We have a fairly large deployment of Sun servers in our network that we've recently added to Orion. It seems whenever the server guys reboot their system, the interface name changes on their server, which then makes the old interface in Solarwinds show as down or unknown. I have to go in and delete the old interface, then list all resources on the server and add the new interface name. Is there a way to automate this ... either from the server end or from Solarwinds?
Have you tried to re-discover the interfaces via the web node management console?
