Somehow I did not receive original post.
I believe it is because of DMARC setup - got some DMARC reports. That'll require another topic or some research.

Hello group,
I am trying to evaluate use of fibre channel switched fabric. But I am not able to get it working (openSUSE Leap 15.1).
That's not enough to even start guessing. Explain what you did, what you expected and what you got.
I connected a Server running openSUSE Leap 15.1 with a FC HBA built-in to a switch connected also to a FC Disk Shelf. Using AVAGO 850nm SFPs and orange LC-LC optical cables if I remember correct like that: HBA Port 1 2 | | Switch Port 1 2 3 4 | | Shelf Contr. 1 IN OUT Contr 2 IN OUT (do not know if it was in the jack named "IN" or "OUT", but I do remember, only one version worked, i.e. the devices and the hard drives showed up on the switch. Controller was set to default values: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++/------------------Selected Adapter-------------------------\++++ +++++| Adapter Type Address Slot Bus Device Function |++++ +++++| HPAE312A 4000 01 01 00 1 |++++ +++++\-----------------------------------------------------------/++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++/-----------------Adapter Settings--------------------\+++++++++ ++++++| |+++++++++ ++++++| BIOS Add/----------------------------------------------------\ ++++++| BIOS Rev| Option Type of Connection | ++++++| Adapter | | ++++++| Interrup| 0 - Loop only | ++++++| Adapter | 1 - Point to point only | ++++++| Host Ada| 2 - Loop preferred, otherwise point to point | ++++++| Frame Si\----------------------------------------------------/ ++++++| Loop Reset Delay: 5 |+++++++++ ++++++| Adapter Hard Loop ID: Disabled |+++++++++ ++++++| Hard Loop ID: 0 |+++++++++ ++++++| Connection Options: 2 |+++++++++ ++++++| Fibre Channel Tape Support:Enabled |+++++++++ ++++++| Data Rate: 2 |+++++++++ ++++++| |+++++++++ + Use <Arrow-keys> and <Enter> to change settings, <Esc> to exit I expected, that those HDs can be accessed (or even found) on the server. Loopback data test using the Fast!UTIL works. also the WWNs of the HDs show up in dmesg. But I cannot access/find these devices in the OS or Fast!UTIL
I would appreciate,
if anybody knows something or where to find (working) instructions. All instructions I found refer to old/or proprietary drivers/methods (kernel 2.6 or older).
I have no idea what you are talking about. FibreChannel normally just works. The only potential setting is protocol (FC-AL or point-to-point) and HBA usually tries both so it just works.
You need to make sure you are using the same type of SFP and cables (MMF vs. SMF) everywhere.
I use following hardware: -HP branded (AE312 - 60001) QLogic Corp. ISP2432 4G HBA PCIe
Should just work.
-IBM branded (2005-B16) Brocade 200E 16 Port FC switch
That should be 4G so compatible with 4G HBA. You would need to either remove zoning completely (so each device see each device) or create zones for your HBA and storage devices.
tried previously without zoning and tried again with zoning disabled. no success
-DS14MK2 Disk Shelf
That's not a storage. It is disk shelf for NetApp FAS (very old models) and was never intended to be used as direct JBOD. This only supports FC-AL protocol and I do not know whether it supports fabric attachment (it has no reason to support it). So the first thing to test would be to connect it directly, without switch. If HBA sees disks and you insist on using switch, Brocade supports QuickLoop which simulates FC-AL between different ports. It may work.
I couldn't yet find out how to set up quick loop (using the GUI no devices show in the selection list). First I try the setup without switch.
All of those products are EOS and I am not able to get proprietary drivers or firmware updates.
HBA should work with upstream driver, FC switch usually just works as well (there is very little reasons to upgrade unless you hit specific bug or need additional features). DS14mk2 could be an issue though. Also native NetApp disks are 520bps which may or may not be a problem.
I know, but having built-in "normal" hard disks. These show up in the switch-ui. According to a source, I do not remember, it should just work plug and pray..
Anyway, start with explaining what exactly you did and what "does not work" currently.
Somehow I still do not receive messages from OP, but looking in archives 16 0 id N2 Online L-Port 9 public, 7 private 17 1 id N2 Online L-Port 6 public, 10 private this confirms what I wrote. These two ports cannot talk with other ports on switch. Try direct connection first.
that is what I thought the switch is (also good for), not to be restricted to the Loop-setup. Also according to the GUI that should work. IIRC, I also read, that someone did a Firmware Upgrade on th DS14mk2, which also enabled use of N-Ports (?). The controllers do have a console plug, but with PS/2 connectors(?). I didn't find out how to connect to RS-9 correctly. But, what you wrote, may be right, as that would explain everything. But HBA should support P2P and Loop. I tried direct connections: HBA Port 1 | Shelf Contr 1 IN OUT | Shelf Contr 2 IN OUT Fast!UTIL: loopback test works. scan devices doesn't show any. OS: nothing found (lsscsi / rescan-scsi-bus.sh) rmmod/modprobe: https://www.swabian.net/extern/opensuse/fcdmesg2.txt connected in another way: HBA Port 1 | Shelf Contr 1 IN OUT | Shelf Contr 2 IN OUT no change. https://www.swabian.net/extern/opensuse/fcdmesg3.txt Thank you for your support so far. I do not have experience with FC besides this case. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
