I've been playing with Space 15.2R2.4 and try to discover 8 devices.
All device is vmx running 17.2R1 and 14.1R4.9.
I can see 5 devices and missing 3 devices.
When I discovered those 3 devices, its said succed and "device is already managed".
But I cannot see it on Devices > Device Management.
Space able to connect ssh directly to those 3 missing device.
Here is sample of screenshot of 1 node discovery. "Device is already managed" but no hostname.
Any clue how to troubleshoot it ?
Found the problem and fix it.
This issue caused by duplicated vmx serial number.
