Define a way to put many nodes into maintenance at once
I'd like an easy way to put many nodes into maintenance at once, such as a site (in case of a site outage), or a product line (when a line operator indicates that they want to bring down a production line)

While it is possible to put a node into maintenance from PDS it is very limited. Firstly you can only do that node, not multiple nor the site. Secondly you can only do it if the node is online.
I would propose that there is a mPI portal that allows you to manage all the nodes from one central place.
