To identify attached A5X00 enclosures, "luxadm probe" is used. 
In most instances, the output from luxadm probe will show the 
enclosure name as well as its ses devices, like you see below.

# luxadm probe
Found Enclosure(s):
SENA               Name:A5200B   Node WWN:508002000002dc90
  Logical Path:/dev/es/ses0
  Logical Path:/dev/es/ses1
  Logical Path:/dev/es/ses4
  Logical Path:/dev/es/ses5
 
 With this particular problem, 'luxadm probe' fails to identify 
the enclosure and corresponding ses devices.  Instead, no
Network Array enclosures are found and the path to the fiber
channel disks are shown.

#luxadm probe
Network Array enclosures found in /dev/es
Found Fibre Channel device(s):
  Node WWN:20000020370f448d  Device Type:Disk device

  ......                              

  This document assumes there are no hardware issues causing the 
problem. It may be a good idea to rule out a hardware issue 
by other troubleshooting techniques (such as boot cdrom, etc.).
With that said, this problem will occur if there is no "ses"
entry in the /etc/devlink.tab file.  Check to see if the following
line exists in the file:

type=ddi_pseudo;name=ses       es/ses\N0

If not, add the line to the file.  Then run the commands "drvconfig -i ses" 
and "devfsadm -C".  Now "luxadm probe" should work as expected.
