When an error occurs in a pair in a journal, if the entire journal is not suspended by the error, the status of the other journals does not change.Notification of suspension due to an error (multiple primary and secondary systems)
When multiple primary systems and secondary systems are combined, an error in one of the journals affects other journals, and pairs are suspended by the error. A time stamp is issued to all journals, and the error in one of the journals is notified to the other journals as long as data consistency is maintained in the system.
To notify all journals of a failure, the following conditions must be met:
The line between CCI and all primary systems is operating correctly.
The status of the failed journal is PJSE or PJSF.
At least one journal in the CCI consistency group is in normal status.
When all the above conditions are met, an error occurred in a journal is notified to the other journals.
The following explains journal statuses:
Normal journals are displayed as PJNN in CCI.
When an error occurs, the journal status changes from PJNN (normal) to PJSE (suspended by error).
For errors caused by capacity overflow, the status changes to PJSF.
When one journal changes to PJSE or PJSF, all other normal journals in the PJNN status also change to the PJSE status (suspended by error).
When an error occurs in a pair in a journal, if the entire journal is not suspended by the error, the status of the other journals does not change.
