Contributors Download PDF of this page
Before and after you revert, or downgrade a cluster, you should verify the status of your disks, aggregates, and volumes.
Verify disk status:
To check for… Do this…
Display any broken disks:
storage disk show -state broken
Remove or replace any broken disks.
Disks undergoing maintenance or reconstruction
Display any disks in maintenance, pending, or reconstructing states: `storage disk show -state maintenance
reconstructing` .. Wait for the maintenance or reconstruction operation to finish before proceeding.
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.
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.
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.
