3.4.13.1 Page code and allocation length
The Mode Sense command descriptor block contains a page code
(byte 2, bits 5–0) and an allocation length (byte 4). These parameters
are described in the following table for SCSI-2 devices. You can transfer
mode pages to the initiator either of two ways:
Transfer all mode pages at once by using page code 3F
Transfer one mode page at a time by using the page codes and any
number greater than or equal to the allocation length of the mode
page.
