Impact on System

EVS service provisioning may be affected by resource insufficiency in the storage pool.

Possible Causes

  • The alarm thresholds for storage pool capacity metrics are too low.
  • The resources in the storage pool at the corresponding location are insufficient.

Handling Procedure

  1. Check the alarm thresholds of Storage usage rate.

    1. Log in to ManageOne Maintenance Portal using a browser.

      URL: https://Address for accessing the homepage of ManageOne Maintenance Portal:31943, for example, https://oc.type.com:31943

      Default account: admin; default password: Huawei12#$

    2. Choose Monitoring Center > Monitoring Configuration from the main menu.
    3. In the navigation pane, choose Capacity Threshold Maintenance.
    4. Check whether the alarm thresholds for storage usage rate are proper according to the default threshold of each alarm severity.
      • If yes, a few vCPUs can be used, go to 3.
      • If no, go to 2.

  2. Reset the alarm thresholds of Storage usage rate.

    1. Click Modify in the Operation column to modify the thresholds.
    2. Wait for 10 minutes. Choose Alarms > Current Alarms from the main menu. On the displayed page, check whether the alarm is cleared.
      • If yes, no further action is required.
      • If no, after the alarm severity decreases, the alarm still exists and the updating information will be synchronized to Last Occurred on the system. Go to 3.

  3. Contact the administrator to expand the capacities of resources in storage resource pools by referring section "Capacity Expansion for Service Storage" in HUAWEI CLOUD Stack 6.5.0 Capacity Expansion Guide.

Alarm Clearance

After the fault is rectified, the alarm is automatically cleared.
