About hypervisor cluster profile consistency validation

HPE OneView automatically checks the consistency of the hypervisor cluster profile. Consistency checking is validating the hypervisor cluster profile to ensure:

  • The configurations of the cluster, and the hypervisors in the cluster, match the intended configurations in the hypervisor cluster profile.

  • The intended configurations on the hypervisor cluster profile, such as networking and storage configurations, are valid with the configurations defined in the associated server profile template.

  • The server profiles linked to the member hypervisor profiles match the intended configurations defined in the server profile template.

Situations that lead to inconsistencies
  • Hypervisor cluster profile is configured differently than the server profile template

    The network and storage configurations of the hypervisor cluster profile are validated with the configurations on the server profile template and networks.

    NOTE:
    • If you add or remove a network in the server profile template, the vSwitches in the hypervisor cluster profile must be configured for the changed networks.

    • If you add or remove a storage volume in the server profile template, the storage of the hypervisor cluster profile must be configured for the changed storage volumes.

    Alert

    The hypervisor cluster profile is not consistent with its server profile template - This alert appears, and requires manual remediation.

    Manual remediation

    Perform the instructions in the alert, and edit the hypervisor cluster profile. This action fixes the inconsistencies in the hypervisor cluster profile configuration. The vSwitch configuration is automatically rebuilt based on the connections defined in the server profile template. The storage volumes in the hypervisor cluster profile are automatically added or allowed to be removed to match the server profile template.

  • vCenter hypervisor cluster is inconsistent with the hypervisor cluster profile definition

    The hypervisor cluster and its configurations are validated with the hypervisor cluster profile definition.

    NOTE:

    If you make any of the following changes in either HPE OneView or VMware vCenter, it will result in mismatch and inconsistencies.

    • Change the name fo the cluster

    • Enable or disable VMware Distributed Resource Scheduler (DRS)

    • Enable or disable VMware High Availability

    Alert

    Cluster is inconsistent - This alert appears with the Make cluster consistent link.

    Automatic remediation

    Perform the instructions in the alert. The Make cluster consistent option nondisruptively fixes all the inconsistencies of the hypervisor cluster to match the hypervisor cluster profile definition. The inconsistent fields are automatically updated with the values from the hypervisor cluster profile to resolve inconsistencies.

  • One or more hypervisor profiles are inconsistent with the hypervisor cluster profile

    The hypervisors are validated with the hypervisor cluster profile definition. The inconsistencies in the server profile associated with the hypervisor profile are treated as inconsistencies in the hypervisor profile. These inconsistencies roll up to the hypervisor cluster profile.

    NOTE:
    • If you change network and storage configurations in the hypervisor cluster profile to match the server profile template, it will result in inconsistences of its associated hypervisor profiles.

    • If changes to the hypervisor profiles occur due to any of the following changes, will result in inconsistencies with the corresponding hypervisor cluster profile.

      • Changes in the server profile cause server profile inconsistency.

      • Changes in the server profile template cause inconsistent server profiles.

      • Changes made to the hypervisors using a hypervisor manager outside of HPE OneView cause inconsistent hypervisor configurations.

    • If the hypervisor cluster profile is configured to not manage vSwitches, then the vSwitches and port groups are not validated for consistency.

    Alert

    1 or more hypervisor profiles are inconsistent - This alert appears with the Make hypervisor profiles consistent link.

    Automatic remediation

    For inconsistencies that allow automatic remediation, perform the instructions in the alert. The Make hypervisor profiles consistent option nondisruptively fixes all the inconsistencies of the hypervisor profiles in the hypervisor cluster profile. It sequentially addresses one active hypervisor profile at a time. If the fix causes downtime, HPE OneView places the hypervisor in maintenance mode, fixes the inconsistencies, and moves the hypervisor back to active mode. If a hypervisor profile fails anytime during the process, the task is aborted. All inconsistent hypervisor profiles within the cluster are updated with the values from the hypervisor cluster profile to resolve inconsistencies.

    NOTE:

    The remediation fails when you modify the port group name that is being used by VMs running in the cluster.

    Manual remediation

    For inconsistencies that require manual remediation, perform the manual instructions listed in the Make hypervisor profiles consistent alert.

  • Both the cluster and one or more hypervisor profiles are inconsistent

    The hypervisor cluster and its configurations are not consistent with the hypervisor cluster profile definition. The hypervisors are not consistent with the hypervisor cluster profile definition.

    Alert

    Cluster and 1 or more hypervisor profiles are inconsistent - This alert appears with the Make cluster and hypervisor profiles consistent link.

    Automatic remediation

    Perform the instructions in the alert. The Make cluster and hypervisor profiles consistent option nondisruptively fixes the inconsistencies of the hypervisor cluster, and the hypervisor profiles.

    NOTE:

    Hypervisor cluster and hypervisor consistency checks are computed after any hypervisor cluster profile or hypervisor profile operations. Checks are also computed for hypervisor cluster or hypervisor configurations changes that are managed using the hypervisor cluster profile. HPE OneView checks the hypervisor manager events to identify these changes at a regular interval of two minutes.

    In a scaled setup, the hypervisor manager events take more time to arrive. In such environments, it may take a maximum of 10 minutes for consistency check alerts to be raised or cleared.
