I guess you need a MPIO. Multipath software presents the operating system with a single virtual device that represents the active multiple physical paths to the storage.

I am not sure what the commands are for AIX, but try this and check if NetApp AIX MPIO is installed?

# lsdev -Ccdisk

I don’t know which AIX OS you got, but some references: (Just look up)
