0-7

 

The meaning of the Peripheral Qualifier and Peripheral Device Type fields depend

 

 

 

on whether the VPD page is being sent to the initiator as INQUIRY data or is being

 

 

 

received from the initiator as CHANGE DEFINITION data. When being sent as

 

 

 

INQUIRY data, these fields are the same as those defined in the INQUIRY com-

 

 

 

mand description. When being received as CHANGE DEFINITION data, these

 

 

 

fields are ignored.

The Page Code field identifies the format and parameters defined for that VPD

 

 

 

page.

The Page Length field indicates the length in bytes of the VPD parameters that fol-

 

 

 

low. For VPD pages that are permitted to be sent from an initiator via the

 

 

 

CHANGE DEFINITION command, if the initiator does not set this value to the

 

 

 

value that is returned for that page by the INQUIRY command, the target terminates

 

 

 

the CHANGE DEFINITION command with CHECK CONDITION status. The

 

 

 

sense key is set to ILLEGAL REQUEST and the additional sense code is set to

 

 

 

INVALID FIELD IN PARAMETER LIST. For VPD pages requested by an initia-

 

 

 

tor via the INQUIRY command, if the allocation length in the INQUIRY CDB is

 

 

 

too small to transfer all bytes in the VPD page, the page length is not adjusted to

 

 

 

reflect the truncation.

The VPD parameters for each page are described in the following sections.
