Beware of EMC switches sold as Mellanox SX6XXX on eBay

[klui]

Your logs don't show any critical errors. Did I miss something?

If you've followed the guide and your loglevel is set to 2 you won't see ECC errors during boot. The odd thing for me is the recovery partition won't show any kernel messages with loglevel set to 2.

Maybe for you a reinstall is in order.

 

[neggles]

My bad, I forgot to even mention the actual issue ‍*facepalm* it refuses to identify any optics/DACs; they all show as "unsupported module" or "invalid/missing EEPROM data in module".

I did once manage to get it to identify a genuine Mellanox 40G IB DAC, but it won't even identify that anymore, or any SFP+ modules installed in a QSA. It also takes it a solid two or three minutes to load the sx6012 [standalone: master] > prompt after logging in.

The boot log doesn't look any different with loglevel=4 either, guess I should try five or six, or just accept that the blown fan chip's messed up some other stuff too.

[Edit:] I would really, really appreciate a known-good switch's printenv output, though. If anyone feels like passing theirs on, feel free to remove any values that identify the specific switch if that concerns you - placeholders like <serial> or <mac> are totally fine.

Here's mine. I just x'ed out ethaddr and eth1addr MACs. Not sure how to turn off emojis. addip is "s e t e n v . . . { n e t d e v } : o f f p a n i c = 1"

[neggles]

Thanks a bunch; (un?)fortunately I'm not missing anything, but it's good to be sure.

That said, oh my god, I'm an idiot. Remember a few posts back where I showed how to flash from within the CLI fae menu?

This line is wrong:

sx6012 [standalone: master] (fae) # flint -allow_psid_change -override_cache_replacement -d /dev/mst/mt51000_pci_cr0 -i /tmp/user.md5sum b

Correct device path (for mine at least) is /dev/mst/mt51000_pciconf0. Reflashed, reinstalled, and it works now. Yay!

 

[klui]

Good to know you got it fixed and informed the thread. Was it force of habit of using pci_cr0 for their NIC cards? mst status doesn't show that device. Only dev-i2c-[0-9] and mt51000_pciconf0.

 

[neggles]

I think I saw it listed under one of the other status commands... *sigh*

It's still very unhappy about the fans all being dead, but it's not generating 10MB of syslog messages every few minutes, so that's a plus.
It also still won't recognize any SFP+ modules installed in a QSA... but it does identify the Mellanox Infiniband DAC

I also only get two i2c devices on initial boot;

MST modules:
------------
    MST PCI module loaded
    MST PCI configuration module loaded

MST devices:
------------
/dev/mst/dev-i2c-0         - Embedded I2C master
/dev/mst/dev-i2c-1         - Embedded I2C master
/dev/mst/mt51000_pciconf0        - PCI configuration cycles access.
                                   domain:bus:dev.fn=0001:81:00.0 addr.reg=88 data.reg=92
                                   Chip revision is: 02

I get all of them once I do an 'mst restart'... tc and hwd are also pretty upset at my PSU/fan situation;

These messages repeat over and over; at this point it's probably fairly safe to say this is a hardware problem, though.

 

[klui]

At least the system doesn't shut down.

You may want to consider redirecting all that to a remote server otherwise it will just wear out your flash.

 

[neggles]

Yeaaaah, it's pretty much toast. Something's screwy with the i2c buses, which are on the SwitchX chip and/or the Lattice CPLD, and there's nothing obvious I can find other than a couple of blown zero-ohm resistors that shouldn't be relevant (and replacing didn't fix)

Ports 1-4 don't work, ports 5-6 do, 7-8 don't, 9-12 do.

Amusingly, putting an optic in port 4 makes it report one of the fans is working at 18,000rpm; these are 3000rpm fans

Replacement time! But hey, now I know exactly what to do to the next one.

Hi,

Greate post, thank for every one involved.

I am migrating reflashing 2 6012.
1st one is - OK - i was able to reflash it (it take some time, but it is working)

But, i am stuck on 2nd.
I try 1002 and 8012, everething ok till 6.2.b, i am booting to MLNX-OS, but admin/admin didn't work.


removing and/or modifing /mnt/root2/etc/passwd didn't help.

klui
I was able to find solution.

I gor 2 switches ...

And seems 1st is ok to upgrade using standart guid.
2nd work only with chrood upgrade. When I remove/change link to passwd file - i can't login.

So seems like
Step 6.2.C
keep passwd and shadow as is

Upgrade system using chroot method from #372
reboot, login using admin/admin


And was able to upgrade to 1002 and 8012.

But still got a question.
The Plan is to use switches as IB FDR (56G).
I got several DAC cables some of them got MAX speed info


But some of them not

Infiniband speeds : unknown

The problem is that i got 40G QDR all the time - on clevre and stupid cables

Does any one able to use them as 56Gb IB with non original Cables?


P.S. I got 56G Cards and 2nd switch

 

[Eong]

I'm kind of surprised that nobody's discovered this hidden menu yet, but here's a fix for that;

configure terminal
fae cable-stamping-unlock 40g_lr4
exit
write memory

Not 100% sure I remember that right, but fae cable-stamping-unlock ? will show you the available unlocks - there's one other, which IIRC allows using 56Gb rates over 40Gb-rated DACs.

The fae menu has an awful lot of fun commands hidden inside; It doesn't show up in a regular ? or help listing, but if you type fae ? while in configure mode, it'll list out (most of) the available commands. I believe flint is included - not sure, my switch is re-imaging itself after I messed up the latest conversion attempt - along with a number of other executables in the base linux OS and a whole bunch of fun debug/manufacturing commands.

Be careful. Several of the commands in here can near-irrevocably break your switch.

I was too busy in the past few weeks with my project and I didn't visit forum.
I also found that and it fixed my issue. All the LR4 transceivers I have work without any problem.
Thanks for the tips anyway.
Did you figure out how to remove the minimal requirement of the fan speed?

I can't remember the specific command, but fae cable-stamping-unlock ? at the configuration prompt should give you a list of two options. One is 40g_lr4, the name of the other one implied that it would unlock 56G over unsupported cables.

Yep, already done - But the only option is to enable fdr10.
And after that i got fdr10, but still - 40G



I got same problem on 8012, but seems i am not able to get correct GID - as license is empty.
Now i am on 1002 - license is ok, but still no Full FDR

P.S. regurding 8012 - what is correct way to get 12 digit hex for hostid GUID from switch label didn't work (as it 16 digits)

Any digits will work. Like 010101010101.

I try 2 time on 2 switches - The license page is empty

Is it OK ?

I think it means that non mellanox qsfp14 cables can be used with that switch.

Nope, there is only fdr10, so you can't unlock 56 FDR.

fae cable-stamping-unlock ?
<type> Cable or transceiver speed

You need a cable or optical transceiver physically support FDR 14/56G speed, even you have a license actived the switch 56G speed.

So, yes i do understand ... But.
I do understand why clever QDR cables didn't work with FRD10, but i don't understand why stupid cables can work with FRD10.

So basicly the major question - Does anyone have stupid QSFP cable with FDR/56G ?
