Hello,

I have an issue when trying to delete un-instrumented devices from the device tree.  They seem to delete fine via the GUI, but when the next discovery cycle runs, they are re-added to the Unknown list, even if the device itself is off and no longer pinging back. 

I guess at some point, someone had turned off the Instrumented Devices check box and had a scan run, and that's why I'm seeing them.  But as of now, the Instrumented Devices is checked and I can't seem to delete these items.  

I've read some posts on having to delete the range from DiscoveryConfiguration table in MSSQL, but I would rather not have to recreate all my ranges again.  

Unfortunately, I have over 2000 devices in the unknown tree and it's almost impossible to see if the device is non-Dell, or if I have an OMSA or SNMP issue.  

On the latest 2.1 version.
