If the MPIO settings show alert you will need to let NetApp adjust the settings. Right click on the host and click on Set Recommended Values. Only the MPIO settings are necessary, but I leave all the boxes checked, just to get Green lights on all the settings. The Status will now show Pending Reboot. Reboot the vSphere host. After the host is running again Update the status. After the update the MPIO should show normal. If the Status still shows alert, I find that if you wait a couple of hours, it will turn to green. Not sure why there is a delay in the status update. The Multipath settings should now show Round Robin, with two paths active. That’s it. Just do this for every vSphere host that you have and you will have 2 active paths for every LUN. Much better than using defaults or changing the settings for every LUN on every host. Hope that helped Best regards
