Current Values:
Reports each "Current" parameter value. The "Current" values are either of the
following values.
•
Values specified by a MODE SELECT or MODE SELECT EXTENDED
command which is finally normally terminated.
•
When a MODE SELECT or MODE SELECT EXTENDED command is
not executed after the power is switched on, after a LIP or after a TARGET
RESET issued by any INIT is received, the same values as "Save" values.
However, if "Save" values do not exist for parameters other than those on
Page 3 and Page 4 (excluding byte 17), the same values as "Default" values.
01
Variable Values:
The INIT reports variable parameter fields and parameter bits through the
MODE SELECT or MODE SELECT EXTENDED command. A "1" is
reported in the variable fields and bit positions in each page descriptor and "0"
is reported in the fields and bit positions which cannot be changed. See the
description of each page descriptor for the MODE SELECT command (Section
4.1.4) concerning the variability of each parameter.
10
Default Values:
Reports the "Default" value of each parameter. See the description of each page
descriptor for the MODE SELECT command (Section 4.1.4) concerning the
actual default value of each parameter.
11
Save Values:
Reports the "Save" value of each parameter. The "Save" values are either of the
following values.
•
For parameters other than those on Page 3 and Page 4 (excluding byte 17),
these are the values specified in a MODE SELECT or MODE SELECT
EXTENDED command in which the "SP" bit after the final execution is
completed is "1." When a MODE SELECT or MODE SELECT
EXTENDED command in which the "SP" bit is "1" is not executed (when
"Save" values do not exist), these are the same values as the "Default"
values.
•
The values in the parameters in Page 3 and Page 4 (excluding byte 17) are
the values save to the disk media during execution of the FORMAT UNIT
command.
