1012001 ITAC Server Abnormal

Description

After startup, the ITAC sends a heartbeat message to the IT adapter (ITA) every 2 minutes. The heartbeat message contains memory usage. This alarm is generated when the ITA does not receive the ITAC heartbeat message for three consecutive times. This alarm is cleared when the ITA receives the ITAC heartbeat message again.

Parameters

Name

Meaning

Alarm ID

Identifies an alarm. Each alarm is uniquely identified by an alarm ID and an alarm name.

Alarm Severity

Indicates the severity of an alarm. Value:

  • Critical: indicates that a fault affecting services provided by the system occurs. You need to rectify the fault immediately. If a device or resource is faulty, rectify it immediately even if the fault occurs during non-working hours.
  • Major: indicates that a fault affecting the service quality of the system occurs. You need to rectify the fault immediately. If the service quality of a device or resource is degraded, rectify it immediately during working hours.
  • Minor: indicates a fault that does not affect service quality. To prevent more serious faults, this type of alarm needs to be observed or handled if necessary.
  • Warning: indicates a fault that may affect service quality. This type of alarm must be handled based on the error type.

Alarm Name

Identifies an alarm. Each alarm is uniquely identified by an alarm ID and an alarm name.

Object Type

Specifies the type of the object for which the alarm is generated.

Alarm Object Name

Specifies the name of the object for which the alarm is generated.

Component Type

(This parameter exists only in FusionManager.)

Specifies the name of the component for which the alarm is generated.

Generation Time

Specifies the time when the alarm is generated.

Clear Time

Specifies the time when the alarm is cleared.

Clear Mode

Specifies whether the alarm is manually or automatically cleared.

Operation

Specifies the operation that can be performed on the alarm.

Value: Manually Clear Alarm

Impact on the System

The ITAC server is not available and the administrator cannot manage virtual machines (VMs).

Possible Causes

  • IP addresses conflict.
  • The IP address has been changed. The alarms generated by the IP address must be manually cleared and the alarm component information must be reconfigured.
  • The network is faulty.
  • The ITA server is not running properly.

Procedure

  1. Log in to the server where the alarm is generated using an administrator account and run the arping -c 3 -f -D -I eth0 IP address of the server where the alarm is generated command to check whether IP conflict occurs.

    • If yes, go to Step 2.
    • If no, go to Step 4.

      If the information similar to the following is displayed, no IP conflict occurs:

      ARPING 192.168.162.11 from 0.0.0.0 eth0 
      Sent 3 probes (3 broadcast(s)) 
      Received 0 response(s) 
      (Note: The IP addresses are only examples. Use the actual IP addresses.)     

      If the information similar to the following is displayed, IP conflict occurs:

      ARPING 192.168.162.11 from 0.0.0.0 eth0 
      Unicast reply from 192.168.162.11 [12:6E:D4:AB:CD:EF]  1.022ms 
      Sent 1 probes (1 broadcast(s)) 
      Received 1 response(s) 
      (Note: The preceding IP addresses and MAC addresses are only examples. Use the actual IP addresses and MAC addresses.)     

  2. Log in to the server that causes the IP conflict, shut down the server or change the server IP address, and run the arping -c 3 -f -D -I eth0 IP address of the server where the alarm is generated command again on the server where the alarm is generated to check whether the IP conflict persists.

    • If yes, contact Huawei technical support.
    • If no, go to Step 3.

  3. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 4.
    • If no, no further operation is required.

  4. Log in to the ITAC server that runs properly as user gandalf. Run ping -c 3 IP address of the ITAC server on the CLI to check whether the network is normal.

    • If yes, go to Step 7.
    • If no, go to Step 5.

      The communication is normal if the command output is as follows:

      PING 192.168.190.2 (192.168.190.2) 56(84) bytes of data. 
      64 bytes from 192.168.190.2: icmp_seq=1 ttl=64 time=0.047 ms 
      64 bytes from 192.168.190.2: icmp_seq=2 ttl=64 time=0.057 ms 
      64 bytes from 192.168.190.2: icmp_seq=3 ttl=64 time=0.058 ms 
      (Note: The IP addresses are only examples. Use the actual IP addresses.)     

  5. Locate and rectify the network fault based on the actual situation on site.
  6. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 7.
    • If no, no further operation is required.

  7. Enter the FusionAccess network address in the address box of the browser, and press Enter.

    The address format is http://service IP address of the ITAC server:8081/portal. For example, enter http://192.168.1.10:8081/portal.

    The FusionAccess login page is displayed.

  8. Enter Username and Password and Domain.
  9. Click Login.
  10. Check whether FusionAccess can be logged in properly.

  11. On FusionCompute, choose Resource Pools > VM, locate row that contains the target ITAC server, and choose More > Power > Restart in the Operation column to restart the ITAC server.
  12. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 9.
    • If no, no further operation is required.

  13. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, contact Huawei technical support.
    • If no, no further operation is required.
