The following table describes the PPRC CESTPAIR command parameters for creating pairs.

Parameter	Value	Description
DEVN	Device number	NA
PRIM	Primary volume: SSID, serial number, channel connection address, and CU number	To request the Split directly, specify MSF00 instead of a serial number. Note: This parameter is valid for MODE(COPY) or MODE(NOCOPY) only. To assign a pair to a CTG, specify MA`nn`0 instead of a serial number, where `nn` is a CTG ID. You must use these parameters to successfully run the command.
SEC	Secondary volume: SSID, serial number, channel connection address, and CU number	NA
MODE	COPY	The storage system recognizes only COPY for the MODE parameter, even if NOCOPY is specified.
MODE	NOCOPY²
PACE	Any number	Copy speed is medium, regardless what you specify for the PACE parameter.
CRIT	Not applicable	Not used by SIz.
MSGREQ	YES²	MSGREQ function is applicable. Note: Do not specify YES for this parameter when you request the Split directly. If you specify YES for this parameter, the command is rejected and ends abnormally (reporting CC = 8).
MSGREQ	NO	MSGREQ function is not applicable.
ONLINSEC¹	YES	The pair is created whether the S-VOL is online or not.
ONLINSEC¹	NO	If the S-VOL is online, the pair is not created.
1. Not specifying and specifying NO for this parameter have the same affect. 2. If you specify NOCOPY as the MODE parameter and YES as the MSGREQ parameter, the CESTPAIR PPRC command ends before the copy operation is completed.

The following is an example of using the CESTPAIR command to create pairs:

 
CESTPAIR DEVN(X'3E00')
PRIM(X'00C6',00002,X'00',X'C6') -
SEC(X'00C6',00002,X'01',X'C6') 
MODE(COPY)
