The following warning message was found in the "server.log" file on an HP Diagnostics Mediator server:
License has expired!
If an independent (non Commander mode) Diagnostics Mediator server has a license installed, the license validation check will take the following action:
for a Permanent License: after the "Instant-on" license expires (30 days) , the Mediator server will show license WARNINGs for invalid license even though no license is required for a Mediator,
for an Instant-on License: see WARNING: Instant-on license will expire.
As the Mediator is not in Commander mode, it does not require any license. Remove any license files and restart the Mediator.
