Warning
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:
- There is a need to revert the upgraded server after a single server upgrade while the peer is still on an older version.
- A revert will be performed by doing a re-ISO.
This section describes the different methods to upgrade the
Unable to show "metadata-from": No such page "_space_variables"
(SBC 5000 series, SBC 7000 series and SBC SWe) application.
When an
Unable to show "metadata-from": No such page "_space_variables"
upgrade is available, the software is posted on the Ribbon Support Portal. Refer to
Downloading Software from the Ribbon Support Portal for more information.
Prerequisities
Prior to performing an upgrade on the
Unable to show "metadata-from": No such page "_space_variables"
, ensure the following activies are accomplished.
For Unable to show "metadata-from": No such page "_space_variables"
(in general):
- Before upgrading the ConnexIP OS, firmware, and the
Unable to show "metadata-from": No such page "_space_variables"
application, you must first save the configuration in case you encounter any issues during the upgrade. Before upgrading the application, upgrade the SBC firmware to the latest version on both the active and standby SBCs for an HA pair.

:
Increase the memory to the larger of:
- the minimum memory required for the release.
or - the memory required for the desired session capacity.
Unable to show "metadata-from": No such page "_space_variables"
instances configured with only 12 GB of RAM have lower capacity limits than instances with higher memory configurations, thus they may not perform at optimum capacity. Contact your Ribbon representative to order DIMM kits to increase the RAM to 24 GB.For
Unable to show "metadata-from": No such page "_space_variables"
memory requirements for the current release, and a procedure to upgrade memory, refer to SBC SWe Performance Metrics.
Complete the procedure to upgrade memory prior to performing the upgrade.
- Ensure the

memory reservation meets the requirements for the current release. Refer to SBC SWe Performance Metrics.
Minimum Disk Space Requirements for SWe Upgrades
The following table shows Ribbon's recommendation for extra disk space for different types of nodes/instances:
Node Type | Extra Disk Space* (in GB) |
---|
S-SBC | 80 |
M-SBC | 80 |
PSX-M | 360 |
PSX-S | 360 |
PSX-Test | 360 |
EMS_SA | 150 |
Live Software Upgrade (LSWU)
LSWU allows a user to upgrade the
Unable to show "metadata-from": No such page "_space_variables"
application software on HA pairs without impacting service (dropping calls). This is mainly recommended for HA SBC systems. LSWU can also be performed on Unable to show "metadata-from": No such page "_space_variables"
EMA and in Unable to show "metadata-from": No such page "_space_variables"
EMA Platform Mode. Refer to Live Software Upgrade using CLI and System Administration - Software Install-Upgrade for more information.Non-Live Software Upgrade (Non-LSWU)
The non-LSWU upgrade process requires taking the SBC system offline to perform an application upgrade. This refers to upgrading the
Unable to show "metadata-from": No such page "_space_variables"
application in a standalone or HA configuration using EMA Platform Mode. Refer to
Upgrading SBC Application using EMA Platform Mode for more information.
