# SCSIParallelFeature

A feature that the driver extension supports.

## Declaration

```occ
typedef enum SCSIParallelFeature : unsigned int { ... } SCSIParallelFeature;
```

## Overview

Overview This enumeration defines feature selectors the framework uses to identify features of the SCSI parallel interface. The UserDoesHBASupportSCSIParallelFeature function uses these to report whether the HBA supports a SCSI parallel interface feature. The framework also uses these to request negotiation and report negotiation results between the controller and the device.
