Hello

I'm using nvmetcli version 0.7 on OpenSUSE  LEAP 15.5

I have problem with FC transport. When i'm trying to add subsystem in fc 
port configuration I get error

Could not symlink testnqn in configFS: [Errno 6] No such device or 
address: '/sys/kernel/config/nvmet/subsystems/testnqn' -> 
'/sys/kernel/config/nvmet/ports/2/subsystems/testnqn'

In attachment there is json with my configuration.

Can you please help me ?

You are using downstream version of nvmetcli and the kernel, maintained
by your distro vendor. In this case you should report the problem there
(bugzilla.opensuse.org).

Here on this mailing list, we ask you to try with current upstream
version to reproduce the problem, e.g. nvmetcli 0.8 and the latest
release upstream kernel v6.8.x. If you still observe your problem, feel
free to post your results.

Thanks,
Daniel

I've tried once to get a P2P setup with QLogic cards but failed. IIRC,
I run into troubles with the QLogic firmware not be able to act as
target. I'd suggest you enable the debug logs of the qla2xxx driver.
There might be a hint what's going wrong.

HTH,
Daniel

Quite simple: the qla2xxx driver doesn't support nvme-target.

There was a patch once, but never made it upstream. Blame Marvell.
