Cause

The VM Direct Engine deployment does not allow a duplicate IP address to be used in the environment. The IP address was not responding to Internet Control Message Protocol (ICMP) pings from the Administrator's desktop but was responding to from the PowerProtect Appliance.

Resolution

Resolve the IP conflicts in the environment or use a different IP address that is not being used in the environment.
