Hello,
When Spectrum put a devices on Initial state, many of the times its because the devices its not reachable and not anwering (ping or snmp) after the creation just for 1 time, so Spectrum doesnt know if the devices still there.
Check that you can send a ping to the device and poll them manually. If they can response ping an SNMP, you can use the attibutes folder ( on Component Detail panel) and select Model_State attributte and change it from Initial to Active(6). If this fix the problem you can change the same attribute to all the devices in your VNM.
Regards
Jose
