Is this possible with SAS? How and where would I specify this?

The specific disk I am testing this move with shows up in prtpicl as:
-pci8086,25f8 (pciex, cd00000307)
--pci8086,32c (pci, cd0000032f)
---pci1028,1f04 (obp-device, cd00000354)
----sd (block, cd000008fd)
In prtconf it shows up as:
sd, instance #42
Is there another, better way I should be trying to do this?
Hi Don,
we don't have this with SAS. At least, while it might be
coming in future (I don't know), it's not there today. Also,
with your LSI SAS1068E controller, the chip keeps track of
up to 122 separate WWNs and provides the OS with a logical
target id. This does get in the way of keeping a consistent
mapping going on, sorry.
The good news is, however, that FMA provides you with copious
details that help you over the problem:
