The controller isn't the problem, it's CAM.

I for one am not using it for anything but RAID volumes. I would never try to use a RAID controller for anything but RAID volumes (or even JBOD) anyway. You can't use non-disk devices with any of the other non-CAMified RAID controller drivers, can you? If you disable non-disk devices in mly, most people would assume that RAID controllers just don't/shouldn't do non-disk devices, at least in FreeBSD. If you think it would piss anybody off, make it a compile-time option wether or not the mly driver supports non-disk devices. Or even better, a sysctl tunable that can be set from the loader, just like hw.ata.* (hw.mly.cam_nondisk_filter?). My vote would be to _not_ support non-disk devices by default, but that might break POLA. :-) > Please, someone actually acknowledge that they're hearing me on > this?

I forgot you could turn off the new behaviour with a sysctl, if I actually implemented it correctly. In the loader before boot, or in /boot/loader.conf, put: hw.mly.cam_nophyschans="0" and try again.

Now i have another one though, we are currently planning to purchase some new servers and the SGI 1200 servers look pretty good and we have gotten a great price on them so i was wondering if anyone could help my find out whether or not FreeBSD could run on these servers and use the backplane in it. Here's some info on it: "The SCA midplane uses Qlogic's GEM processor to implement the SAF-TE (SCSI Accessed Fault Tolerant Enclosure) specification." I dont know if this is enough information so here's a link to some more info: http://techpubs.sgi.com/library/dynaweb_bin/ebt-bin/hdwr/nph-infosrch.cgi/in fosrchtpl/SGI_EndUser/1200_UG/@InfoSearch__BookTextView/717;he=0?DwebQuery=1 200 And you can search for "1200" at http://techpubs.sgi.com/library/tpl/cgi-bin/browse.cgi and find even more info. It might be possible that i can get a server to put FreeBSD on before we buy these and test it, but i dont know yet. I know this isn't really a lot of informatio to find out, but if anyone could give me any sort of info on how i might get it working or whether or not it would work i would be a very happy little boy :) Michael Aronsen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Thu May 31 8:18:49 2001 Delivered-To: freebsd-scsi@freebsd.org Received: from mx0.gmx.net (mx0.gmx.net [213.165.64.100]) by hub.freebsd.org (Postfix) with SMTP id 0F48737B422 for ; Thu, 31 May 2001 08:18:44 -0700 (PDT) (envelope-from msmeyer@gmx.net) Received: (qmail 2456 invoked by uid 0); 31 May 2001 15:18:39 -0000 Date: Thu, 31 May 2001 17:18:38 +0200 (MEST) From: Markus Meyer To: freebsd-scsi@freebsd.org Cc: msmeyer@gmx.net MIME-Version: 1.0 Subject: again: mly driver and enclosure devices X-Priority: 3 (Normal) X-Authenticated-Sender: #0000458190@gmx.net X-Authenticated-IP: [62.225.210.128] Message-ID: <14593.991322318@www24.gmx.net> X-Mailer: WWW-Mail 1.5 (Global Message Exchange) X-Flags: 0001 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hi, as described by Clemens (haribeau@gmx.de) and others some mails before there's a problem when using the backplane ESG-SHV SCA HSBP M14 (enclosure device) together with the mly driver. It's not really clear what happens, but it seems like the mly driver communicates with the backplane in a wrong way, which causes the backplane to go to offline mode. In offline mode, automatic rebuild and other functions will not work. This is represented by error messages on bootup. I am really no SCSI expert, but some days ago I wrote a short patch that prevents the backplane from communicating with the driver. Each IO message is tested against a hardcoded target and lun number and if it matches, the message will not be processed any further. That solved the problem (at least at first glance), but simply ignoring the messages seemed like a bad hack to me, and hardcoding the target and lun numbers in the code is also not nice. In the meantime, Mike and others supplied some suggestions and patches, but we tested these and they did not work. Mike had the idea of returning a timeout state within the device inquiry, to stop the enclosure from doing any further requests. But this does not work, because the inquiry seems to be for the logical devices, and the backplane does not do any inquiry at all. Another problem is, that I cannot find a way to detect, which device is the enclosure. I added a lot of debug messages and dumped the mb_type and mb_name fields, and other fields that could give a hint, which one is the enclosure device, but without any result. We finally decided to use the patch below. If anyknow knows how to automatically detect the enclosure device, or if simply ignoring all message from the device is harmful, please let me know. I am not a member of the list, so please reply with my email adress in the CC field.

Could some kind soul help me designing an expensive but good SCSI RAID solution ? Its the only FreeBSD system but I hope I can attract customer .... Want to build up a not too expensive RAID system for my customer. FreeBSD machine currently is a 4.0-20000715-STABLE machine, which will be upgraded to FreeBSD 4.3-STABLE soon. Currently I have an Adaptec Wide SCSI controller builtin: ahc0: port 0xf400-0xf4ff mem 0xfedfe0= 00-0xfedf efff irq 7 at device 19.0 on pci0 ahc0: aic7880 Wide Channel A, SCSI Id=3D7, 16/255 SCBs I want a separate RAID controller in a separae case, which offers hot plug capability and optional hot spare disk. I want to connect the external raid tower to the Adaptec like a separate disk. I think of 3 disks doing RAID level 5 and perhaps one "hot spare" that automatically jumps in, if one disk is misbehaving. There should be a possibility, that one gets an hearable warning or over another notifi= cation, so that you can automate the process of notifying administrator via e-m= ail. I=B4m looking for a complete solution, which I can buy in Germany, if i= ts possible. If not possible, then single components. One SCSI channel would already= be satisfactory, dual channel would be o.k. as well. Any help would be highly appreciated.
