Hello, everyone!
Today, I'd like to share a case with you about how to solve intermittent Abnormal Replication alarms in NCE.
Problem Description
When the disaster recovery (DR) system detects that the data synchronization status between the primary and secondary sites is abnormal for three consecutive times, this alarm is generated.
Problem Analysis
When data is replicated from the primary NCE to the secondary NCE, the data is archived on the secondary NCE for a short period of time, which takes about tens of seconds. During this period, the synchronization between the primary and secondary NCEs is slow. If it's over 10 seconds more than 3 times, the alarm will report.
Solution Description
1. Log in to the master NCE server as the ossadm user. Go to the /opt/oss/manager/apps/DRMgrService/etc/conf directory.
2. Run the vi alarmSettings.json command to edit the alarmSettings.json file.
3. Find for replicationstatus in the document and change the values to 30 in the following red box:
4. Restart the DRMgrService service.Login NCE management plat (31945), go in NCE-OMP, search the DRM, stop and start this service.
5. Perform the same operations on the standby NCE and wait until the DR replication relationship is normal on the active and standby nodes.
Welcome to leave a message below.
We study together.
Thank you!
