POWER7 information

lsnports command

Purpose

Lists available ports that are capable of N_Port ID Virtualization (NPIV) and related information.

Syntax

lsnports [ -fmt Delimiter ] [ -field Fieldname ]

Description

The lsnports command displays information for all the ports capable of NPIV. If you use the name of the adapter driver (for a particular physical port) in the vfcmap command, the map_port attribute is set for a virtual fibre channel adapter on the server logical partition. This attribute maps the virtual fibre channel adapter on the server logical partition to a physical fibre channel port.

Without a flag, information is displayed in a column. Specifying the -fmt flag formats the output with a specified delimiter. If no NPIV ports are in the Virtual I/O Server logical partition, the error code E_NO_NPIV_PORTS(62) is displayed.

Flags

Flag name	Description
-fmt delimiter	Specifies a delimiter character to separate output fields.
-field	Specifies a list of fields to be displayed. The following fields are supported: name Physical port name physloc Physical port location code fabric Fabric support tports Total number of NPIV ports aports Number of available NPIV ports swwpns Total number of target worldwide port names supported awwpns Number of target worldwide port names available

Output Field Definitions

Field	Description
name	Physical port name
physloc	Physical port location code
fabric	Fabric support
tports	Total number of NPIV ports
aports	Number of available NPIV ports
swwpns	Total number of target worldwide port names supported
awwpns	Number of target worldwide port names available

Exit Status

Return code	Description
62	System does not have ports capable of NPIV.

Examples

To list all the NPIV-capable ports, type:

lsnports

The system displays the following message:

To list all the NPIV-capable ports in script format separated by two colons (::), type:
```
lsnports -fmt "::"
```
The system displays the following message:
```

```
To list specific fields (name, swwpns, and awwpns) of all the NPIV-capable ports, type:
```
lsnports -field name swwpns awwpns
```
The system displays the following message:
```
name    swwpns  awwpns
