The tip applies to UIM 8.5.1.


In UIM 8.5.1 you are able to remove a device through USM.

Let me describe a caution in the feature.


If a device is removed through USM with “Prevent rediscovery” option enabled,

the device is placed in black-list, which discovery_server uses the below CSV file to maintain the list.




Keep in mind that coming inventory data listed in the black-list, will no longer be saved into UIM database.

If a device is accidentially placed in the list, here is steps to dettach.


1. Deactivate discovery_server probe

2. Remove device from the list

3. Activate discovery_server probe


If you want to remove the whole list, run discovery_server callback "clear_all_prevented_devices"


For more information, please take a look at the below docops page.
