Latest istgt has three modes. 1) default or QueueDepth=0 This mode uses single thread per connection. 2) QueueDepth=32 or any choice except zero (20100707 compatible) This mode uses one thread per connection and one thread per LUN. 3) QueueDepth with -m1 command line option (experimental) This mode uses two threads per connection and one thread per LUN. The experimental mode is intended to be used by Hexa core CPU and 10Gbps link, and to be improved for 4KB random concurrent I/O. Single core CPU is not supported under this mode.

Im trying to solve some problems we have with a FreeBSD 7.3 and a Dell MD3000i. The main problem seem to be that FreeBSD does not have support for multipath? We get nasty crashes sometimes and it seems to be during a switchover/failover event on the storage. I have seen some discussions about this with Danny and his great work bringing iSCSI initiator to FreeBSD. But i have not really been able to find that the iSCSI driver now supports it or if it is coming soon? Or if there are any other ways to avoid system crashes when the storage is switching between it's storage controllers? I also found some later versions at Danny's ftp, ftp://ftp.cs.huji.ac.il/users/danny/freebsd/ But im not sure it will be any more features or if it will work with a 7.3 src? ( ftp://ftp.cs.huji.ac.il/users/danny/freebsd/iscsi-2.3.1.tar.gz ) I hope you guys on the list can help.

However, I get these hangs every once in a while to the tune of: mfi0: COMMAND xxxxx Timeout After 60 seconds And that repeats every 30 seconds. I can 'fix' it by doing a: mfiutil show volumes Oddly enough. It then 'unfreezes'. BTW, I'm on 8.2-PRERELEASE, with the latest snapshot from March 1st, 2011. Now, I was following this thread: http://old.nabble.com/mps%284%29-driver-%28LSI-6Gb-SAS%29-commited-to-stable= -8-td30960262.html And it looks like I may be able to use the MPT driver instead of MFI to reso= lve my problem?

Hmm.. it seem that the MPS driver is in the source on 8-PRERELEASE from March 1st 2011, so I think I have it from when I compiled the most recent kernel: # find /usr/src -type f -name \*mps\* /usr/src/sys/dev/mps/mps.c /usr/src/sys/dev/mps/mps_ioctl.h /usr/src/sys/dev/mps/mps_pci.c /usr/src/sys/dev/mps/mps_sas.c /usr/src/sys/dev/mps/mps_table.c /usr/src/sys/dev/mps/mps_table.h /usr/src/sys/dev/mps/mps_user.c /usr/src/sys/dev/mps/mpsvar.h Is there any way I can load MPS instead of MFI to manage my Perc H800 LSI controller? Maybe an rc.conf line to add or something? I looked around for MPS documentation but couldn't find any as of yet. TIA!

Maybe an rc.conf line to add or something? I looked > around for MPS documentation but couldn't find any as of yet. Just for fun I tried building a custom kernel without MFI support, in an attempt to force the MPS driver to recognize my devices, but was foiled because my boot device (Perc 6i) needed MFI to work, so it wouldn't boot. So I reverted to my old kernel. I guess it would be most useful if I could somehow force MFI to be used on my boot disk as it is now, but use MPS on my 24 JBOD disks coming from the Perc H800 SAS controller...? They are JBOD because I have them roped into a ZFS filesystem.

I just checked and the Perc H800 uses the LSI SAS2108 chipset, which in theory is supposed to be picked up by the MPS driver, according to this web page: http://leaf.dragonflybsd.org/cgi/web-man/?command=mps§ion=ANY but instead it is picked up by the MFI driver...? What gives? ;) Is it that the MPS driver *and* the MFI driver both support the LSI SAS2108 chipset, but the MFI driver checks first during boot, so it wins?

Yeah, I believe it, my explorations of the MPS source code don't seem to indicate that particular PCI DEVID is listed as supported. It is for the MFI driver though. So, I guess the MFI driver just isn't fully stable with the Perc H700/H800 card. I'm punting here and going with a more supported Adaptec SAS controller. For whoever manages the FreeBSD MFI driver, it might be worth looking into this problem with the Perc H700 and H800, as more and more Dell configurations have them these days. Not that I'm complaining. I know this is all free software. ;) From owner-freebsd-scsi@FreeBSD.ORG Sat Mar 5 16:19:11 2011 Return-Path: Delivered-To: freebsd-scsi@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 32E461065672 for ; Sat, 5 Mar 2011 16:19:11 +0000 (UTC) (envelope-from stephane.lapie@darkbsd.org) Received: from quasar.darkbsd.org (shinigami.darkbsd.org [82.227.96.182]) by mx1.freebsd.org (Postfix) with ESMTP id A613E8FC0C for ; Sat, 5 Mar 2011 16:19:10 +0000 (UTC) Received: from quasar.darkbsd.org (localhost [127.0.0.1]) by quasar.darkbsd.org (Postfix) with ESMTP id 34C165F5B for ; Sat, 5 Mar 2011 17:00:57 +0100 (CET) DKIM-Signature: v=1; a=rsa-sha1; c=relaxed; d=darkbsd.org; h=message-id :date:from:mime-version:to:subject:content-type; s=selector1; bh=cGhhQ6w3/yi4KXKnM+MURFWR+qw=; b=w2J8ECot3Te1Oq58sRSaFl4ZuLbs s/AYbheH1Iyva/lyh+fnXtwECQQRuaPxkQ7pXNydH+RH6R4lERALM2ysPeHvcpyX Rzv2Safss2Qqu83dKvCeJ7WG+V/Vc+aZtWrNEFgPXk1x118oT803+Ros8fCNr0hu BcZ2xMGo4AmcVB8= DomainKey-Signature: a=rsa-sha1; c=nofws; d=darkbsd.org; h=message-id :date:from:mime-version:to:subject:content-type; q=dns; s= selector1; b=f3ESiRkr2sUEdIkzKfG/+vgIptBY/4ZMQNQKIWsFRQANtaD2IXW CfcInXG5oG+biTvPnNzXnQzlJ9171Y6NS2QSO7UUKjvzaz66LHyfuGkWNt9qwdO+ nrsuwyZHrAMBiM1BixJE5c5ZwRXIHz06wOKUzCUzVi/cJnzHA4v64NIA= DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=darkbsd.org; h= content-type:content-type:subject:subject:mime-version :user-agent:from:from:date:date:message-id:received:received; s= selector1; t=1299340854; bh=Y7MrDfyLU4sq6MRMQukWGfD00cVVl0XuMh49 wm/75e8=; b=jj/COybmT1e176JVyAq8WNUWYGYMyS2TePrA2XSqmHdxLzicyhrq nRsPp/5HP2nAWptvGUIExpZxcT02J+dsOpZh8knhLWcHy71S5320r9dkAPOcR+WE pEGk7L1JLNRgk5BWlXhIhGjL1qiCvkdmfm7Se7GKJmNd9wdf7v/+3Sc= Received: from quasar.darkbsd.org ([127.0.0.1]) by quasar.darkbsd.org (quasar.darkbsd.org [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id ApOdgbjHispF for ; Sat, 5 Mar 2011 17:00:54 +0100 (CET) Received: from [192.168.3.42] (l247136.ppp.asahi-net.or.jp [218.219.247.136]) (Authenticated sender: darksoul) by quasar.darkbsd.org (Postfix) with ESMTPSA id E7C515F52 for ; Sat, 5 Mar 2011 17:00:53 +0100 (CET) Message-ID: <4D725E27.7030803@darkbsd.org> Date: Sun, 06 Mar 2011 01:00:39 +0900 From: Stephane LAPIE User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.15pre) Gecko/20110207 Shredder/3.1.9pre MIME-Version: 1.0 To: freebsd-scsi@freebsd.org X-Enigmail-Version: 1.1.2 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="------------enig3DFC4AFFD35A4CE0BD70C608" Subject: Methods for collecting/managing SCSI/CAM/ATA error events X-BeenThere: freebsd-scsi@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: SCSI subsystem List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 05 Mar 2011 16:19:11 -0000 This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig3DFC4AFFD35A4CE0BD70C608 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello list, I just wanted to know if anyone knew of a proper method for handling SCSI events, such as a device reset, device not ready, illegal request, etc...
