15.6.2 Alternative to Rollback after "Secondary SC Upgrade" Phase
During Version 2.1 to Version 3.0 Upgrade
During Online Software Upgrade from version 2.1 to version 3.0, if a failure occurs
after the Secondary SC Upgrade step you are required to downgrade the OS on at
least one of the SC board.
We strongly recommend performing a regular rollback procedure and returning to the
previous software version as described above. However, some customers may wish
to continue with the upgrade even though media gateway service is down until the
process is completed.
To continue installing the new version, take these 4 steps:
1. Remove the Primary SC board from the chassis.
2. From the Secondary SC board, remove the "upgrade in progress" marker by typing
rm –f /Upgrade/UpgradeInProgress.ini. Press Enter.
client208::~# rm –f /Upgrade/UpgradeInProgress.ini
3. Reboot the Secondary SC by typing reboot. Press Enter.
client208::~# reboot
The Secondary SC board (with the new software) resets all of the Media Gateway
boards and ES boards when it restarts and upgrades them with the new software.
4. Replace the failed SC board (refer to 'SC Board Replacement Procedure' on page
142) or contact Nortel for assistance in repairing the failed SC software.
15.7 Online Software Upgrade Wizard on a Simplex
Configuration
The Online Software Upgrade on simplex configuration (only one SC board available)
is similar to the Online Software Upgrade described above. However, the Wizard
stages contain the upgrade of only the one SC board.
Upgrade from version 2.1 to version 3.0 in a simplex configuration is not supported
(because of complexity of SC board's OS upgrade). However upgrade between
version 3.0 and from version 3.0 to version 3.2 is fully supported.
15.8 Upgrade from Version 2.1 to Version 3.0 –
Disabled New Features
The following features that are normally enabled during a straight version 3.0
installation are disabled after Online Software Upgrade from version 2.1. The user
should manually enable them after the Online Software Upgrade is finished.
