You must use the HealthTools suite of tools to upgrade storage node software. You must use management node 11.0 or 11.1 to use the latest HealthTools suite of tools.
The software upgrade process includes the following tasks.
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 is optional and can be performed after your cluster has been upgraded to 11.3.
Note: Certain operations are suppressed during an upgrade, such as adding and removing nodes, adding and removing drives, and commands associated with initiators, volume access groups, and virtual networks, among others.
Upgrading HealthTools and storage nodes from a dark site involves a different process.
