typedef enum _SCSI_UC_DEVICE_USAGE_TYPE {
  ScsiDeviceUsageTypeUndefined,
  ScsiDeviceUsageTypePaging,
  ScsiDeviceUsageTypeHibernation,
  ScsiDeviceUsageTypeDumpFile,
  ScsiDeviceUsageTypeBoot,
  ScsiDeviceUsageTypeInlineCryptoEngine
} SCSI_UC_DEVICE_USAGE_TYPE;

ScsiDeviceUsageTypePaging The page file will be used on the device.
ScsiDeviceUsageTypeHibernation The hibernation file will be used on the device.
ScsiDeviceUsageTypeDumpFile The dump file will be used on the device.
ScsiDeviceUsageTypeBoot The device is used to boot the operating system.
