1) We are running WinIB on Windows 2003 SR2 with the OFED SRP Target.
The windows machines initially connect fine to the target, however
when they are restarted without using the "eject io unit" SCST retains

"Cannot start device".
This looks for me like an SRP target driver problem. Hopefully, Vu
(CC'ed) can answer you.
The old {srp connection, scst session} will be terminated
before the new tuple {srp connection, scst session} being
created. Please collect some traces on both win initiator
and srp target (/var/log/messages). I want to see why and
where it fail.
Using most recent WinIB, kernel 2.6.22 IB drivers, and recent SRPT and
SCST.
2) I have yet to get the WinOF 1.0 or 1.0.1 SRP Initiator to work. Is
there any reason other than my lack of trying harder that this
wouldn't work?
This is question for Vu as well
Please use the latest srp target driver in ofed-1.3
3) This may not be the forum for this, but how can you terminate a
session using SCST proc commands?
SCST can't (and shouldn't) do that, because it has no knowledge about
how sessions with particular target transport created and destroyed.
Sessions management is the target driver's duty. Ask Vu that feature.
Normally {srp connection, scst session} will be destroyed
upon disconnect reques or new connection request (without
multi-channels flag) coming from initiator or QP is in error
condition.
Sometimes we fail to terminate scst session when there are
outstanding I/Os on scst session which does not match the
outstanding I/Os on the srp connection. Right after srp
calls scst_init_cmd_done, it increases the active command
counter and decreases the counter on on_free_command.
Any idea Vlad?
