Symptoms
Sun StorEdge[TM] A5000:Symptom:luxadm Probe Returns Disk Drive Data Paths Instead of A5x00 Enclosure Information.

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
Logical Path:/dev/rdsk/c1t0d0s2
Logical Path:/dev/rdsk/c12t0d0s2
Node WWN:20000020370f44f0   Device Type:Disk device
Logical Path:/dev/rdsk/c1t1d0s2
Logical Path:/dev/rdsk/c12t1d0s2
Node WWN:20000020370f46f2   Device Type:Disk device
Logical Path:/dev/rdsk/c1t2d0s2
Logical Path:/dev/rdsk/c12t2d0s2

Resolution
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.
