Reviving an Eon Mode database on GCP in MC

An Eon Mode database keeps an up-to-date version of its data and metadata in its communal storage location. After a cluster hosting an Eon Mode database is terminated, this data and metadata continue to reside in communal storage. When you revive the database later, Vertica uses the data in this location to restore the database in the same state on a newly provisioned cluster.

Follow these steps to revive an Eon Mode database on GCP:

  1. On the MC home page, click Revive Eon Mode Database. MC launches the Provision and Revive an Eon Mode Database wizard.

  2. On the first page of the wizard, enter the following information:

    • Google Cloud Storage HMAC Access Key and HMAC Secret Key: Copy and paste the HMAC access key and secret you created when you created the database. See Eon Mode on GCP prerequisites for details.

    • Zone: This value defaults to the zone containing your MC instance. Make this value the same as zone containing the Google Cloud Storage bucket your database will use for communal storage. You will see significant performance issues if you choose different zones for cluster instances, storage, or the MC.

    • CIDR Range: The IP address range for clients you want to grant access to your database. Make this range as restrictive as possible to limit the exposure of your database.

  3. Click Next. On the second page of the wizard, set Google Storage Path for Communal Storage of Database to the URL of the communal storage bucket for the Eon Mode database to revive. For requirements, see Eon Mode on GCP prerequisites.

  4. Click Discover. MC displays a list of all Eon Mode databases available on the specified communal storage location.

  5. Select the database to revive. MC prepopulates the choices for the Data, Depot, and Temp catalogs, using the same machine types and configuration choices used when the database was created.

  6. Click Next. Review the summary of all your database settings. If you need to make a correction, use the Back button to step back to previous pages of the wizard.

  7. When you are satisfied with the database settings, check the Accept terms and conditions box and click Revive Database.

MC displays a progress screen while creating the cluster and reviving the database onto it, a process which takes several minutes. After it completes successfully, the MC displays a Get Started button. This button leads to a page of useful links for getting started with your new database.
