This document gives the procedure to upgrade a 7000 cluster

The service manual documentation can be found here :

Goal

This document is to provide a guidance for doing a cluster update the correct way.

There are two separate cluster configurations and processes :

  1. Active-Active Cluster
  2. Active-Passive Cluster
  3. Clustered nodes must be upgraded one right after the other.
Important requirement: Before starting the maintenance window, make sure the gzipped firmware tarball has been downloaded and saved on a local host, available to the NAS box in ftp or http.
Review the Release Notes carefully for every version between installed version and version you are going to update to.

 

Warning: Clustered nodes CANNOT be left at two different code versions longer than 8 hours.  Systems left at two different code versions can corrupt data and cause an outage for days in order to repair.
