The software upgrade takes approximately one hour to one and a half hours to complete per appliance.
NOTE:The cluster temporarily stops recording performance metrics when the primary node of the primary appliance reboots during the software upgrade.
After you are returned to the login screen, close the browser session and open a new session before logging in again to refresh the UI.
NOTE:Following the upgrade, if you do not open a new browser session before logging in again,
PowerStore Manager still displays the UI for the previous
PowerStoreOS version. New features will not be available until you refresh the browser.
Results
During the software upgrade process, the primary node of the primary appliance fails over to the secondary node of the appliance and you are disconnected from
PowerStore Manager. You can log back in to
PowerStore Manager after the failover process is complete.
When a new version of the
PowerStoreOS is installed, the column layout settings in
PowerStore Manager tables reset to their default layout. Changes to the column layout settings in
PowerStore Manager do not persist when the
PowerStoreOS is upgraded.
NOTE:Beginning with PowerStoreOS 4.0.x and later, if the software upgrade fails and successfully rolls back to the previous operating system version, the system automatically recovers. You can retry the upgrade by selecting the package and then
Upgrade again. Contact your service provider for further assistance with nondisruptive upgrade (NDU) failures.
