It looks like there is a SAS expander attached to the LSI,2308_2?

When a disk is directly attached to a LSA,2308 the canonical name shows up in 
the wwn format, like this:

{0} ok " 9,0" decode-unit encode-unit type
w5000cca01642183d,0

But it looks like it shows up in the target,lun format when attached thru an 
expander.

Could you try out this change:
