Upgrade software and firmware for multiple controllers
You can use SANtricity Unified Manager to upgrade the SANtricity OS software on multiple storage arrays of the same type to a newer version.
Perform pre-upgrade health check
A health check runs as part of the upgrade process, but you also can run a health check separately before you begin. The health check assesses components of the storage array to make sure that the upgrade can proceed.
Transfer software files to the controllers
You load the SANtricity OS software file and the NVSRAM file into the repository so it is accessible to the Unified Manager Upgrade Center.
Activate staged software files (optional)
You can choose to activate the software file immediately or wait until a more convenient time. This procedure assumes you chose to activate the software file at a later time.
