Command Specifications
l.
Data strobe offset count (not supported)
This field specifies in two's-complement notation an incremental position to
where the recovered data strobe is adjusted from its nominal setting. Any
value specified in this field does not preclude the device server from using
positive or negative data strobe offset during error recovery. However, after
any error recovery is completed the device server returns the data strobe offset
to the value specified in this field.
The IDD is not supported this field. Therefore, the IDD ignores the specified
value in this field.
m. Number of retries during write
This field specifies the maximum number of times writing of data to the disk
media is retried in the case that there has been an interruption in a write
operation such as a shock. The number of retries specified in this field is
applied to each logical block unit. When zero is specified in this field,
retrying of writing to the disk is prohibited.
The value specified in this field is applicable to the WRITE command,
WRITE EXTENDED command, write operation in the WRITE AND
VERIFY command and write test in the SEND DIAGNOSTIC command.
When the page length in Page 1 is specified as X '06,' the value specified in
this field is not transferred from the INIT, but in this case, the value specified
in the "Number of retries during READ," on the same page, is also applied to
this field by the IDD.
n.
Recovery time limit (not supported)
This parameter specifies the maximum time that can be used by the TARG
for error recovery processing, as a 1ms constant. The value specified in this
parameter is the maximum permissible time for error recovery processing for
each individual command. When both this parameter and the "Number of
retries" parameter are specified, the parameter which specifies the shortest
time must be given priority in application.
If less than 5000ms is specified, the IDD performs rounding processing and
sets 5000ms.
