Does the '-M' option to mmlsdisk provide the information you're
looking for? i.e. from the man page:

Displays whether I/O requests to the disk are satisfied on the local
node, or using an NSD server. If the I/O is done using an NSD  server,
 shows  the  NSD server name and the underlying disk name on that
server node.

It should display something similar to the following:

Disk name     IO performed on node     Device             Availability
------------  -----------------------  -----------------  ------------
nsd1          localhost                /dev/disk1       up
nsd2          node01.example.com       /dev/disk2       up
nsd3          localhost                /dev/disk3       up
