ARB Event ID 9

Last Updated : Jan 05, 2021 |
Alarm level

WRN

Cause

Before an interchange, the standby server is significantly in better condition than the active server requesting the interchange. The active server is probably unable to sustain call processing.

Proposed Solution

Procedure

  1. Compare the condition of both the servers:
    1. From the Server section of the Web interface, select Status Summary.
    2. From the Linux command line, enter server.
  2. Using the output from Step 1, check the status of the individual processes of each server.
  3. Check the status of the individual processes of the active server:
    1. From the Web interface, select View Process Status.
    2. From the Linux command line, enter statapp.

    After checking the status of the individual processes, restore any applications that have problems.

  4. Check if the standby side is reset:
    1. From the Server section of the Web interface, select Status Summary.
    2. From the Linux command line, enter server.
  5. Check the status of the individual processes of the standby server:
    1. From the web interface, select View Process Status.
    2. From the Linux command line, enter statapp.

    After checking the status of the individual processes, restore any applications that have problems.

  6. Check for problems with an Ethernet interface:
    1. From the web interface, select the Execute Ping diagnostic.
    2. From the Linux command line, enter pingall -a.

    Check both sides of each failed link, and make any necessary repairs.

    On the Linux command line, enter ifconfig -a.. Ensure the IP addresses match /etc/opt/ecs/servers.conf and /etc/hosts, and check if all ethernet ports have been assigned IP addresses. Enter /sbin/arp -a to ensure that none of the MAC addresses display the incomplete message.

  7. If the applications and interfaces of the standby server are OK but the problem persists, go to the Avaya Support website at http://support.avaya.com to open a service request.

    After the interchange, the condition of the newly active server must be better than the condition of the standby server. See the SOH values bb and cc. See String pairs of ARB Event #9. The server with the larger bb value is considered to be in better condition. If the value of bb is the same for both the servers, the server with the larger cc value is considered to be in better condition. If the condition of the newly active server is better than the condition of the standby server, troubleshoot the standby server.

    If the condition of the standby server is better than the newly active server:

    1. Manually clear the alarm:

      • From the web interface, select Current Alarms and the appropriate alarm, and click Clear.

      • From the Linux command line, enter almclear -n #id.

    2. If the problem persists, go to the Avaya Support website at http://support.avaya.com to open a service request.
