SECURING
Vault administrators should always use theID Vaults -> Manage tool to add or remove vault servers because the tool manages vault server information in the vault configuration document in the Domino Directory and in the vault database. Do not use Notes® menu commands or the database replication tool in the Domino Administrator to add or remove vault replicas.
Environments with many users are likely to see performance benefits to using multiple vault servers, and any environment can benefit from failover that multiple vault servers can provide. It is important that replication occurs regularly among vault servers, either through clustered or scheduled replication. Replication conflicts are managed automatically and are not a concern.
When there are multiple vault servers, one is designated as the vault primary server. This server carries out some vault operations related to name changes and key rollover to avoid replication conflicts. It is also the server from which the last vault replica is deleted if you delete the entire vault configuration. The primary server is shown with a checkmark in the ID Vaults -> Manage tool. It is also the first server listed when you issue the show idvaults command.
