Contributors netapp-aherbin netapp-thomi Download PDF of this topic

You can switchover from one MetroCluster site to the other to perform maintenance or recover from an issue.

Steps
  1. Click (Return to classic version).

  2. Click Configuration > MetroCluster.

    System Manager verifies whether a negotiated switchover is possible.

  3. Perform one of the following substeps when the validation process has completed:

    1. If validation fails, but Site B is up, then an error has occurred. For example, there might be a problem with a subsystem, or NVram mirroring might not be synchronized.

      1. Fix the issue that is causing the error, click Close, and then start again at Step 2.

      2. Halt the Site B nodes, click Close, and then perform the steps in Performing an unplanned switchover.

    2. If validation fails, and Site B is down, then most likely there is a connection problem. Verify that Site B is really down, then perform the steps in Performing an unplanned switchover.

  4. Click Switchover from Site B to Site A to initiate the switchover process.

  5. Click Switch to the new experience.
