Although ONTAP uses a NVMe/FC LIF that is separate from the FCP LIFs, both LIFs can be hosted on

the same physical HBA port at both the host initiator and storage target. NVMe/FC and FCP can

share the same physical infrastructure concurrently, so the same physical port, cable, switch port,

and target port can simultaneously host and transmit both FCP and NVMe/FC frames

NVMe can use the same FC infraestructure, but it needs to create a separate NVMe LIF to work.

Because NVMe/FC simply swaps command sets from SCSI to NVMe, it is an easy transition to make.

NVMe/FC uses the same FC transport and therefore the same hardware from the host, through the

switch and all the way to the NVMe/FC target port on the storage array. Thus, NVMe/FC

implementations can use existing FC infrastructure, including HBAs, switches, zones, targets, and

cabling.

We can discard that ANA was not properly configured becase this is not a problem about

multipathing.

We can discard WWPN because this is an NVMe configuration where WWPN is not involved

We can discard that NVMe was not configured because we wouldn't be able to even run that

command if that's true

Configure the NQN correctly is one of the steps when we configure NVMe

Depending on what is selected in the "Trigger" option, Snapshot Autodelete will automatically delete

a snapshot when, either the volume space utilized, or the snapshot reserve reaches a threshold

capacity

specified below.

Automatic deletion of Snapshot copies from flexible volumes Data ONTAP can automatically delete

one or more Snapshot copies on the volume, provided the Data ONTAP Snapshot copy autodeletion

policy is enabled and set to trigger when the overwrite reserve is nearly full on the volume.

FLI does not support iSCSI connections directly. In order for iSCSI LUNs to be migrated using FLI, the

LUN type must be changed to FC. After the migration is complete, the LUN type is changed back to

iSCSI.
