How to Detect Visible Fabric Devices on a System

This section provides an example of the procedure for detecting fabric devices using FC host ports c0 and c1. This procedure also shows the device configuration information that is displayed with the cfgadm command.

Note - In the following examples, only failover path attachment point IDs (Ap_Ids) are listed. The Ap_Ids displayed on your system depend on your system configuration.

Become an administrator.
Display the information about the attachment points on the system.
```
# cfgadm -l
Ap_Id                Type         Receptacle   Occupant     Condition
c0                 fc-fabric      connected    unconfigured unknown
c1                 fc-private     connected    configured   unknown
```
In this example, c0 represents a fabric-connected host port, and c1 represents a private, loop-connected host port. Use the cfgadm command to manage the device configuration on fabric-connected host ports.
By default, the device configuration on private, loop-connected host ports is managed by a system running the Oracle Solaris OS.

# cfgadm -al
Ap_Id                Type      Receptacle     Occupant   Condition
c0                 fc-fabric   connected    unconfigured unknown
c0::50020f2300006077 disk      connected    unconfigured unknown
c0::50020f23000063a9 disk      connected    unconfigured unknown
c0::50020f2300005f24 disk      connected    unconfigured unknown
c0::50020f2300006107 disk      connected    unconfigured unknown
c1                 fc-private  connected    configured   unknown
c1::220203708b69c32b disk      connected    configured   unknown
c1::220203708ba7d832 disk      connected    configured   unknown
c1::220203708b8d45f2 disk      connected    configured   unknown
c1::220203708b9b20b2 disk      connected    configured   unknown

Note - The cfgadm -l command displays information about FC host ports. You can also use the cfgadm -al command to display information about FC devices. The lines that include a port world wide name (WWN) in the Ap_Id field associated with c0 represent a fabric device. Use the cfgadm configure and unconfigure commands to manage those devices and make them available to systems using the Oracle Solaris OS. The Ap_Id devices with port WWNs under c1 represent private-loop devices that are configured through the c1 host port.
