Recovering if the Primary Appliance Fails
If the primary Skylight orchestrator appliance is unavailable, service can be recovered by switching to the secondary appliance as explained in this section.
Restoring the Data Store on the Secondary Appliance
The first step is to restore the most recent backup of the data store (from the primary appliance) on the secondary appliance. Then you start the Skylight orchestrator software on the secondary appliance.
Search for the latest backup that was transferred from the primary appliance to the secondary appliance:
ls -l /data/backupsTake note of the name of the latest backup file. You may want to write it down.
Restore the latest backup.
For example, if the latest backup file for the primary appliance is named:
DBDUMP_2021-12-12_14:55:01.bkp.gz
You would enter these two commands:
cd /opt/accedian/skylight/scripts
./ems_restoredb_mysql.sh /data/backups/DBDUMP_2021-12-12_14:55:01.bkp.gzUsing a console, log in to the secondary appliance as the visionems user.
Start the Skylight orchestrator web interface on the secondary appliance as follows:
service start app_server
Skylight orchestrator software should now be running on the secondary appliance.
Verifying the Switch to the Secondary Appliance
The final step is to verify the network inventory and ensure that the Skylight orchestrator web interface is operational on the secondary appliance.
Using a supported web browser, log in to the Skylight orchestrator web interface on the secondary appliance.
Click the logo (upper left corner of the page) to display the About Skylight orchestrator dialog and check that the BuildVersion is 21.08.
Select the Devices ▶ Managed Elements page and verify that the total count of Skylight devices (bottom left corner of page) is accurate.
Click the icon (in bottom left corner) and verify that the current alarm count is accurate.
Select the Commission ▶ Jobs page and verify that pre-existing configuration jobs are present.
Select the Collection ▶ Reporting Status page and verify that:
- The complete list of managed devices is displayed.
