Hello everyone,

I have couple of basic questions on Powerpath installation and operation on AIX

1) Are there any extra benefits of using Powerpath for rootvg instead of MPIO ? What does PowerPath offer that MPIO doesn't ?

2) If we implement PowerPath later after rootvg has been using NPIV under MPIO control, are there any issues ?

We had a LPAR booting off EMC using NPIV under MPIO, then boot device has 4 paths configured from VMAX array. And then Powerpath and ODM sets were installed on LPAR; boot and data devices are brought under Powerpath control. This way is not in the install guide, not sure if there are any concerns doing this. 

Thanks , I appreciate any feedback.
