Running cluster verification

Edit online

After making a change to the cluster, you can perform cluster verification in several ways.

These methods include:

  • Automatic verification. You can automatically verify your cluster:
    • Each time you start cluster services on a node
    • Each time a node rejoins the cluster
    • Every 24 hours.

    By default, automatic verification is enabled to run at midnight.

    For detailed instructions, see Automatic verification and synchronization.

  • Manual verification. Using the SMIT interface, you can either verify the complete configuration, or only the changes made since the last time the utility was run.

    Typically, you should run verification whenever you add or change anything in your cluster configuration. For detailed instructions, see Verifying the PowerHA® SystemMirror® configuration using SMIT.
