vSphere Replication fails with the error: Unknown controller type (2030526)


  • Protecting a virtual machine using vSphere Replication and VMware vCenter Site Recovery Manager 5.x fails
  • You see the error:

    Unknown controller type
    com.vmware.vim.binding.vim.vm.device.VirtualSCSIController' fod disk '[datastore]/vmname/diskname.vmdk


The issue occurs when the VMDK descriptor has an entry similar to:

ddb.adapterType = "legacyESX"

The legacy ESX adapter type is not supported after VirtualCenter 2.5 Update 2.


To resolve this issue, change the adapter type.
To change the adapter type:
  1. Power off the virtual machine
  2. SSH into the ESX host. For more information, see Connecting to an ESX host using a SSH client (1019852).
  3. Edit the VMDK descriptor and change ddb.adapterType to something else. For example:

    ddb.adapterType = "lsilogic"

  4. Power on the virtual machine.
