Question Image

A customer has an AFF A700 connected to a Cisco switch and has confirmed connectivity, but cannot view any LUNs. To verify the connection, the customer ran the run -node scaling-01 -command fcp topology show command.

Referring to the exhibit, what must be enabled on the Cisco switch?

Explanation

ONTAP FC logical interfaces (LIFs) use N_Port ID Virtualization (NPIV) to log in as separate virtual N_Ports over the controller's physical FC adapters. If NPIV is not enabled on the connected Cisco switch, the controller's virtual FC ports cannot log into the fabric even though the physical adapter itself establishes a link, which is why connectivity can be confirmed at the physical layer while no LUNs are visible to the host; enabling NPIV on the switch allows the virtual N_Port logins to succeed.
