Identification Descriptor

The device Identification Descriptor is returned by both the Parallel SCSI- and

Fibre-Channel-attached devices.

The Code Set field is 2, indicating the Identification Descriptor contains only ASCII

data.

This device supports Identifier Type of 1. In this case, the Identification Descriptor is

the Vendor ID followed by the Product Identification field from the standard inquiry

data and the Serial Number field from the Serial Number Inquiry Page (see “Unit

Serial Number Page” on page 10).

The Parallel SCSI drive reports only the single Identification descriptor of Identifier

Type 1.
