Beginning in ONTAP 9.14.1, host discovery of controllers using the NVMe/TCP protocol is automated by default in IP-based fabrics.
Enable automated host discovery of NVMe/TCP controllers
If you previously disabled automated host discovery, but your needs have changed, you can re-enable it.
Steps
-
Enter advanced privilege mode:
set -privilege advanced
-
Enable automated discovery:
vserver nvme modify -vserver <vserver_name> -mdns-service-discovery-enabled true
-
Verify automated discovery of NVMe/TCP controllers is enabled.

Disable automated host discovery of NVMe/TCP controllers
If you do not need NVMe/TCP controllers to be automatically discovered by your host and you detect unwanted multicast traffic on your network, you should disable this functionality.
Steps
-
Enter advanced privilege mode:
set -privilege advanced
-
Disable automated discovery:
vserver nvme modify -vserver <vserver_name> -mdns-service-discovery-enabled false
