The second and third paragraphs say:
	Identifying information shall persist through power cycles (i.e., be
	in non-volatile storage), hard resets, logical unit resets, I_T nexus
	media format operations, and media replacement.
	Table 61 defines the identifying information types.
The first Identifying Information Type entry in that table says:
	Peripheral device identifying information: a value describing
	the peripheral device (e.g., an operating system volume label)
The example is a problem.  Volume labels generally do not survive media
operations and media replacement.
