A system with more than one of these SSDs will only have one usable.
Hence failed to detect nvme devices due to duplicate cntlid.
[ 6.274554] nvme nvme1: Duplicate cntlid 33 with nvme0, rejecting
[ 6.274566] nvme nvme1: Removing after probe failure status: -22
After adding to the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk resolves the issue.

Can you send me a dump of nvme id-ctrl /dev/nvmeN for this device?
I'm mostly curious on what spec version it claims compliance to,
and what is stored in the subnqn field.

So it claims 1.2.1 compliance, and the NQN looks like a valid one.
And that NQN is the same for multiple devices? Or is this one PCIe
device with multiple functions that report the same controller ID?

These are two different devices. Only one of the two NVME devices is seen. The other device is rejected due to “Duplicate cntlid”.
Thanks

So two card with one controller each, and both have the same subnqn.
Ok. I guess the quirk is exactly right in this case, although I would
not have expected this bug from an enterprise drive from a somewhat
reputable vendor.

And it has CMIC capabilities! The quirk means we're using driver
generated nqn's for multipath detection, so it won't work with
multipath: the fake nqn uses the controller serial number, so all the
controllers in the subsystem will get different nqn's.

SN is uniqueue for the whole subsystem:
"Contains the serial number for the NVM subsystem that isassigned by the
vendor as an ASCII string."
