Upgrading storage nodes

You must use the HealthTools suite of tools to upgrade storage node software. You must use management node 11.0, 11.1, or later to use the latest HealthTools suite of tools.

Important: If you are upgrading an H610S series node to Element 11.8 or later, you will use a different process than described here. See Upgrading H610S storage nodes to Element 11.8 or later.

The software upgrade process includes the following tasks.

Upgrade workflow diagram

There are two management node upgrades depicted in the workflow. The first upgrade is necessary if you do not have management node 11.0 or 11.1. You must have one of these versions to download the latest HealthTools. The second management node upgrade to version 11.8 can be performed after your cluster has been upgraded to the latest Element version.

For dark site upgrades for HealthTools and storage nodes, use the dark site procedure for a given step.
