A virtual machine with this name was backed up, and it has a different virtual machine UUID than the virtual machine that is backed up now. This can occur if there are two virtual machines with the same name that are backed up to the same TSM data center node name. In this case, the backup can not continue because the backup-archive client uses the virtual machine name to uniquely reference the virtual machine on the TSM server.
The backup of this virtual machine fails. The backup process can continue with other virtual machines.
If the VM's UUID changed, run a BACKUP VM command with VMBACKUPUPDATEGUID option. The VMBACKUPUPDATEGUID option updates the UUID on the TSM server.
