Completing post-upgrade or downgrade tasks for the cluster

After you upgrade or downgrade a cluster to a different version of ONTAP software, you must complete additional tasks to restore normal operation.

  1. Verifying the cluster version
    After all of the HA pairs have been upgraded, you must use the version command to verify that all of the nodes are running the target release.
  2. Verifying cluster health (verifying storage health)
    Before and after you upgrade, revert, or downgrade a cluster, you should verify that the nodes are healthy and eligible to participate in the cluster, and that the cluster is in quorum.
  3. Verifying storage health (completing post-upgrade or downgrade tasks)
    Before and after you upgrade, revert, or downgrade a cluster, you should verify the status of your disks, aggregates, and volumes.
  4. Verifying your network configuration after upgrade
    ONTAP 9.8 and later automatically monitors layer 2 reachability. After you upgrade from ONTAP 9.7x or earlier to ONTAP 9.8 or later, you should verify that each .network port has reachability to its expected broadcast domain.
  5. Verifying networking and storage status for MetroCluster configurations (post-upgrade or downgrade)
    Before and after performing an update in a MetroCluster configuration, you should verify the status of the LIFs, aggregates, and volumes for each cluster.
  6. Verifying the SAN configuration after an upgrade
    If you are upgrading in a SAN environment, then after the upgrade, you should verify that each initiator that was connected to a LIF before the upgrade has successfully reconnected to the LIF.
  7. Reconfiguring KMIP server connections after upgrading to ONTAP 9.5 or later
    After performing an upgrade to ONTAP 9.5 or later, you must reconfigure your external key management (KMIP) server connections.
  8. Enabling and reverting LIFs to home ports (post-upgrade or downgrade tasks for the cluster)
    During a reboot, some LIFs might have been migrated to their assigned failover ports. Before and after you upgrade, revert, or downgrade a cluster, you must enable and revert any LIFs that are not on their home ports.
  9. Relocating moved load-sharing mirror source volumes
    After successfully completing a nondisruptive upgrade, you can move load-sharing mirror source volumes back to the locations they were in originally before the upgrade.
  10. Resuming SnapMirror operations
    After completing a nondisruptive upgrade or downgrade, you must resume any SnapMirror relationships that were suspended.
