## Data Object Description

The VirtualSCSIController data object type represents a SCSI controller in a virtual machine.

Properties

Name | Type | Description
--- | --- | ---
hotAddRemove* | xsd:boolean | All SCSI controllers support hot adding and removing of devices. This support can't be toggled in the current implementation. Therefore, this option is ignored when reconfiguring a SCSI controller and is always set to "true" when reading an existing configuration.
scsiCtlrUnitNumber* | xsd:int | The unit number of the SCSI controller. The SCSI controller sits on its own bus, so this field defines which slot the controller is using.
sharedBus | VirtualSCSISharing | Mode for sharing the SCSI bus. The modes are physicalSharing, virtualSharing, and noSharing. See the Sharing data object type for an explanation of these modes.
