ESTPAIR (Adding Pairs)
lists and describes the ESTPAIR command parameters that can be used when
you create SIz pairs.
Table 38 ESTPAIR Command Parameters (Adding Pairs)
Description
Value
Parameter
You should specify only one parameter of the
three parameters. The italic part on the left
DDNAME = dname = JCL statement identifying
the volume.
DDNAME,
SYSNAME, or
UNITADDRESS
means that it is the arbitrary name. For
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
example, dname means the arbitrary unique
name of the JCL statement which identifies the
volume.
UNITADDRESS = ccuu = device number.
If you set a parameter other than the
parameters on the left, the command will be
rejected.
Primary volume (S-VOL): SSID, serial number,
and channel connection address.
You must set MSF00 instead of a serial number
to request the Add and Split operation. This
PRI
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, and channel connection address.
SEC
When you perform ESTPAIR command on SIz,
no matter whether you specify COPY or
COPY
MODE
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
1
PACE
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
If you specify this parameter when
MODE(RESYNC) is set, the command ends
YES
MSGREQ
NO
abnormally by reporting CC = 12. Do not
specify this parameter when MODE(RESYNC)
is set.
Primary volume CU number, or secondary
volume CU number.
1
LSS
Pair create operation will be performed
whether the T-VOL is online or not.
YES
ONLINSEC
2
Pair create operation will not be performed if
the T-VOL is online.
NO
1
CU number or the parameter 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.
