Decommissioned (Missed) Devices refer to the devices that are in the current domain but cannot be found in the last discovery. After the discovery, you can check whether there are any decommissioned devices in the Fine Tune.
To resolve decommissioned devices, complete the following steps:
2.In the Domain Management page, click Fine Tune on the Start Page or select Operations > Fine Tune from the quick access toolbar.
4.Select the devices, right-click them, and select Discover Selected Device(s).
5.On the Discover tab, rediscover the decommissioned devices to verify whether they can be discovered.
1)Select Scan IP Range to only discover the specified IPs.
3)Click Network Settings to specify the proxies and credentials to be used in the discovery or keep it as default.
4)Click Start Discovery.
If these devices are rediscovered successfully, they can be automatically moved from the Missed Devices category to the Discovered Devices category. Otherwise, you can manually remove them from your domain by right-clicking them and selecting Remove from Domain from the drop-down menu.
