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
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
