Beginning with SBC Core release 12.0, the SBC interoperates with the Ribbon Application Management Platform (RAMP), replacing the Insight EMS.
However, the EMA, CLI and API will continue to include EMS-labeled parameters and screens to facilitate SBC migrations from older releases. Accordingly, any references to "EMS" in this documentation apply to the RAMP platform.
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:
In this section:
This section describes the different methods to upgrade the SBC Core application.
When an SBC upgrade is available, the software is posted on the Ribbon Support Portal. Refer to Downloading Software from the Ribbon Support Portal for more information.
Prior to performing an upgrade on the SBC Core, ensure the following activities are accomplished.
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 performance/capacity of the SBC SWe is impacted by the amount of memory assigned to the VM. Review SBC SWe Performance Metrics to see the memory requirements for the current release plus a procedure to upgrade memory, if required. Complete the procedure to upgrade memory prior to performing the upgrade.
The amount of disk space used during the upgrade process depends on how the hypervisor internally handles an instance's disk lifecycle. The following table provides Ribbon's recommendation for extra disk space for different types of nodes/instances.
For proper performance, you must provide the minimum resources shown here.
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 |
To recover from a mismatch in session estimates in an HA pair, refer to Recovering from Default Indices in 1:1 HA SBC SWe, if applicable.
The E1000E network interface type is unsupported in VMware.
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. You can also perform a LSWU on the SBC EMA and in SBC EMA Platform Mode. Refer to Live Software Upgrade using CLI and System Administration - Software Install-Upgrade for more information.
On SBC setups, the active node takes more time than expected for the services to come up after an upgrade from 11.1.0x. Before performing an upgrade from 11.1.0x, apply the following steps:
[root@SBC]# $ENCRYPTED_STORE_SH cnxipmadmin
The command must not show the default password "Cnx1PmAdm1n
"
[root@SBC]# $CHANGE_DEFAULT_PASSWDS_SH
[root@SBC]# $ENCRYPTED_STORE_SH cnxipmadmin
The non-LSWU upgrade process requires taking the SBC system offline to perform an application upgrade. This refers to upgrading the SBC application in a standalone or HA configuration using EMA Platform Mode. Refer to Upgrading SBC Application using EMA Platform Mode for more information.
Once the upgrade is complete, rediscover the SBC from the RAMP, if present, and edit any attributes that may have been modified post-upgrade. Attributes are listed under the RAMP page Register an SBC Core Device.
