ALM-80003 Threshold of the Veritas Replication Buffer Exceeded (Major)

Description

The eSight queries the status of the Veritas replication buffer every 5 minutes. This alarm is generated when the eSight detects that the data in the Veritas replication buffer reaches 210 MB. This alarm is automatically cleared when the eSight detects that the data in the Veritas replication buffer is less than 90 MB.

Impact on the System

The service data cannot be synchronized from the primary server to the secondary server so the service data is inconsistent between the primary and secondary servers. When the primary server is faulty, a switchover fails and the eSight will be unavailable.

Possible Causes

  • The NMS applications perform a large number of read and write operations on the database in a short time. As a result, the application I/O bursts and lasts a long time.
  • The data communication network (DCN) is unstable with problems such as high packet loss rate and long delay.
  • The data replication bandwidth is insufficient.

Procedure

  1. Contact related personnel to analyze the possible causes one by one.

    • Contact the NMS administrator to analyze and check the application I/O and the data replication buffer.
    • Contact the device maintenance personnel to check the network bandwidth usage and network quality.

  2. Contact related personnel to solve the problems based on the analysis results.

    • Contact technical support engineers to solve the faults on the application I/O and data replication buffer.
    • Contact the device maintenance personnel to solve the network bandwidth and network quality issues.

  3. After the faults are rectified, Wait five minutes. In the current alarm list, check whether the alarm is cleared.

    • If yes, the alarm handling process is complete.
    • If no, go to Step 4.

  4. Collect the information about alarm handling, and contact the technical support personnel.

Clearing

When the fault is eliminated, the system will auto-clear the alarm. Manual clearing is not required.
