How to allow a machine to be discovered in ACP after a failback to VMware

Challenge 

A machine is not listed in ACP after performing a failback to VMware.

Cause 

By design, a failback machine in VMware is marked with a flag that blocks it from being rediscovered in ACP right after the process has been completed. This helps to keep the dashboard overview clean from unwanted reoccurring entries.

Solution

The flag can be switch off manually by setting its value to 0.

1. Power off the machine
2. Through the VMware console, right-click on the  Settings, access the  Advanced settings, and set the value for  hystax.deny_discover to  0



3. Start the machine for the changes to take effect. 
The failback machine should now be discovered by Acura and listed in ACP under the corresponding customer's Machines Group.
