Hi,

The SPDK nvme bdev module listens for asynchronous event notifications (AEN=
s).  A well-functioning NVMe controller will send an AEN to the host when n=
amespaces have been attached.  When the nvme bdev module receives the AEN, =
it will automatically rescan the nvme controller and register any new names=
paces as bdevs.

Best regards,

Jim

Subject: [SPDK] Can nvmeof device add more namespaces(bdev) dynamically?
Hey guys,
I have a question.
The  bdev_nvme_attach_controller  add all namespaces of this nvme as bdevs.=
I have created some namespaces attach to  system,  then I create more ns at=
 the same nvme later. How can I re-scan the nvme ctrl  new namespace as bde=
v?It is easy to re-attach again, but the former namespaces(bdev) are in-usi=
ng.
Thank you
