  • host_id: specifies the ID of the host accommodating the VM for which the alarm is generated.
  • hostname: specifies the name of the host accommodating the VM for which the alarm is generated.

Impact on the System

Communication for abnormal NICs is adversely affected.

Possible Causes

  • Backend device of NICs is down due to misoperations.
  • Backend device of NICs is deleted due to misoperations.

Procedure

  1. Check whether the alarm is automatically cleared.

    • If yes, no further action is required.
    • If no, go to 2.

  2. 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

  3. 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!.

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

    TMOUT=0

  5. 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] 

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

    Default account format: DCname_admin; default password: FusionSphere123.

  7. Run the nova live-migration VM ID Host ID command to migrate the VM to another host.

    NOTE:
    • VM ID: indicates the UUID in Additional Info.
    • Host ID: indicates the ID of an available host. The host resource must meet the specifications of the VM. Note that the host ID is not that in the alarm details. To obtain the host ID, perform the following steps:
      1. Run the cps host-list command to obtain all host IDs.
      2. Run the nova hypervisor-show Host ID command to check whether the host resource meets the requirements.

  8. After 3 to 5 minutes, check whether the alarm is cleared.

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

  9. Contact technical support for assistance.
