check that the Node Agent is running.

In the WAS 8.5 world, the remote management of IHS is undertaken by the Node Agent, rather than the IHS Admin Server Instance ( adminctl etc. ).

This, of course, assumes that WAS and IHS are tightly coupled, which may go against the suggested WAS security hardening routines such as: -



Bottom line, check your non-functional requirements, including security, when deciding whether IHS/Plugin should be tightly wired to the WAS cell / Deployment Manager.
