If you issue the cfgadm -al -o show_SCSI_LUN controller-ID command immediately after a system boots up, the output might not show the Fibre Channel Protocol (FCP) SCSI LUN level information. The information does not appear because the storage device drivers, such as the ssd and st driver, are not loaded on the running 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(1M) command.
Log in as root (su - root).
Display the information about the attachment points on the system.
In this example, c0 represents a fabric-connected host port, and c1 represents a private, loop-connected host port. Use the cfgadm(1M) 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 host using the Solaris 10 OS.
Display information about the host ports and their attached devices.

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 hosts using the Solaris 10 OS. The Ap_Id devices with port WWNs under c1 represent private-loop devices that are configured through the c1 host port.
