Parameter Value Description
ONLINSEC
*2*
3
YES
Pair create operation will be performed whether the
T-VOL is online or not.
NO Pair create operation will not be performed if the
T-VOL is online.
*Note 1: CU number is valid only for the DKC emulation type 2105 or 2107.
*Note 2: When you do not specify the parameter, the result is same as when
you specify NO for this parameter.
*Note 3: The ONLINSEC parameter is valid only for the DKC emulation type
2105 or 2107.
Note: 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 7-2 shows an example of the CESTPAIR command.

ESTPAIR (Adding Pairs)
Table 7-5 lists and describes the ESTPAIR command parameters that can be
used when you create SIz pairs.
Table 7-5 ESTPAIR Command Parameters (Adding Pairs)
Parameter Value Description
DDNAME,
SYSNAME, or
UNITADDRESS
DDNAME = dname = JCL statement
identifying the volume.
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
UNITADDRESS = ccuu = device number.
You should specify only one parameter of the
three parameters. The italic part on the left
means that it is the arbitrary name. For
example, dname means the arbitrary unique
name of the JCL statement which identifies the
volume.
PRI Primary volume (S-VOL): SSID, serial
number, and channel connection address.
You must set MSF00 instead of a serial
number if you want to request the Add and Split
operation. This parameter is valid for
MODE(COPY) or MODE(NOCOPY) only.
If you set a parameter other than the parameters on
the left, the command will be rejected.
SEC Secondary volume (T-VOL): SSID, serial
number, and channel connection address.
MODE COPY When you perform ESTPAIR command on SIz,
