For the past 2 years I've been accessing LUNs on our FAS3240 from a Solaris Sparc host (Solaris 10 Update 9) using FCP. There are two QLA2340 cards on the Solaris host. Each is cabled to a separate brocade switches, creating 4 paths to the same LUN.
Solaris multipathing was enabled when the Solaris host was created (stmsboot -e)
I created the igroup on the FAS3240 with ALUA enabled.

This all worked creating for lack of a better term, a single virtual path to represent the 4 physical paths on the Solaris system.
Example:
/dev/rdsk/c13t60A98000646762364634634B7847616Cd0s2 -> ../../devices/scsi_vhci/ssd@g60a98000646762364634634b7847616c:c,raw
We recently purchased a FAS2240 with a single PCM for additional space with the optional mezzanine card with dual FC ports. Since it's a single controller when I create an igroup it's without ALUA.
The problem. When I create a LUN on the FAS2240, the Solaris host is showing two separate paths to the same LUN rather than a single path. There are in fact two separate physical paths but I expect multipathing to create a single virtual path.

- two paths to the same LUN ... not what we want

Any suggestions? I've got a call open with EMC(Solaris) and will open one with NetApp Support as well.
Thanks,
