You can set an additional parameter corresponding to each request instead
of a serial number.
(1) For an Add and Split request (refer to ” Adding and Splitting Pairs ” on
page 56), the parameter is MSF00. This request is valid for MODE(COPY)
only. The parameter locations and descriptions are as follows:
Byte 0-6: Fixed value (xF0*7)
Byte 7: Indication of MRCF. ‘M’ = MRCF Å Distinguishes SI390 from TC390.
Byte 8: Subcode-1. ‘S’ = Split Å Requests simultaneous add and split.
Byte 9: Subcode-2. ‘F’ = Fast Mode Å Requests quick split.
Byte 10-11: Not used (xF0*2)
(2) For a Quick Resync request, the parameter is MRF00. This request is valid
for MODE(RESYNC) only. The parameter locations and descriptions are as
follows:
Byte 0-6: Fixed value (xF0*7)
Byte 7: Indication of MRCF. ‘M’ = MRCF Å Distinguishes SI390 from TC390.
Byte 8: Subcode-1. ‘R’ = Resync Å Distinguishes resync from add.
Byte 9: Subcode-2. ‘F’ = Fast Mode Å Requests quick resync.
Byte 10-11: Not used (xF0*2)
(3) For a Quick Restore request, the parameter is MRQ00. This request is

Byte 9: Subcode-2. ‘Q’ = Quick Mode Å Requests quick restore.
Byte 10-11: Not used (xF0*2)
(4) For a Reverse Resync request, the parameter is MRR00 . This request is
valid for MODE(RESYNC) only. The parameter locations and descriptions are
as follows:
Byte 0-6: Fixed value (xF0*7)
Byte 7: Indication of MRCF. ‘M’ = MRCF Å Distinguishes SI390 from TC390.
Byte 8: Subcode-1. ‘R’ = Resync Å Distinguishes resync from add.
Byte 9: Subcode-2. ‘R’ = Reverse Resync Å Requests reverse resync.
Byte 10-11: Not used (xF0*2)
If you set a parameter other than the above parameters, the command will be
