Sometimes after trusting a node you may notice that it stays greyed out and never actually starts. This may happen during a fresh installation or when migrating an existing installation to a new machine. You may see a messages like the following:

The reason is that you are trying to reach the Spotfire Server on a correct address, but this address was not listed under the addresses while creating the bootstrap.xml file.

Example:

Your Spotfire Server IP is 10.100.x.x and FQDN is company.global.com. Both are accessible but you only listed company.global.com when creating bootstrap.xml Then while installing Node Manager you specified the IP as server address. When the installation is complete, Node Manager will show up under Untrusted Nodes because it was trying to reach the correct address (IP) and you can trust it, but it will remain greyed out because it is not aware of the address where the Spotfire Server is registered.

How to fix greyed out Node that won't start up after trusting it in Spotfire Server

All

Unless you want to recreate a bootstrap.xml file and list all addresses you can apply one of the two solutions:

Option 1:

1). Run

config list-addresses

on the Spotfire Server machine and note down one of the addresses

2). Reinstall the Node Manager and provide one of the listed addresses from Step 1.


Option 2:

1). Run

config list-addresses

on the Spotfire Server machine and note down one of the addresses.

2). Open the <NM installation/nm/config/nodemanager.properties> file, find 'server.name=' and replace the existing value with one of the addresses listed in the previous step. For example:

server.name=company.global.com

If you had any Web Player and/or Automation Services instances, the second option will keep them intact.

Restart the Node Manager service.
