Description (partial)

Symptom:
Configurations on CX can be restored using the CX CLI and the "system config restore" command. If this action is performed to a CX that has been imported into multi-mode PRSM, PRSM may fail deployments to the CX as it may duplicate the unique identifier (UID) of an existing box.

For example, take two CX imported into PRSM - CX-A and CX-B.

Assume CX-B becomes corrupted and needs the configuration rebuilt. If the config from CX-A is exported and then imported into CX-B, then CX-B will have the same UID as CX-A. Under this condition, deployments to CX-A may fail.

Conditions:
This only occurs when there are two unique CX (non-failover) imported into CX and a database restore is performed without reimporting the CX.
