Configured nqn

[Gili Buzaglo]

Hi
Sorry for responding late.
My original thought was that the nvme-fabrics driver will initiate the nqn from the file,
But your suggestion is also suitable and less complex.
Who is responsible for creating the file  /etc/nvme/hostnqn ?
Maybe nvme-cli first installation ?

Thanks

I was going to do it, but I was waiting for a reply on confirming what behavior people wanted to see:


"So is the request to have nvme-cli use whatever is in /etc/nvme/hostnqn (if it exists) over the default in the nvme-fabrics driver?  So preference of hostnqn input would be:

1. --hostnqn flag
2. /etc/nvme/hostnqn
3. default hostnqn generated by nvme-fabrics driver (ex: nqn.2014
-08.org.nvmexpress:NVMf:uuid:a2d7752c-a31b-477a-a003-31a5e1c424a9)

(note 2. may contain a hostnqn different from the default)"


Gili if you are itchin' to do it, go ahead and give it a shot, just let me know (or I can still do it w/confirmation to above).  The discovery fix I added to nvme-cli:

has been merged into the nvme-cli tool by Keith.
