The SVST alarm indicates that you might need to rebuild the Cassandra database for a Storage Node. Cassandra is used as the metadata store for StorageGRID.
About this task
If Cassandra is stopped for more than 15 days (for example, the Storage Node is powered off), Cassandra will not start when the node is brought back online. 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.
