 I'm really referring to the LU alias. I asked about this in #illumos (on
 freenode). After that discussion, I'm not sure that it's even exposed by
 the target. Is there an obvious place in the VPD (page 0x80, 0x83, ???)
 where it should be exported? If so, maybe this is just an issue for the
 Illumos side.
 

A netapp engineer suggested trying the REPORT IDENTIFYING INFORMATION
command. To do this you can use sg_ident from the sg3_utils.

$ sudo sg_ident -i 127 /dev/sdm
  Information type: 0, Maximum information length: 0 bytes
  Information type: 4, Maximum information length: 256 bytes

The only one it could be is 4, since the LU alias field is 255
characters, I think. But here are both:

$ sudo sg_ident -i 0 /dev/sdm
$ sudo sg_ident -i 4 /dev/sdm
bad field in Report identifying information cdb including unsupported service 
action
