How do I list built-in fibre channel devices on some sun systems? *

petulia3478

On some SUN systems there is a build in fibre channel loop, this normally controls the internal fibre channel disks. The act as JBODS, which stands for "just a bunch of disks". To interigate the devices on this fibre channel loop the command luxadm is used, this was also used on some older storage arrays like the A5000 series.

To search for fibre channel device connected to the built-in fibre channel loop:

# luxadm probe
Found Enclosure:
SUNWGS INT FCBPL Name:FCloop Node WWN:5080020000220888 Logical Path:/dev/es/ses0

To display the devices on this node, World Wide Node Name, do:

# luxadm display -v 5080020000220888
