Members

`CodeSet`

Specifies the code set used by a SCSI identification descriptor to identify a logical unit.

`Type`

Contains an enumerator value of type STORAGE_IDENTIFIER_TYPE that indicates the identifier type.

`IdentifierSize`

Specifies the size in bytes of the identifier.

`NextOffset`

Specifies the offset in bytes from the current descriptor to the next descriptor.

`Association`

Contains an enumerator value of type STORAGE_ASSOCIATION_TYPE that indicates whether the descriptor identifies a device or a port.

`Identifier`

Contains the identifier associated with this descriptor.

Remarks

Every device identification page (page code 0x83) of SCSI vital product data contains a series of identification descriptors. The STORAGE_IDENTIFIER structure represents a SCSI identification descriptor.
