Table 5-19. VPD Page Format Field Description

BYTE	BIT	VALUE	DESCRIPTION
0	0-4		The meaning of the Peripheral Qualifier and Peripheral Device Type fields depend
	5-7		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.
1	0-7		The Page Code field identifies the format and parameters defined for that VPD page.
3	0-7		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 initiator 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 trun-
			cation.
4-n			The VPD parameters for each page are described in the following sections.

** NOTE **

All Inquiry ASCII data generated in fields representing numerical val- ues (e.g. power-on time, cleaning count, etc.) is the ASCII equivalent to the hexadecimal numerical value.
