Updating clusters

You can use Storage Manager to update a cluster or the individual nodes in an high-availability (HA) pair. To perform an update, you should select an ONTAP image, validate that your cluster or the individual nodes in the HA pair are ready for the update, and then perform the update.



  • Obtaining ONTAP software images
    Using ONTAP 9.4 and later, you can copy the ONTAP software image from the Lenovo Data Center Support site to a local folder. This only applies to ONTAP 9.4 patch updates. For upgrades from ONTAP 9.3 or earlier, you must copy the ONTAP software image to an HTTP or FTP server on your network.
  • Updating a cluster nondisruptively
    You can use Storage Manager to update a cluster or individual nodes in high-availability (HA) pairs without disrupting access to client data.
  • How to update a cluster nondisruptively
    You can use Storage Manager to update a cluster nondisruptively to a specific ONTAP version. In a nondisruptive update, you have to select an ONTAP image, validate that your cluster is ready for the update, and then perform the update.
  • Cluster Update window
    You can use the Cluster Update window to perform an automated cluster update nondisruptively.
