Figure 3.31 SEND DIAGNOSTIC parameters: logical/physical address conversion

The "Address Format Before Conversion" field shows the format of the address information
specified in bytes 6 to 13. The IDD converts that address information to the expression format
specified in the "Address Format After Conversion" field. the following codes can be specified as
the "Address Format."
Code
0 0 0
1 0 0
1 0 1
The description format of the address information specified in bytes 6 to 13 is the same as the
description specification of the D List transferred from the INIT by the FORMAT UNIT command.
For details, see the description of the FORMAT UNIT command (Section 3.3.1). furthermore, when
the logical block address format is specified, it must be described in bytes 6 to 9 and zero must be
specified in the remaining byte positions.
When a logical data block address which does not exist (outside the range of the MODE SELECT
parameter) is specified in the logical block address format, or when an area which cannot be
allocated as User Space on the disk drive (cylinders which physically do not exist) is specified in the
"Byte Distance from the Index" format or the "Physical Sector Address" format, that command is
terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in
parameter list [=26-00]) and address conversion is not executed.
Details of the address conversion algorithm executed when this parameter page is specified and the
data format, etc. of the conversion results reported to the INIT are explained in RECEIVE
DIAGNOSTIC RESULTS command (Section 3.4.2).
