YES
Make a copy pair even if the copy destination volume is online.
NO
Do not make a copy pair if the copy destination volume is online.
NOTE:
• If ONLINE(YES) is specified, volume corruption might occur because a copy pair can be
made even if the S-VOL is being used. Thus, consideration with respect to volume operation
is required, such as limiting operation to periods when the S-VOL is not being used.
• If transition to HOLD status is not performed, this might indicate an environment in which
differentials cannot be maintained in the journal. Check the number of TrueCopy copy pairs
sharing P-VOL with the specified copy pairs, the number of CAJ copy pairs sharing S-VOL
with the specified copy pairs, and the status of copy pairs.
• Because the EXCTG registration processing is performed asynchronously with the YKMAKE
command, an error might occur during EXCTG registration even if the YKMAKE command
terminates normally. Therefore, after executing the YKMAKE command on a CG container
specified by EXCTG ID, execute either the YKEWAIT GOTO(DUPLEX) command or the
YKQUERY command to check if an error occurred during EXCTG registration.
• If the YKMAKE command is executed for a copy group container with an EXCTG ID, EXCTG
registration might fail with error code 3688 even if a copy pair is successfully created. If error
code 3688 occurs when the YKMAKE, YKQUERY, or YKEWAIT command is executed, re-execute
the YKMAKE command specifying SELECT(COND) to register the journal group in the EXCTG.
Return Codes
“Return codes when the YKMAKE command terminates” (page 225) lists the return codes to be
returned when the YKMAKE command terminates.
Table 123 Return codes when the YKMAKE command terminates
MeaningReturn Code
The command terminated abnormally, possibly because the user SVC routine has
not been included properly.
-4095 to -4040
The module cannot be loaded. Possible causes are as follows:-3
• The library dataset has not been linked.
• The module is protected by the RACF program control function.
An interruption occurred during execution.-1
The command completed normally.0
Since a volume with an invalid status was found in the copy group, processing for
the volume will be skipped.
