Parameters

Name

Meaning

Fault Location Info

host: specifies the ID of the host for which the alarm is generated.

Additional Info

  • The first parameter specifies the service name. The value is fixed at FusionPlatform.
  • The second parameter specifies the microservice name. The value is fixed at hostos.
  • The third parameter specifies the ID of the host for which the alarm is generated.
  • The fourth parameter specifies the name of the host for which the alarm is generated.
  • user: The value is fixed at fsp.

Impact on the System

Services running on the VM are affected.

Possible Causes

  • The network between the compute node accommodating the VM for which the alarm is generated and the storage plane is disconnected.
  • The VM image is damaged.
  • The user frequently restarts the VM.

Procedure

  1. Obtain the IP address of the server for which the alarm is generated and the VM name or UUID.
  2. Check whether the network between the compute node accommodating the VM for which the alarm is generated and the storage plane is disconnected.

    • If yes, go to 3.
    • If no, go to 7.

  3. Contact the administrator to restore the network between the compute node and the storage plane.
  4. Wait for 5 minutes, and check whether the alarm is cleared.

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

  5. Log in to the Service OM web client.

    For details, see Logging In to and Logging Out of Service OM.

  6. On Service OM, choose Services > Computing > ECS > Compute Instances.
  7. On the Compute Instances page, locate the row that contains the target VM and choose More > VNC Login to log in to the VM using VNC. Check whether the VM blue screen of death (BSOD) or black screen occurs. If the VM BSOD or black screen occurs, the VM image is damaged.

    • If yes, go to 16.
    • If no, go to 8.

  8. Use PuTTY to log in to the first FusionSphere OpenStack node through the IP address of the External OM plane.

    The default user name is fsp. The default password is Huawei@CLOUD8.

    The system supports both password and public-private key pair for identity authentication. If the public-private key pair is used for login authentication, see detailed operations in Using PuTTY to Log In to a Node in Key Pair Authentication Mode.

    NOTE:
    To obtain the IP address of the External OM plane, search for the required parameter on the Tool-generated IP Parameters sheet of the xxx_export_all.xlsm file exported from HUAWEI CLOUD Stack Deploy during software installation. The parameter names in different scenarios are as follows:
    • Region Type I scenario:

      Cascading system: Cascading-ExternalOM-Reverse-Proxy

      Cascaded system: Cascaded-ExternalOM-Reverse-Proxy

    • Region Type II and Region Type III scenarios: ExternalOM-Reverse-Proxy

  9. Run the following command and enter the password of user root to switch to user root:

    su - root

    The default password of user root is Huawei@CLOUD8!.

  10. Run the following command to disable user logout upon system timeout:

    TMOUT=0

  11. Run the following command to import environment variables:

    source set_env

    Information similar to the following is displayed:

      please choose environment variable which you want to import: 
      (1) openstack environment variable (keystone v3) 
      (2) cps environment variable 
      (3) openstack environment variable legacy (keystone v2) 
      (4) openstack environment variable of cloud_admin (keystone v3) 
      please choose:[1|2|3|4] 

  12. Enter 1 to enable Keystone V3 authentication and enter the password of OS_USERNAME as prompted.

    Default account format: DCname_admin; default password: FusionSphere123.

  13. Run the nova instance-action-list command to obtain the VM operation record and check whether the VM is frequently restarted.

    • If yes, go to 14.
    • If no, the server is abnormal. In this case, go to 16.

  14. Wait until the user does not frequently restart the VM, and then go to 15.
  15. Wait for 5 minutes, and check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 16.

  16. Contact technical support for assistance.
