- Log in to the alarm system and query alarm information.
- Run the following command and enter the root password QAZ2wsx@123! to switch to the root user:
su - root
- Use PuTTY to log in to the LVS node and check the status of the current LVS node.
Run the following command:
cat /opt/dms/lvs/jobs/lvs/status_dir/status
Check whether statuses of both nodes are master.
- If they are, go to 4.
- If status of one LVS node is master and that of the other is backup, the network is restored and the alarm is cleared.
- Run the ping command to check whether the two nodes are connected.
- If the communication between the two nodes is abnormal, rectify the fault.
- If the communication is normal but the fault persists, contact technical support.
Alarm Clearing
After the fault is rectified, the system automatically clears the alarm.
