The copy group starts being suspended when the 10:00:05 update journal, which was
created after the Cnt Ac-J Z ATTIME suspend time (10:00:00), is detected.
The 10:00:05 update journal is not reflected into the volume at the secondary site, because
the copy group has already been suspended.

, the specified ATTIME suspend time is 10:00:00, so:
1.
The data in the 09:59:58 update journal is reflected into the volume at the secondary
site, because the ATTIME suspend time (10:00:00) has not been reached yet.
2.
The copy group starts being suspended after 10:00:00, when the no-update journal is
detected.
The 10:00:10 update journal is not reflected into the volume at the secondary site, because
the copy group has already been suspended.
•
When timeout occurs:
As indicated in
, when journals are being reflected into the volume at the
secondary site, if neither an update journal nor a no-update journal is detected due to the
disconnection of the paths or other reasons, copy-group suspension will be executed after the
specified timeout time has elapsed from the ATTIME suspend time.
When journals are being reflected into the volume at the remote site, if the timeout time has
expired for a reason such as timeout time shortage or too many update journals, copy-group
suspension will be executed without waiting for the journal reflection to finish.
