3.5 Database Backup and Restore
When dual TCC+ cards are installed in the ONS 15454, each TCC+ card hosts a separate database;
therefore, the protect card’s database is available if the database on the working TCC+ fails. You can
also store a back-up version of the database on the workstation running CTC. This operation should be
part of a regular ONS 15454 maintenance program at approximately weekly intervals, and should also
be completed when preparing an ONS 15454 for a pending natural disaster, such as a flood or fire.
Caution E1000-2 cards lose traffic for approximately 90 seconds when an ONS 15454 database is restored.
Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm will appear
and clear during this period.
Caution If you are restoring the database on multiple nodes, wait five minutes between each database restore.
Procedure: Back up the Database
Step 1 Log into CTC.
Step 2 Click the Maintenance > Database tabs.
