Figure 44 Copy pair status transition with Cnt Ac-S Z, TCA, or Cnt Ac-J Z
When the Delta Resync function is used, transitions might occur for copy pair statuses other than
shown in
Figure 44 (page 87) . For details about Continuous Access Journal Z copy pair status
transitions for the Delta Resync function, see “Copy pair status transitions for Delta Resync pairs”

Status monitoring for copy groups
The YKEWAIT or YKWATCH command enables you to monitor a copy group status by copy pair
or volume. For details about the differences in the functionality between the YKEWAIT command
and the YKWATCH command, see
“Functions that monitor events and errors” (page 116) .
Status monitoring by copy pair
The YKEWAIT command can be used to monitor copy group statuses. When this command is
executed, processing halts until the status of all copy pairs in the copy group matches that specified
by the GOTO parameter.
The YKEWAIT command can also be executed with the GOTO(DUPLEX) parameter specified for
a copy group container with EXCTG ID specified, so that all journal groups within the copy group
container are monitored until they are registered with EXCTG.
