Parameters

Name

Description

AppName

Indicates the name of the service that reports alarms.

IP Address

Indicates the IP address of the server on which a service reports the alarm.

Impact on System

SNMP alarms depending on the LVS cannot be reported.

Probable Causes

  • A system error or system file damage occurs.
  • Other services on the node where MORCLVSService is deployed are using the keepalived process.
    NOTE:

    The keepalived process is used to switch the active/standby status of the node where LVS is deployed.

Handling Procedure

  1. Check whether the keyword "error" is displayed in the printing information of the /var/log/messages log on the node where MORCLVSService is deployed.

    1. Use PuTTY to log in to the regionAlias-ManageOne-Service01 node using the IP address of the node.

      Default account: sopuser; default password: D4I$awOD7k

    2. Run the following command to switch to the root user:

      sudo su - root

      Default password: Changeme_123

    3. Run the following command and then check whether the keyword error is displayed in the command output:

      cat /var/log/messages | grep "*error*"

      • If yes, contact technical support for assistance.
      • If no, go to 2.

  2. Run the following command to check whether other services on the node are using the keepalived process:

    ps -ef | grep keepalive | grep -v "RCLVSService/lvs_install" | grep -v "grep" | awk '{print $2}'

    If any command output is displayed, other services are using the keepalived process.

    • If yes, contact technical support for assistance to deploy MORCLVSService on another node so that MORCLVSService uses the keepalived process exclusively.
    • If no, contact technical support for assistance and deploy MORCLVSService again.

Alarm Clearance

This alarm will be automatically cleared after the fault is rectified.
