Managing NPIV Ports

Language:

You can configure NPIV for non-virtualized environments by using the fcadm command.

You can use fcinfo and fcadm status commands to determine the status of NPIV ports, regardless of whether the ports are created by using the fcadm command. These commands also report the relationship between the physical port and the virtual ports hosted on a specific HBA port.

Other FC commands, such as cfgadm, report NPIV information, although no distinction is made between virtual and physical ports.

How to Create an NPIV Port

Before You Begin

Each virtual port must have a port name and a node name. The port name must be unique on the SAN. You can assign names manually or use the built-in random WWN generator. If you attempt to register duplicate names, most switches will report an error status on the newly registered WWN, and the switch will not register the new WWN.

For more information about acceptable name formats, refer to the T11 standard: Fibre Channel Framing and Signaling (FC-FS 2).

If you try to create an NPIV port on an HBA that does not support NPIV, an error will occur. If you try to create an NPIV port on an HBA that supports NPIV but is attached to a switch which does not support NPIV, the port will be created with an offline status. The status will be reported in the fcinfo output.

Create an NPIV port.
```
# fcadm create-npiv-port -p Virtual_Port_WWN -n Virtual_Node_WWN 
PhysicalPort_port_WWN
```
If you omit the –p and –n options, a random WWN will be assigned for the virtual port and virtual node.

Example 10 Creating an NPIV Port

The following example creates an NPIV port on a physical HBA port with a WWN of 2100000e1ec95100, a virtual port WWN set to c300000000005100, and a virtual node WWN set to c0007d32aa4c2b59.

# fcadm create-npiv-port -p c300000000005100 -n c0007d32aa4c2b59 2100000e1ec95100

How to Display NPIV Port Status

Display the currently configured NPIV ports.
```
# fcinfo hba-port
```
The NPIV port list shows the list of currently configured NPIV ports.

Example 11 Displaying the Status of NPIV Ports

The following example shows that HBA port 2100000e1ec95100 has three virtual ports.

How to Delete an NPIV Port

Before You Begin

You can use the fcinfo hba-port command to display the current WWN values for the NPIV ports. For more information, see Displaying Fibre Channel Devices.

Delete an NPIV port.

# fcadm delete-npiv-port -p Virtual_Port_WWN PhysicalPort_port_WWN

Example 12 Deleting an NPIV Port

The following example deletes an NPIV port on a physical HBA port with a WWN of 2100000e1ec95100.

# fcadm delete-npiv-port -p c300000000005100 2100000e1ec95100
