Figure 4.1 Mode Select Parameter Structure - Fujitsu MAU3147RC SERIES Technical Manual

The IDD has a common set of "Current", "Save" and "Default" values of all the
MODE SELECT parameters for all the INITs.
When the IDD's power is switched on, when HARD RESET is received,
LOGICAL UNIT RESET TASK is received, the "Current" MODE SELECT
parameter values are changed to the "Save" parameter values, if they exist, and are
changed to the "Default" parameter values if the "Save" values do not exist.
When any of the variable parameters of this command are changed, the unit
attention condition is generated for (Mode parameters changed [= 2A-01]) for all
the INITs except the one that has issued this command.
Figure 4.1 shows the relation between the three types of parameters, "Current,"
"Save" and "Default".

Remark
When the drive is shipped from the factory,
there are not parameter page "Save" values
except for Page 3 (Format Parameters) and
Page 4 (Drive Parameters). "Save" values for
the parameter pages specified in the MODE
SELECT command are generated for the first
time when that command is executed with "1"
specified in the "SP" bit.
