Verifying storage health (verifying that the cluster is ready)

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

Procedure

  1. If you are preparing to upgrade, revert, or downgrade, 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
    2. 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 upgrade or 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 upgrade or 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 with the upgrade.
