About cloning virtual machines
VRTSsfmh package generates a globally unique identifier for the host using parameters such as host id and MAC address of the host. Veritas InfoScale Operations Manager Management Server identifies a managed host using this identifier.
Some virtualization technologies such as VMware create a new BIOS UUID for a Virtual Machine when it is cloned. The Veritas InfoScale Operations Manager Agent (VRTSsfmh package) uses this UUID to know if the host has been cloned.
On other virtualization technologies, you need to reset the host id of the clone is reset. If host id is not reset, both the clone and the cloned hosts are recognized as the same, which can cause data corruption in the Veritas InfoScale Operations Manager database. After you reset the host id of the clone, Veritas InfoScale Operations Manager removes any managed host-related configuration from the clone that gets copied over from the cloned host. The clone is treated as a new host and has to be added as a managed host to the Management Server domain.
