may generate unpredictable results on the source and target virtual
machines.
Storage Mirroring Recover for Virtual Infrastructure supports generic SCSI
device mappings in virtual machines, however, the generic SCSCI device
will not be created on the target virtual machine during failover because the
target virtual machine will fail to start if the SCSI device hardware does not
exist on the target ESX host. After failback, the generic SCSI device will be
mapped back to the original source, but the SCSI device will not be
mapped back to the original source if the protection job is re-created in the
reverse direction.
