Overly long lines here, but I can fix that up.
Missed that, sorry. Thanks.
 Do you have a product
name for this device or is just a nameless OEM controller?
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).


Cheers,
