Upgrade readiness for PowerStore T model clusters Review the following considerations before upgrading a PowerStore T model cluster: ● Download the latest version of the PowerStore Release Notes to determine which software upgrade packages are required to perform the PowerStore upgrade. ● You can upload up to ten upgrade packages on your PowerStore cluster at one time. However, after an upgrade starts, it must be successfully completed across all appliances in the cluster before another upgrade can be performed. ● The node of the cluster that is running the management software is designated as the primary node of the primary appliance. During the software upgrade process, you are disconnected from PowerStore Manager when the primary node on the primary appliance fails over to the peer node of the appliance. You can log back in to PowerStore Manager after the node failover process is complete. NOTE: For a PowerStore cluster with two appliances, you are disconnected from PowerStore Manager again when the second appliance performs its failover process. However, a second disconnect from PowerStore Manager does not occur during the failover process for PowerStore clusters with three or more appliances. ● If you change CHAP settings on a PowerStore T model cluster with NAS enabled, such as enabling or disabling CHAP, changing mutual CHAP to single CHAP, or changing single CHAP to mutual CHAP, you must perform the following actions: ○ Reboot the cluster nodes one at a time as soon as possible after changing the CHAP settings. 6 PowerStore T model clusters
