This document covers the procedure and the tools for applying minor upgrade across the range of Sentinel products.

General information

A minor upgrade of a Sentinel product is when a customer wants a new product where the version differs on the fourth component: for example VoLTE to or to

As a policy there is full backwards compatibility between minor releases. There might be new features, new configuration and bug fixes, but no architecture changes.

The products supported by minor upgrade are:

  • Sentinel VoLTE

  • Sentinel IP-SM-GW

  • Sentinel GAA

  • Rhino Element Manager (REM)

  • Rhino

On how to minor upgrade Sentinel products see Minor Upgrade Sentinel Product.

On how to upgrade REM see Upgrade Rhino Element Manager

Requirements for a minor upgrade

To be able to apply a minor upgrade for Sentinel successfully verify the checklist below:

check connectivity

Check the connectivity between the management node and the Rhino nodes. From the management node you must be able to open an SSH connection to each Rhino node without specifying a password.

check the upgrade bundle

The upgrade bundle for a Sentinel product consists of:

Item Description

The orca tool

helpers directory

Contains set of scripts used by orca

core directory

workflows directory

resources directory

Contains the properties used by orca

licenses directory

License information for third party libraries used by the patch runner

packages directory

Contains package files and the package.cfg

The package files directory contains:

  • the packages.cfg file

  • the SDK in offline mode

  • a rhino install (optional)

  • a rhino config JSON file (optional)

  • a license (optional)

  • a new JDK (java) (optional)

The offline SDK must contain the product SDK with an offline repository and the product installer.

See Creating a minor upgrade bundle for more information.

check the path structure

For Sentinel products, the requirements are that the Rhino nodes have the expected path structure:

enable symmetric activation state mode

Symmetric activation state mode must be enabled prior to starting the upgrade. To check that it is enabled, use orca's status command. At the top under the Global info header there will be the text Symmetric activation state mode is currently enabled if it is enabled, or Nodes with per-node activation state: <node list> if it is disabled. Alternatively you can use the rhino-console command getsymmetricactivationstatemode.

To enable it, follow the instructions in the Rhino documentation.
