Verify storage health before revert

Contributors netapp-thomi

Before and after you revert, or downgrade a cluster, you should verify the status of your disks, aggregates, and volumes.

  1. Verify disk status:

    To check for…​ Do this…​

    Broken disks

    1. Display any broken disks: storage disk show -state broken

    2. Remove or replace any broken disks.

    Disks undergoing maintenance or reconstruction

    1. Display any disks in maintenance, pending, or reconstructing states: `storage disk show -state maintenance

    pending

    reconstructing` .. Wait for the maintenance or reconstruction operation to finish before proceeding.

  2. Verify that all aggregates are online by displaying the state of physical and logical storage, including storage aggregates: storage aggregate show -state !online

    This command displays the aggregates that are not online. All aggregates must be online before and after performing a major reversion.

    cluster1::> storage aggregate show -state !online
    There are no entries matching your query.
  3. Verify that all volumes are online by displaying any volumes that are not online: volume show -state !online

    All volumes must be online before and after performing a major reversion.

    cluster1::> volume show -state !online
    There are no entries matching your query.
  4. Verify that there are no inconsistent volumes: volume show -is-inconsistent true

    If any inconsistent volumes are returned, you must contact NetApp Support before you precede.
