Cluster Update tab

Command buttons

Refresh
Updates the information in the window.
Select
You can select the version of the software image for the update.
  • Cluster Version Details: Displays the current cluster version in use and the version details of the nodes or HA pairs.
  • Available Software Images: Enables you to select an already available software image for the update. Alternatively, you can download a software image from the NetApp Support Site and add it for the update.
Validate
You can view and validate the cluster against the software image version for the update. A pre-update validation checks whether the cluster is in a state that is ready for an update. If the validation is completed with errors, a table displays the status of the various components and the required corrective action for the errors.

You can perform the update only when the validation is completed successfully.

Update
You can update all the nodes in the cluster or an HA pair in the cluster to the selected version of the software image. While the update is in progress, you can choose to pause and then either cancel or resume the update.

If an error occurs, the update is paused and an error message is displayed with the remedial steps. You can choose to either resume the update after performing the remedial steps or cancel the update. You can view the table with the node name, uptime, state, and Data ONTAP version when the update is successfully completed.
