Ontap 8.3.5 MetroCluster/AIX Hosts

Anyone had success configuring AIX hosts MPIO settings in a metrocluster environment.

Using NetApp Host Utilities 6.0

NPIV VIO clients used for testing.  AIX Version 7.1.3

Experiencing IO delays/hang for approximately 50 seconds during switch over and switch back.

Assuming this is a disk rw_timeout issue after looking at nsanity logs from the host.

Not aware of any way to reduce the 30 second read/write on the LUN.
