Performance Management is integrated with Spectrum. There are some devices in the Performance Management inventory whose Status is Unknown.
How can we get a list of devices whose status is Unknown?
The devices whose Status value is Unknown are normally showing this due to lack of successful Discovery via the Data Aggregator.
Performance Management was synchronized the device(s) from another Data Source, maybe Spectrum, NFA or ADA. After that for some reason the Discovery of the device(s) failed. The result is the Data Aggregator isn't able to determine a status for the device(s).
When requested enter the password for the database. Releases after r3.7.3 require the new complex password set during installation or upgrade.
If needed modify the file output location as needed if /tmp is not usable.
