DescriptionValueParameter
Device number.DEVN
If you set a parameter other than the
parameters on the left, the command will be
rejected.
Primary volume (S-VOL): SSID, serial number,
channel connection address, and CU number.
1
You must set MSF00 instead of a serial number
to request the Add and Split operation. This
PRIM
parameter is valid for MODE(COPY) or
MODE(NOCOPY) only.
You must set MAnn0 instead of a serial number
if you create SIz pairs in a CTG with ID nn.
Secondary volume (T-VOL): SSID, serial
number, channel connection address, and CU
number.

SEC
When you perform CESTPAIR command on
SIz, no matter whether you specify COPY or
COPYMODE
NOCOPY
NOCOPY for the MODE parameter, the
storage system recognizes it as COPY mode.
Therefore, initial full-volume copy will be
performed.
Copy speed will be slow, except when the DKC
emulation type is 2105 or 2107. When the
1PACE
DKC emulation type is 2105 or 2107, the
copy speed is always medium regardless what
you specify for the PACE parameter.
Copy speed will be medium.other than 1
SIz does not use this parameter. SIz ignores it.Not applicable.CRIT
MSGREQ function is applicable.YESMSGREQ
Note that you cannot use the MSGREQ function
when the Add and Split operation is required.
If you specify YES for this parameter when the
Add and Split operation is required, the
command will be rejected and end abnormally
by reporting CC = 8.
MSGREQ function is not applicable.NO
Pair create operation will be performed
whether the T-VOL is online or not.
YESONLINSEC
2, 3
Pair create operation will not be performed if
the T-VOL is online.
NO
1
CU number is valid only for the DKC emulation type 2105 or 2107.
2
When you do not specify the parameter, the result is same as when you specify NO for this parameter.
3
The ONLINSEC parameter is valid only for the DKC emulation type 2105 or 2107.
If you specify NOCOPY for the MODE parameter and YES for the MSGREQ parameter, the
CESTPAIR command will end before the copying operation is completed.
Figure 40 (page 93) shows an example of the CESTPAIR command.
