Note that, for CG containers specified by EXCTG ID, the command checks the EXCTG registration
information for all CG containers.
After specifying the copy pair to operate, to view REXX variables (such as SimplexCt) shown in
information for copy pairs that are not operation targets, execute the YKQUERY command or
YKEWAIT command for all copy pairs.
TO({PRIMARY|SECONDARY})
Applies to Continuous Access Synchronous for Mainframe, Continuous Access Synchronous for
Mainframe with the HyperSwap attribute, Continuous Access Asynchronous for Mainframe, and
Continuous Access Journal for Mainframe.
Specify this parameter to monitor copy groups by monitoring the status of either P-VOLs or S-VOLs.
When the TO parameter is specified, the copy group container is not checked for EXCTG registration
information.
PRIMARY
Monitors the status of P-VOL during copy group definition.
SECONDARY
Monitors the status of S-VOL during copy group definition.
VOLUNIT
Usually, information is obtained for each CU, but when this parameter is specified, information is
obtained for each volume.

lists the return codes to be returned when the YKEWAIT command terminates.
Meaning
The command terminated abnormally, possibly because the user SVC routine has
not been included properly.
The module cannot be loaded. Possible causes are as follows:
The library dataset has not been linked.
The module is protected by the RACF program control function.
An interruption occurred during execution.
The command completed normally.
The timeout interval expired before the group status changed to the requested group
status. For CG containers specified by EXCTG ID, a timeout occurred before all
journal groups were registered in EXCTG.
Unexpected transition of group status.
An error occurred when the suspend processing was performed by using the
CAJ ATTIME suspend function.
The status of the CAJ copy pair was invalid when the suspend processing was
performed by using the CAJ ATTIME suspend function.
The suspend processing has started because the timeout period had elapsed
when the CAJ ATTIME suspend function was executed.
I/O errors were encountered.
A change in an I/O configuration definition was detected.
