 from kernel.org Torvald's branch
Got the latest srpt from the git repository on OpenFabrics and had the
following issues.
ib_srpt.c Line 1997, missing second argument, should be?
sdev->scst_tgt = scst_register(tp, NULL);
Yes. You need the change if you test with top of scst svn
trunk (or from version 0.9.6-pre2)
If you test with scst before 0.9.6-pre2 (ie. version <=
0.9.6-pre1) you don't need the second argument for
scst_register()
SCST was built successfully after fixing an issue in scst_vdisk.c
(missing #include <linux/sched.h>)
I tested with 2.6.20.x - I have not tested with 2.6.21-rcXX
- you should send the patch to scst devel
Just thought this would be nice to have documented, took me half a day
to track down as a novice in C programming.
there is *lean and mean* srpt's README in srpt_inc
SCST also has some document
You can add some wiki/notes for the problems in openfabrics
wiki page https://wiki.openfabrics.org/tiki-index.php
