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.
