If I understand you are asking, the answer is nondisruptive removing shelves (and not just replacement of a shelf module) from an existing loop is not supported, i.e., you will have to shutdown your storage controller(s) and then replace the shelf.

Interesting. Is this something NetApp are planning to support in the future. Is there a document on NOW that covers this that I should be reading?

Also this brings me to ask (I think I already know the answer) can you add a shelf to a loop without taking the storage controller down?

Thanks everyone for the helpful answers on this, we are now scheduling in the downtime.

Kind regards.
