Here is my situation:

Specify disk (enter its number):


Under new EMC driver for HBA, new SAN drive is using "emcpower0a", while it 
also has an another entry under output of format, like item 0, 1. It also 
point to emcpower0a.

The problem is if I list the link file for two local drivers (item 2,3), it 
acutally points to item 0, 1, which is incorrect.

How did this happen and how do I fix this?

You're using PowerPath which combines all SAN paths to one disk into one.

You can safely use the /dev/[r]dsk/emcpower devices and disregard the rest.
