[ScreenOS] Configurations are out of sync after upgrading one device to 6.3r21 and higher



Article ID: KB30693 KB Last Updated: 23 Dec 2015Version: 1.0

After upgrading one cluster member from 6.3r19 or earlier to 6.3r21 and later, will report as configuration out of sync.


On upgrade, the following error is shown:

Failed command - set zone "MGT" block

This command is depreciated. In prior versions, it was set in the configuration by default, but you could not unset/remove the command.


This is per design. In prior versions, the command was present in the configuration, but could not be changed (unset). As such, the command is not needed in the configuration.

Due to this change in design, the configurations will show as out of sync on the upgraded device. Once both devices are upgraded, the configurations should show as in sync.
