Before joining the newly installed nodes to the cluster, you must ensure that they are running the same version of ONTAP that the cluster is running. If the nodes are running a different version, you must upgrade or downgrade the nodes to match the cluster. For downgrading node(s), contact technical support.
- Determine the version of ONTAP installed on the cluster: cluster image show
- View the current version of ONTAP on the nodes:
- On the first node, view the software version: system node image show
Example
cluster1::> cluster image show
Node Current Version Installation Date

- Repeat the previous step for the second node.
- Compare the versions of ONTAP on the cluster and the nodes, and perform either of the following actions:
- If the versions are the same, skip the remaining steps in this procedure.
- If the versions are different, install a different version of ONTAP on the nodes by following the remaining steps of this procedure.
