Hi
I think the host nqn file should exist even before the first connection attempt, so
That a management software will be able to first configure the storage to allow connection from this nqn(with ACL).
The rpm spec can run a script during first install to take care of that.

Thanks

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 ?

Yes, I would say that if nvme-cli is told to use /etc/nvme/hostnqn and the filename is not there for nvme-cli to create the file containing a generated hostnqn per NQN naming standard in the NVMe spec.

Hi

Hey Gili,

quoted

I was wondering if there's a special reason why not to support 
preconfigured initiator nqn from a file.
(similar to iscsi in /etc/iscsi/initiatorname.iscsi).

It was raised on the list just last week. I think Jay has (of was
:))
volunteered.

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:

http://lists.infradead.org/pipermail/linux-nvme/2016-July/005562.html

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