I didn't, had to google. I see it listed on Kioxia's website as
CD6-V Series (6.4T model), but since customer was running on an
DL380 Gen10, I suspect it could also be HPE PE8030 (PN P19837-B21).


You can get more information about this controller using nvme-cli
id-ctrl command.

I'm aware.

I don't have access to the system, but id-ctrl output was shared with
us.

AFAICS these are the only identifying fields, which all indicate to be
Kioxia's:

NVME Identify Controller:
vid : 0x1e0f
ssvid : 0x1e0f
sn : [redacted]
mn : KCD6XVUL6T40
fr : GPK1
rab : 2
ieee : 8ce38e
...

Now something that I'm not aware. Would these change even if another
brand was using this Kioxia's chipset?

Is it crucial to have the product information (vs only chipset information)
for quirks? I'm already querying the customer for this anyway.


Cheers,

Enzo
