Clear the upgrade directory from both servers before reattempting further upgrades using the command rm -fr /var/log/sonus/upgrade/*
under all the following conditions:
This section describes the different methods to upgrade the SBC Core (SBC 5000 series, SBC 7000 series and SBC SWe) application.
When anSBC upgrade is available, the software is posted on the Ribbon Support Portal. Refer to Downloading Software from the Ribbon Support Portal for more information.
Ensure the SBC SWe memory reservation meets the requirements for the current release. Refer to SBC SWe Performance Metrics.
The disk space used during the upgrade process depends on how the hypervisor internally handles the disk lifecycle for an instance. The following table shows Ribbon's recommendation for extra disk space for different types of nodes/instances: Disk Space Requirements Extra* Disk Space (in GB) *Extra disk space applicable only during the upgrade process, in addition to the disk space requirement for the instance. Total disk space requirement during upgrade = Disk Space for the upgraded instance + extra disk space required only during upgrade ** Starting with SBC v07.01.00, SBC Configurator is discontinued.Minimum Disk Space Requirements for SWe Upgrades
Node Type S-SBC 80 M-SBC 80 SBC-CONFIG** 80 PSX-M 360 PSX-S 360 PSX-Test 360 EMS_SA 150
LSWU allows a user to upgrade the SBC application software on HA pairs without impacting service (dropping calls). This is mainly recommended for HA SBC systems. LSWU can also be performed on SBC EMA and SBC EMA Platform Mode. Refer to Live Software Upgrade using CLI and System Administration - Software Install-Upgrade for more information.
The non-LSWU upgrade process requires taking the SBC system offline to perform the application upgrade. This section describes upgrading the SBC application in a standalone or HA configuration using the Platform Manager or EMA Platform Mode. The Platform Manager tool is used to upgrade the SBC application from the 3.x/4.x release to the 5.0 release. Beginning with 5.0 release, the Platform Manager was integrated into EMA and is referred to as EMA Platform Mode. Thus, post 5.0 SBC application upgrades are performed using EMA.
Refer to Upgrading SBC Application Using Platform Manager or Upgrading SBC Application using EMA Platform Mode for more information.
Once the upgrade is complete, rediscover the SBC from the EMS, if present, and edit any attributes that may have been modified post-upgrade. Attributes are listed under the EMS pages Register Sonus SBC Core Node or Register an SBC 5x00 Node.
