Summary :
VMWare virtual machine Device records are duplicated for no apparent reason. The origonal device record transitions to offline, and the virtual machine assumes the identity of the new device record.

In modern, 9.0+, versions of HPSA, if the UUID of a managed server changes, we interpret this change to mean that the server being managed was cloned.  We reach to this change by cloning the device record in HPSA and pushing the new mid file and agent crypto to the managed server.

If the UUID change was not a result of a clone of the managed server, then this will result in the old device record going offline, and the managed server assuming the identiy of new device record.

Solution

There are several circumstances whereby a VMWare virtual machine's UUID will change.  Some of these are not the result of a VM clone.  The following VMWare articles describe some of these UUID management issues:
