Invalid virtual failover clients

An invalid virtual failover client (VFC) is no longer managed by a Unitrends appliance and virtual restores are no longer performed for the VFC. To determine whether a VFC is invalid, view its status using the instructions described in Viewing virtual failover client details.

A VFC could become invalid for the following reasons:

You have booted it in Live mode. For details, see Taking a virtual failover client live. Although virtual restores are no longer performed for the VFC, you can set it to go in and out of Live mode.
The configuration of the original client has been changed (for example, a disk has been added or removed). After you change the configuration of the client, the next virtual restore to the VFC for the client fails, the status of the VFC becomes Invalid, and it remains in a Halted state until you delete it from the appliance. It cannot be set to go into Live mode. For details, see Configuration changes have been made to the original client.
Three attempts to perform a virtual restore have failed because the appliance could not communicate with the VFC. After the third attempt, the status of the VFC becomes Invalid, and it remains in a Halted state until you delete it from the appliance. It cannot be set to go into Live mode. For more details, see The Unitrends appliance cannot communicate with the virtual failover client.
