If the above-mentioned conditions are all fulfilled, and when an error occurs to one of the journal
groups, the error will be communicated to other journal groups. If you use RAID Manager, and if
a journal group is in the normal status, it will be shown as PJNN. When an error occurs, the status
of the journal group changes from normal to PJSE. In case of the capacity overflowing, the status
changes to PJSF. When one journal group becomes PJSE or PJSF status, all other normal journal
groups in PJNN status also become PJSE status (suspended by error). Note that, although some of
the pairs in the journal group become suspended by an error, if the whole journal group does not
become suspended, the status of other journal groups will not change.
