Previously a device was deleted from USM in an attempt to resolve metric discovery issues.
This device was deleted with the option "Prevent rediscovery" checked.
Need to rediscover and redeploy a robot back to this device.
When performing a rediscovery now, the device does not appear in the USM portlet in UMP
In UIM 8.5.1 there is option to remove a device through USM.
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.
Note that incoming inventory data for devices 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"
