As far as I know, there should be written a middleware because of the raid disk type and the lun numbers. Because thats my first kernel project and I'm not shure how and where into the scsi framework this should be implemented, I as for some guide/hints/whatever; and yes, I'm able to code and understand C.

It should be a SCSI upper-level driver like sd.c, sr.c, st.c and osst.c. It may make most sense for it to be implemented as a part of sd.c, or it might be better to do it by implementing a new raid_sd.c. > at which kernel version in detail the patch should apply? > (sorry, I'm new). Start with 2.6.16-rc5 (the most recent release by Linus). It shouldn't be much effort to forward-port it whern it comes to merge it. ^ permalink raw reply [flat|nested] 46+ messages in thread

What is PDA and VSA? And.. have some more probs (was a little bit too fast), perhaps you have an idea: When I dd more than 556k bytes to the drive, I get errors.

Attached. But "special" ugly hack, far away from final code.

Perhaps someone could have a look at that? Or give me tips how to decode a CDB or point me to the right scsi standard link? I have attached logs from a working and a not working transmission. _Please_ have a look at it, because I have no more ideas where to find my problem. bye, ingo flaschberger geschaeftsleitung crossip communications gmbH ------------------------------------------------------------------_------------ sebastian kneipp gasse 1 _____ _____ ____ _____ _____ (_)____ a-1020 wien / ___// ___// __ \ / ___// ___// // __ \ fix: +43-1-726 15 22-217 / /__ / / / /_/ /(__ )(__ )/ // /_/ / fax: +43-1-726 15 22-111 \___//_/ \____//____//____//_// .___/ mob: +43-699-105 86 719 _______ / / www.xip.at communications gmbh /______//_/ ------------------------------------------------------------------------------- [-- Attachment #2: Type: TEXT/PLAIN, Size: 28835 bytes --] Mar 28 22:41:46 localhost kernel: sd_init_command: disk=sda, block=4207, count=8 Mar 28 22:41:46 localhost kernel: sda : block=4207 Mar 28 22:41:46 localhost kernel: sda : reading 8/8 512 byte blocks.

If I read your code correctly last week, all you've done so far is mess with LUN scanning. And my guess is things blow up when you've queued enough I/O and things start actually hitting the metal. The real problem with the RA4100 is that you can't just send commands (cdbs) to it directly. You need to mangle them and this is what we currently have no good infrastructure to support. The RA4100 supports two addressing modes VSA and PDA and depending on which mode is used you need to mangle the cdb in different ways. Judging from the comments in cpqfc it appears the mode depends on the firmware of the RA4100 in question. Below is what I sent to hch about the RA4100 a while ago... Btw. SCC is the SCSI Controller Commands specification - i.e. TYPE_RAID. The spec is at http://www.t10.org/ftp/t10/drafts/scc2/scc2r04.pdf ---8<--- The LUN mangling takes place in cpqfcTSworker.c. Here's what happens: - IssueReportLunsCommand() gets fired off to send a REPORT_LUNS to the array SCSI ID. - ScsiReportLunsDone() is called upon completion. If REPORT_LUNS failed we need to use peripheral device addressing (PDA) and set VolumeSetAddressing (VSA) to 0. If REPORT_LUNS succeeded VSA is set to 1 and so is LunMasking (which is a kludge becase we didn't do sparse LUNs). - fcFindLoggedInPort() is a swiss army knife function that gets called all over the place in cpqfc. It deals with mappings between WWNs/port ids and SCSI channel/target/lun tuples. In this case we need to map a Linux LUN to a fibre channel ID (AL_PA or WWN) Look for /* This is not passthrough */ in that function: The Scsi_Cmnd in transit has a few things changed. Specifically, the scratch pad is abused: - Cmnd->SCp.phase is set to contain either PDA or VSA - Cmnd->SCp.Message is set to contain the device type snooped from INQUIRY (check out cpqfcTSCheckandSnoopFCP()) - Cmnd->SCp.have_data_in is set to the real LUN So far so good. Now we've got some extra fluff in the Cmnd. On to... - build_FCP_payload() which picks these pieces out of the supplied Cmnd and builds an FCP transfer with the SCC addressing gunk prepended to the cdb. Now, all the sparse LUN stiff is obsolete. And the only place the stored inquiry data is being used is to special case timeouts when dealing with tape devices. So the only state we need to keep is the real LUN # and the addressing mode (VSA or PDA are probably the only relevant ones). Given that we can use the LUN value directly, all we need to do is to get the addressing blah prepended. ---8<--- -- Martin K.

Following things I changed in the kernel: *) To find the devive: Lun scan code in scsi_scan.c Device special flags in scsi_devinfo.c The final implementation could be easy done via the flags in the scsi_devinfo.c file. *) The RM4000 make troubles when trying to write more than 1023Kbytes in one cdb. I have changed sd.c to avoid this and only use 512Kbyte blocks as maximum. The final implementation is a little bit difficult because I need some flags to detect the block size problem in sd.c, sd_init_command. Should I build the changed into sd.c?

Ans thats was why I used the BLIST_REPORTLUN0 before, because using BLIST_REPORTLUN2 (try REPORT_LUNS even for SCSI-2 devs) is not very "logic" for SCSI_UNKNOWN devices...

OK, try this out. It places the sector limit in the block queue. I also removed all the superfluous condition braces and tried to change the comments to match what you're doing (the block size is actually in multiples of 512 bytes, so the limit you impose is actually 512 *blocks* or 256kB).
