The scenario is an example of initiating an auto discovery. Navigate to the Device Details page for a
newly discovered device and shutdown an interface. Assume the Home page as the starting point for this
exercise. This is a high level overview of the process and does not contain specific, packet for packet,
request/response pairs.
To initiate an auto discovery:
1. From the IMC home page, click the Resource tab located at the top of the Home page.
The following workflow applies:
a. The common SPL publishes the request for the Resource page to the communication bus.
b. The Resource CSU picks up the request and invokes the DAL for the data that is used to render
the dynamic data (device status) that is displayed on the Resource home page.
c. The DAL publishes a call to the database for current information on the status of devices in IMC
and the database picks up the request.
d. The results of the database query for current information are stored in the Data Cache.
e. The Resource CSU picks up the results of the database query and publishes the Home page
response with the dynamic data to the communication bus.
f. The common SPL picks up the Home page response and renders it on the operator's local
computer.
2. Click the Auto Discovery link to begin the process of automatically discovering and adding devices
to IMC.
The following workflow applies:
a. The common SPL publishes the request for auto discovery on the communication bus, which is
picked up by the Service Logic Layer.
