Hi,

The SPDK nvme bdev module listens for asynchronous event notifications (AENs).  A well-functioning NVMe controller will send an AEN to the host when namespaces have been attached.  When the nvme bdev module receives the AEN, it will automatically rescan the nvme controller and register any new namespaces 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 bdev?It is easy to re-attach again, but the former namespaces(bdev) are in-using.
Thank you
