MPIO-DSM Active/Non optimized



I've juste installed MPIO (Round Robin) et DSM on my WS2012R2 for an Hyper-V cluster. 


Thanks to these videos : 






But when I check the DSM Management MMC, I don't know why the state is "Active/Non Optimized".

Re: MPIO-DSM Active/Non optimized


Kala -


NetApp uses ALUA to communitcate path status with the host.

Paths to interfaces on the node hosting the LUN are reported as Active/Optimized.

Paths to interfaces on any other node not hosting the LUN are reported as Active/Non-Optimized.


Did you truncate the output ?

Do you have interfaces configured on the node hosting the LUN ?

I hope this response has been helpful to you.

Sorry, I'm late.


What do you mean by "Hosting the lun" ?


My SVM where the lun (ISCSI) is works with 4 interfaces :

This is my ISCSI configuration on Windows :

Do you have an idea ?


Best regards.
