A SVST alarm may be an indication that you need to rebuild the DDS service’s Cassandra database for a Storage Node.
About this task
If Cassandra is stopped for more than 15 days (for example, the Storage Node is powered off), when it is brought back online, Cassandra will not start. You must rebuild the Cassandra database for the affected DDS service.
Attention: If two or more of the Cassandra database services are down for more than 15 days, contact technical support, and do not proceed with the steps below.
