Surprised that one of the most approachable outputs for any customer to use which would enable simple identification/resolution of many of these discussions didn't come up, namely:
cfgadm -al for a reasonable physical mapping in which SAS/SATA drives are relatively easy to map out by ID and of course by association with their distinct physical controller paths. And if you want to relate this view to the underlying physical path to the device, then cfgadm -alv will clarify the physical mapping. Both commands can take <controller>::<target> arguments if you want to restrict the voluminous output somewhat. BTW, you also should be looking to mpathadm show LU <device> to successfully decode the virtual device entries.
