2 On the Full Configuration page, change the Server Configuration setting from Backup to Primary.
This setting converts the vCenter Operations Manager system on the backup server to serve as the new
primary server.
3 Update the server IP address, or the virtual IP address that represents the cluster, to the correct IP
address for the new primary server or cluster.
End users and remote collectors that point to the vCenter Operations Manager server must use the new
IP address.
4 Click Finish to save the configuration.
NOTE Because the vCenter Operations Manager services are reinstalled and restarted when you click
Finish, click Exit, not Finish, to close the utility if you do not make any changes.
What to do next
If you need to switch a vCenter Operations Manager replication server to the primary server, you might
need to make additional changes. See “Switch the Primary and Backup Replication Servers,” on page 129.
Backing Up and Recovering the RDB Server
vCenter Operations Manager uses commercially available relational databases. If the
vCenter Operations Manager RDB is unavailable, vCenter Operations Manager becomes unavailable. If you
require a high availability or remote failover capability, configure the RDB server to use clustering or a
remote warm backup.
Instances that are configured against a single database are unavailable if that database becomes unavailable.
If this situation occurs, a high availability strategy that includes a clustered database environment enables
the cluster to immediately switch the shared disks and the vCenter Operations Manager instance to the
backup server if one database becomes unavailable.
Backing Up and Recovering a Remote Collector Server
The vCenter Operations Manager remote collector is a remote host that has only the
vCenter Operations Manager collector installed. A remote collector does not store data. You might want to
install one or more remote collectors to navigate firewalls, reduce bandwidth across data centers, and
reduce the load on the vCenter Operations Manager server.
If a remote collector server becomes unavailable, the primary vCenter Operations Manager server does not
receive data from the portion of the monitored environment that is configured for that particular remote
collector.
Although you can install a remote collector on a cluster, typical implementations install a separate collector
on another server. This backup remote collector should have the same vCenter Operations Manager
collector adapters folder and the same vCenter Operations Manager collector configuration folder as the
primary remote collector. If the primary remote collector becomes unavailable, you can bring the backup
remote collector online.
Backing Up and Recovering a Remote DT Processor Server
A remote DT processor is a vCenter Operations Manager Server process that performs analytics
calculations. It does not store data. You can distribute the load by starting a separate analytics process on
one or more remote hosts to perform just the dynamic threshold (DT) portion of analytics processing.
If a remote processor server goes down, vCenter Operations Manager continues to collect and store data,
but dynamic thresholds are not recalculated based on the new data.
