1. Install a valid version of VMware Tools on all VM hosts that will be discovered/monitored by the vmware probe.
2. Clear the niscache directory on the robot where the vmware probe is installed. This can be done using the controller probe utility as follows:
From Infrastructure Manager:
a. Select the controller probe on the robot where the vmware probe is installed and enter <ctrl>p
b. Select the Options button (button with the yellow gear) and select the "Expert Mode (no confirmation required)" on the Options GUI
c. Select OK to save the change
d. From the Probe commandset drop down list, select the _nis_cache_clean command
e. Select the green arrow (play) button to execute the command
From Admin Console:
a. Left-click the drop down list for the controller probe on the robot where the vmware probe is installed and select Probe Utility
b. Select the _nis_cache_clean command from the command list
c. Select the green arrow (play) button to execute the command
3. If only a few devices have duplicate entries in the CM_COMPUTER_SYSTEM table, you can delete both entries for each device from the CM_COMPUTER_SYSTEM table using the remove_master_devices_by_cskeys callback in the discovery_server probe utility. If there are a large number of devices with duplicate entries, then do a full discovery reset.
