MPIO-DSM Active/Non optimized

kala — Wed, 04 Jun 2025 18:14:30 GMT

Hi,

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".

Regards.

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.

Hi,

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.
