Use this procedure to upgrade SBC HA pairs. If you have more than one SBC server pair in your HA deployment, repeat this procedure for each HA pair of servers.
You must upgrade using the following order:
Upgrade the primary EMS.
Upgrade the SBC systems in any order. For an HA pair, upgrade the secondary SBC first followed by the primary SBC to avoid failover conditions that might interfere with the upgrade.
Upgrade the secondary EMS.
Before you begin
Ensure that the primary EMS server is upgraded before upgrading HA pair servers.
Ensure that the status of the HA SBC servers or the separate SBC server is in the Commissioned (Upgrade Required) state.
Ensure the upgrade package is copied to the SBC HA pair. For more information, see Copying upgrade package to Avaya SBC HA pair servers or single Avaya SBC server.
Log in to the primary EMS web interface with administrator credentials.
Navigate to Device ManagementUpdates.
Click Upgrade.
STEP RESULT:
The system displays the Upgrade Devices window. Select the devices you want to upgrade. The system determines whether you must upgrade one device at a time. That is, more than one device might need an upgrade, but only those devices that are active in the window can be selected. For example, if you have an HA pair of SBC devices, you must upgrade the primary SBC before you upgrade the secondary SBC.
Important:
If you get a message stating that the selected upgrade package has been tampered with or that it has not be signed with a trusted PGP key, the upgrade cannot continue. This could be caused by a number of factors:
The upgrade package has been compromised or is corrupt.
The upload of the upgrade package was incomplete, which sometimes happens using older versions of Internet Explorer.
The ASC file is not in place.
Click Finish to close the error message and correct any possible errors before starting the upgrade again.
Select the check box in the Device Name column that you want to upgrade.
Click Next.
STEP RESULT:
The system starts the upgrade. You can click View Log to view the log file to follow the progress of the upgrade or you can just wait for the status bar to complete. The log file cannot be viewed when the device is rebooting.
The upgrade process takes some time. Do not try to manually reboot the server when an upgrade is in progress. After the upgrade is complete, the system displays a message indicating that the upgrade is complete. You can click View Log again to view the upgrade messages.
Click Finish.
ADDITIONAL INFORMATION:
The system returns to the Device Management with the Updates tab selected.
Note:
Until all of the SBC devices managed by this EMS have been upgraded, the EMS displays the following message for SBC HA pairs on the Updates tab:
One or more devices are in an upgrade required state. If you would like to upgrade these devices now, please click the Upgrade button below. You may also choose to rollback your EMS at this point.
HA system pairs and all other SBC systems must be upgraded before this message is resolved.
If the EMS server becomes non-functional during the upgrade, after the upgrade is complete, you must enable the EASG feature manually to allow the EASG logins for the customers.
Do one of the following steps:
If you have more devices to upgrade, click Upgrade to repeat this procedure and upgrade the next SBC device.
If you have upgraded all SBC devices that require an upgrade, select the Devices tab to confirm that all devices are upgraded to the correct version and that the status shows Commissioned. You can also run the ipcs-version command from the command line interface to view the current version and status of the EMS and SBC.
