The Native Rest API is a new feature that is meant to replace mm-commands in the long-term. The Native Rest API feature is being delivered in phases. For the 5.2.2.0 GA, not all the functionality that mm-commands expose will be available in the Native Rest API. Due to this limitation, all mm-commands will remain available, and complete co-existence is supported by the Native Rest API with mm-commands (meaning you can run both at the same time).
The Native Rest API will not require GUI administration. With the Native Rest API, there is a new CLI that has a similar look to its equivalent mm-command (-N options, -F options with stanza files, and many of the same flags per command, just a different invocation).

The Native Rest API will not require installing the GUI. It does require a new RPM+service, but it does not expose a GUI itself. Once the Native Rest API exposes the functionality that the GUI requires, the GUI itself will rely on the Native Rest API (assuming you want a GUI running), as well as other internal components that today rely on mm-commands.
Thanks,

I just had an email from IBM about technology preview of the "Native
Rest API" feature in 5.2.1.0
There are at least two interrelated and important questions that are not
answered in the web page about this "Native Rest API" feature IMHO.
Firstly the page says it "eliminates" the need to administer the Scale
cluster with the mm-command layer. Does that mean the mm-command layer
is going away? Will I in the future going to forced to use some "naff"
GUI layer to administer a GPFS cluster? Frankly I am quite happy using
the mm-command layer thank you very much and would like to keep it that
way and just be able to ignore the GUI. I do appreciate I might be
somewhat old school in that view but never the less I view GUI
administration of things with disdain.
Secondly at the moment the Rest API requires installing the GUI. Does
the "native" bit of the title mean that requirement is going away and
there will be a Rest API without the need for the additional complexity
of the GUI nodes? Or is the mm-command layer going away and yes you will
need the extra complexity of the GUI because you are going to have to
suck up administering the system with a GUI?
JAB.
